RWM
Vishay Sfernice
FEATURES
• High dissipation up to 30 W (25 °C)
• Fire Proof
• Excellent Endurance typical drift ± 1.5 % after
1000 h
• Conformal Vitreous Enamel
• All Welded Construction
• Low ohmic values 0.1 Ω available
• Termination: Sn/Ag/Cu
As a result of more than 50 years of experience and
continuous improvements the RWM Series of resistors
features proven reliability in AC or DC applications.
The high quality of the RWM resides mainly in the use of a
proprietary VISHAY SFERNICE enamel fired at high
temperature and free from any compound liable to corrode
the resistive wire. The performance of this series of professional resistors fully
meets the requirements of the following specifications:
– NF C 83-210-001
– CECC 40201-001
– BS - CECC 40201-002
