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.
