Power Resistors

Wire wound resistors use round or flat wire, corrugated tape or a meander as the active material. Depending on the design and the resistance value, ceramic, mica or glass fiber are used as the carrier material.


The core element of a PTC resistor is the ceramic PTC thermistor. The special feature of this resistor is the positive temperature coefficient, which causes the original resistance value to increase exponentially from a step temperature of approx. 140°C.

Electronic Controllers

For stepless control and regulation of fans for heating/air conditioning (HVAC) as well as for engine cooling systems in vehicles, the KRAH Group develops and produces electronic solutions together with partners.

We are 2nd Tier supplier
for leading manufacturers


We help industrial companies to increase their reliability in the longevity of their products and their fleet. We know the challenges of the industrial sector very well and respond to them with innovations in electrical components.


The energy concept of the future is inconceivable without electromobility. Electric cars are the beginning of a different logic of energy and mobility.


In terms of sales, the automotive industry is by far the most important industrial sector in Germany. In order to be able to guarantee the quality of the vehicles, the electronics must meet equally high standards.

Competition for companies in all sectors is constantly increasing. In the battle for customers and skilled workers, the maxim is "higher, faster, further!". Companies at all levels are looking for ways to reduce costs, improve working conditions for their employees and optimize processes. A central, often underestimated starting point: the reliability of electronic assemblies and components. KRAH is your partner for highest quality electronics. As a market-leading manufacturer and developer of electrical resistors for the automotive industry, we also supply industrial customers in the following sectors:
