PolySwitch Telecommunications and Networking Resettable Devices

Transcription

1 Telecommunications and Networking PolySwitch Telecommunications and Networking Resettable Devices PolySwitch devices for telecommunication and networking applications were initially designed over ten years ago to meet the growing demand for resettable overcurrent protection. These product families help provide protection against power cross and power induction surge as defined in ITU, Telcordia, and UL. vailable in chip, surface-mount, and radial-leaded configurations, PolySwitch devices help improve the reliability of customer premise and network equipment world wide. enefits: Many product choices give engineers more design flexibility ompatible with high volume electronics assembly ssist in meeting regulatory requirements Improved line balance pplicable for legacy POTS and modern digital communications equipment. Features: Resettable overcurrent protection Surface-mount, radial-leaded, and chip form factors Fast time-to-trip gency recognition: UL, S, TÜV Resistance sorted and matched devices available Low parasitic capacitance/flat impedance with frequency Products in this section are grouped by: pplication/specification, Product Series, Hold urrent Target pplications: Modems Phone sets Fax machines Phone wall outlets larm systems PX systems MDF modules nalog and digital line cards T1/E1 equipment xdsl modems and splitters Powered ethernet systems VoIP (Voice over IP equipment) LN, WN equipment ustomer premise equipment ccess network hardware Raychem ircuit Protection PolySwitch Telecommunications and Networking Resettable Devices 285

2 Selection Table for Telecommunications and Networking Devices Step 1. Review the Protection pplication Guide on page 287 which is based on the agency specification required to qualify the final equipment. Use the selection guide to narrow your product selection based on key device characteristics. Step 2. Verify that the PolySwitch device hold current will accommodate the telecommunications circuit s maximum ambient temperature and normal operating current. Look across the top of the thermal derating table T2 on page 290 to find the temperature that most closely matches the circuit s maximum operating temperature. Look down that column to find the value equal to or greater than the circuit s normal operating current. Now look to the far left of that row to find the part number for the PolySwitch telecommunications device that will best accommodate the circuit. Note: The thermal derating curves in Figure T1 on page 291 are the normalized representations of the data in the thermal derating table. Step 3. Verify that the time-to-trip characteristic of the chosen device meets the protection requirements of the telecommunications equipment circuit. Time-to-trip is the amount of time it takes for a device to switch to a high resistance state once a fault current has been applied across the device. Identifying the PolySwitch device s time-to-trip is important in order to provide the desired protection capabilities. If the device you choose trips too fast, undesired or nuisance tripping will occur. If the device trips too slowly, the components being protected may be damaged before the device switches to a high resistance state. Refer to typical time-to-trip curves (Figures T11-16) on pages for each of the PolySwitch devices. If the PolySwitch device s time-totrip is too fast or too slow for the circuit, go back to Step 2 and choose an alternate device. Step. Verify ambient operating condition. Ensure that your application s minimum and maximum ambient temperatures are within the operating temperature range of -0 to 85. Step 5. Independently evaluate and test the device. PolySwitch devices assist your telecommunications equipment in meeting agency requirements. To confirm your selection, independently evaluate and test the device to the application requirements. 286 PolySwitch Telecommunications and Networking Resettable Devices Raychem ircuit Protection

See below for details Voltage Ratings for Telecommunications and Networking Devices For Raychem ircuit Protection telecommunications devices (T, TG, TRx, TSx series) there are two applicable voltage ratings. These are V MX Operating and V MX Interrupt. To help understand the nature of these two different voltage ratings the following definitions are provided: V MX Interrupt: Under specified conditions this is the highest voltage that can be applied to the device at the maximum current. Devices have been designed to trip safely under higher power level cross condtions, as listed above, to assist equipment in meeting the appropriate industry conditions. V MX Operating: For telecommunications devices this is the voltage we have used to obtain component recognition under UL13. Raychem ircuit Protection devices (T, TG, TRx, TSx series) are recognized at 60V but can withstand higher V MX interrupt conditions as noted above.

Resistance-sorted Devices Resistance sorted devices (part number suffix Rx, where x = 1, 2,,,, F etc.) are supplied with resistance values that are within specified segments of the device s full range of resistance. Feature Narrow resistance range. enefits Greater flexibility for design engineers. Lower resistance devices can allow for increased loop length on line card designs. Higher resistance devices may provide greater protection by offering faster time-to-trip. Resistance-matched Devices Resistance-matched devices are supplied such that all parts in one particular package (or reel) are within 0.5Ω of each other (1.0Ω for TR T devices). Individual matched packages are supplied from the full resistance range of the specified device. Feature Tighter resistance balance between any two parts in a package. enefit Resistance-matched devices may reduce the tip-ring resistance differential, reducing the possibility of line imbalance.

22 Solder Reflow and Rework Recommendations for Telecommunications and Surface-Mount Devices Solder Reflow Recommended reflow methods: IR, vapor phase oven, hot air oven. Surface-mount devices are not designed to be wave soldered to the bottom side of the board (with the exception of minismd01). Recommended maximum paste thickness of 0.25mm (0.010 in). Devices can be cleaned using standard industry methods and solvents. Temperature ( ) Preheating Figure T19 Soldering ooling Rework If a device is removed from the board, it should be discarded and replaced with a new device to to 20 Time(s) 120 UTION: If reflow temperatures exceed recommended profile, devices may not meet the performance requirements. Leaded devices are not designed to be compatible with reflow manufacturing operations. Recommended solder/temperature exposure for leaded devices is designated in the environmental/ physical tables for the product family. Exposure to temperatures or duration at temperature in excess of these values may lead to device not meeting performance requirements. 306 PolySwitch Telecommunications and Networking Resettable Devices Raychem ircuit Protection

28 WRNING: Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame. The devices are intended for protection against occasional overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. ontamination of the PPT material with certain silicon based oils or some aggressive solvents can adversely impact the performance of the devices. Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and mechanical procedures for electronic components. Operation in circuit with a large inductance can generate a circuit voltage (L di / dt ) above the rated voltage of the PolySwitch resettable device. 312 PolySwitch Telecommunications and Networking Resettable Devices Raychem ircuit Protection
