leads into holes of two identical gauge plates and moving

these plates parallel to each other until the resistor body is

clamped without deformation (IEC 60294).

FUNCTIONAL PERFORMANCE

PRODUCT CHARACTERIZATION

Standard values of nominal resistance are taken from the

E96/E24/E12 series for resistors with a tolerance of ± 1 %,

or 5 %. The values of the E96/E24 series are in accordance

with IEC 60063.

Notes

• The maximum permissible hot-spot temperature is 155 °C

DERATING

The power that the resistor can dissipate depends on the

operating temperature.

PULSE LOADING CAPABILITY

Maximum allowed peak pulse voltage in accordance with

IEC 60065, 14.1.a); 50 discharges from a 1 nF capacitor charged
