PREcharge Resistors - robust precharging resistors

High current resistors for electric vehicles are used as precharge resistors in battery connection boxes for precharging the intermediate circuit. They support safe and fast precharging of the intermediate circuit capacitor.

PREcharge Resistors: What are the advantages of our precharge resistors?

The premium high power resistors can be used to charge the DC-Link capacitor with very high pulse energy. And this can be done in a very short time, even without additional cooling. The design and electrical connection can also be customized to meet the customer's requirements.

Other advantages:

Excellent isolation performance
Standard Fast-On connection
High overload capability
AEC-Q200 compliant
Recyclable

Why high dielectric strength is crucial

Thanks to our proven manufacturing technology, we can guarantee the safe and constant function of precharging resistors. Dielectric strength is the constant on which design and function must be based.

With a dielectric strength of up to 1000 volts we are able to meet any customer requirement. Here we rely on proven processes and guarantee consistent quality for automotive applications.

Why is Miba the right partner for your precharging resistor?

Our components can be customized to meet specific customer requirements. The respective requirements are defined together with our team during the development process and implemented in customized customer solutions.

All precharging resistors are tested in our in-house test laboratory. In this way, we ensure that every single component reaches the customer in high quality.

We offer automotive-compliant manufacturing, automated according to IATF 16949 certification, in both large and small series.

Our components are AEC-Q200 tested and thus meet the highest quality standards in terms of reliability, temperature and humidity resistance, thermal shock, EMC compatibility and solderability.

Let's talk about your precharging resistor requirements.
