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

Particular requirements should be submitted to Vishay Sfernice, specifying peak voltage, cycle and Cabinet Mounting environmental conditions. Unventilated box: dissipation should be reduced (see dimensional drawing). Forced ventilation: if conditions are appropriate, dissipation RECOMMENDATIONS FOR USE may be doubled or even trebled. In any case: the surface temperature at the hottest point Since these components are high dissipation power should not exceed 450 C. resistors, customers are advised to use a high melting point These aspects should be considered by the end user. solder. For low ohmic values, the measurement becomes critical and the connecting wires resistance is to be included. The value is measured at 5 mm from the resistor body.
