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.
