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