Any value available within resistance range
The basic features of Vishay Bulk Metal® Foil resistors; tight
resistance tolerance, fast response time, low TCR, and
exceptional long-term stability, are available for power-circuit
applications. Typical applications are non-inductive design,
current sensing applications, deflection amplifiers, constant
current power supplies, forced balance electronic scales,
graphic display computers, character generation on CRTs,
and electron beam controls.
Our Application Engineering Department is available to
advise and to make recommendations. For non-standard
technical requirements and special applications, please
contact us.

Notes
1. Whichever is lower.
2. Heat sink chassis dimensions and requirements per
MIL-PRF-39009:
3. Inductance (L) due mainly to the leads.
4. The resolution limit of existing test equipment (within the
measurement capability of the equipment, or "essentially zero").
5. Not to exceed power rating of resistor.
6. µV/°C relates to EMF due to lead temperature difference and
µV/watt due to power applied to the resistor.
7. Vishay test data as compared to MIL-PRF-39009 is shown for
illustration purposes, Vishay test conditions that deviate from the
MIL test method are noted within parentheses.
8. Maximum ambient temperature rating is + 150 °C.
9. Maximum overload rating is 15 W (5 x rated power in free air;
1.5 x rated power on heat sink), with applied voltage not to
exceed 750 V.
10. R’s are as shown plus 0.001
to allow for measurement errors
at low resistance values.
