Customer ServiceIn this case, there is a risk that the DC-link capacitors will not be charged completely. By using a wirewound resistor, it is possible to calculate the exact inrush currents and charging-times under all operating temperatures.
The maximum working surface temperature is up to 400 °C. The TCR varies from 75 to 200 ppm/°C, and typical resistance values are in the range from 1 Ω to 10 kΩ. The majority of the power wirewound resistors have a ceramic core and a ceramic coating to protect the winding.
The wire material has a high resistivity, and is usually made of an alloy such as nickel-chromium (Nichrome) or a copper-nickel-manganese alloy called Manganin. Common core materials include ceramic, plastic, and glass. Wirewound resistors are the oldest type of resistors that are still manufactured today.
These power wirewound resistors have a typical power rating of 25 to 50 W. This assumes that the resistor will be mounted on a metal surface to assist with the power dissipation. The maximum surface temperature is around 300 °C and the TCR is low with around 25 ppm/°C for resistance values above 50 Ω.
