Thick Film High Voltage Resistor Manufacturer

We design and manufacture application specific thick film high voltage resistor product in low to medium volume. In many applications a resistor performance issue resulting in system failure is a risk that cannot be tolerated. We understand using a standard resistor that is the closest available fit is often not a viable option.

We have many years’ experience of custom high voltage resistor design and manufacture for a wide range of applications.The main application for thick film high voltage resistors is as circuit protection elements in power supplies. Other applications include medical devices, military systems (RADAR, SONAR), Anti-static systems, motor control, high voltage resistor divider circuits and balancing and emitter resistors.


Thick Film High Voltage Resistor Manufacturing Capability

We design manufacture application specific resistor product in the U.K in low to medium volume.

Resistance - Ohmic Ranges 1 Ohm to 1,000 MOhms

Voltage maximum 80,000Volts (as single element)

Temperature co-efficient (TCR) 100ppm/°C (for standard designs)

Tolerance ±1% (for standard designs)

Wattage Ranges from low power (Watts) to KWatts depending on resistive element

The above applies for standard designs. We work with system designers to understand the application before starting the resistor design process. An analysis of data sheet parameters alone is rarely enough to ensure long term reliable performance. Ambient temperature, moisture levels, mechanical stress, handling, overvoltage and surge conditions can all have an impact on in circuit resistor performance. By utilising specialised materials and manufacturing processes we may deliver a thick film high voltage resistor suitable for any application.
