THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Note • Undergoes European Quality Insurance System (CECC) OVERLOAD Heavy overloads can be endured in the form of short pulses < 0.1 s. Particular requirements should be submitted to Vishay Sfernice, specifying peak voltage, cycle and environmental conditions. RECOMMENDATIONS FOR USE Since these components are high dissipation power resistors, customers are advised to use a high melting point 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. Group Mounting In a still atmosphere, a distance between axes equal to five times the resistor’s diameter is recommended. Cabinet Mounting • Unventilated box: Dissipation should be reduced (see dimensional drawing). • Forced ventilation: If conditions are appropriate, dissipation may be doubled or even trebled. • In any case: The surface temperature at the hottest point should not exceed 450 °C. These aspects should be considered by the end user.
