Heatsink Encased Wirewound Power Resistors
FEATURES
• 5 W to 50 W at 25 °C
• NF C 83-210
• According to CECC 40 203
• High stability < 0.05 % year
• Low temperature coefficient typically ± 15 ppm/°C
• Wide range of values from 0.006 Ω to 130 kΩ
• Termination = Sn/Ag/Cu
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
Encased in a compact and light heatsink offering complete environmental protection, great mechanical strength and easy
mounting. Non inductive versions can be supplied under the RHNI designation (please indicate required specifications and
frequency range upon ordering).
NF F 16101, 10/1988 and 16102, 04/1992: Not applicable (our parts contain less than 10 g of combustible materials).
