Performance Data

Note: A 0.01 Ohm addition to be added to the performance of all resistors <10 Ohms.

Pulse Performance Data

Lightning Surge

Resistors have been tested in

accordance with IEC 60 115-1 using

both 1.2/50µs and 10/700µs pulse

shapes. Also, the 2512 size has

been tested to the Bellcore GR1089

2/10µs and 10/1000µs pulse shapes.

The limit of acceptance is a shift

in resistance of less than 1% from

the initial value.
