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.
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 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.
