High Voltage Resistor Manufacturer

We manufacture customer specific high voltage resistor product in low to medium volume.

We have many years’ experience designing custom thick film high voltage resistor products for a wide range of high power applications and retain a detailed understanding of resistor technology, manufacturing and application issues. We understand you don't want to compromise by simply using an off the shelf resistor that does not match the exact specification but is the closest available fit. In many applications the risk of a resistor performance issue causing system failure is a risk that cannot be tolerated.

The main application for thick film high voltage resistors is sensitive circuit protection elements in power supplies but other applications include medical devices, military systems (RADAR, SONAR), Anti-static systems, motor control, high voltage resistor divider circuits and balancing and emitter resistors.

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

 

High Voltage Resistor Manufacturing Capability

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, application specific values may be manufactured by utilising specialised materials, manufacturing and test processes.

An analysis of data sheet parameters alone is rarely sufficient to ensure long term reliable performance. Ambient temperature, moisture levels, mechanical stress, handling, overvoltage and surge conditions will all have an impact on in circuit resistor performance. We therefore work with system designers to understand the nature of the application before starting the high voltage resistor design process.
