PolySwitch Resettable Devices - Telecommunications & Networking Devices
PolySwitch Resettable Devices Telecommunications & Networking 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 surges as defined in ITU, Telcordia GR1089, and UL60950. Available in chip, surface-mount, and radial-leaded configurations, PolySwitch devices help improve the reliability of customer premise and network equipment world wide.

Voltage Ratings for Telecommunications and Networking Devices For Raychem Circuit Protection telecommunications devices there are two applicable voltage ratings. These are VMax Operating and VMax Interrupt. To help understand the nature of these two different voltage ratings, the following definitions are provided: VMax Operating : For telecommunications devices this is the voltage used to obtain component recognition under UL1434. Most Raychem Circuit Protection devices are certified at 60V but can withstand higher VMax Interrupt conditions as noted above. See Table T3 for its VMax Operating. *VMax 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 conditions, as listed above, to assist equipment in meeting the appropriate industry conditions.

Notes: IH : Hold current: maximum current device will pass without interruption in 20C still air. IT : Trip current: minimum current that will switch the device from low resistance to high resistance in 20C still air. VMax Operating : Maximum continuous voltage device can withstand without damage at rated current. This voltage is used for component recognition under UL1434. VMax Interrupt : Maximum voltage that can be safely placed across a device in its tripped state. Devices have been designed to trip safely under higher level power cross conditions to assist equipment in meeting the appropriate ITU, UL60950, or GR1089 industry requirements. IMax Interrupt : Maximum fault current device can withstand without damage at rated operating voltage. This current is used for component recognition under UL1434. Devices have been designed to trip safely under higher level power cross conditions to assist equipment in meeting the appropriate ITU, UL60950, or GR1089 industry requirements. PD : Power dissipated from device when in the tripped state in 20C still air. RMin : Minimum resistance of device as supplied at 20C unless otherwise specified. : Maximum resistance of device as supplied at 20C unless otherwise specified. RMax R1Max : Maximum resistance measured one hour post-trip or post-reflow at 20C. * ** 250VAC interrupt products are designed to help equipment pass ITU K.20, K.21, & K.45 recommendations and Telcordia GR-1089 Port Type 2 & 4 requirements. 600VAC interrupt products are designed to help equipment pass UL60950, TIA-968-A and GR1089 Port Type 1, 3 & 5 requirements. Product is not currently available in a resistance matched or sorted option. R1Max measured 1 hour post-trip, or 24 hours post-reflow at 20C.

Warning :
* Users should independently evaluate the suitability of and test each product selected for their own application. * Operation beyond the maximum volatge or current 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. * Operation in circuits with a large inductance can generate a circuit voltage (L di/dt) above the rated voltage of the PolySwitch resettable device. This product should not be used in an application where the maximum interrupt voltage can be exceeded by inductive spikes. * A PPTC device is not a fuse - it is a nonlinear thermistor that limits current. Under a fault condition all PPTC devices go into a high resistance state but do not open circuit, so hazardous voltage may be present at PPTC locations. * Contamination of the PPTC 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. * PPTC devices are not recommended to be installed in applications where the device is constrained such that its PPTC properties are inhibited, for example in rigid potting materials or in rigid housings, which lack adequate clearance to accommodate device expansion.

Resistance-sorted and Resistance-matched Devices
Most TCF TRF and TS devices are available in resistance-sorted and/or resistance-matched versions. ,
Resistance-sorted Devices
Resistance-sorted devices (part number suffix "Rx" where x = 1, 2, A, B, C, F etc.) are supplied with resistance values that are within , specified segments of the device's full range of resistance. Feature * Narrow resistance range. Benefits * 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.
15
Resistance-matched Devices
Resistance-matched devices are supplied such that all parts in one particular package (or reel) are within 0.5 of each other (1.0 for TRF250-080T 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. Benefits * Resistance-matched devices may reduce the tip-ring resistance differential, reducing the possibility of line imbalance.
