Thick Film High Voltage Resistor Manufacturer
We design and manufacture application specific thick film high voltage resistor product in low to medium volume.
A wide range of standard high voltage resistor products is available that are suitable for most applications. However, for some more demanding and specialist applications using a standard resistor that is the closest available fit is not a viable option. A resistor performance issue resulting in system failure is a risk that cannot be tolerated.
We have many years’ experience of custom high voltage resistor design and manufacture for a wide range of applications. These include circuit protection elements in power supplies, 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. For standard designs we cover:
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
We work with system designers to understand the application before starting the high voltage resistor design process. An analysis of datasheet 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.
Required High Voltage Resistor Application Information
Most specialist thick film high voltage resistor manufacturers will have a detailed understanding of resistor materials, design limits and manufacturing processes. However, only the system designer can understand the system requirements, steady state and transient conditions and mechanical and environmental limitations.
To ensure all issues are considered we will need the following information:
- Operating Power
- Maximum continuous current
- Maximum continuous voltage
- Peak voltage/waveshape
- Required resistance value
- Resistor tolerance
- Tcr (ppm/C)
- Surge conditions (amplitude and waveform)
- Operating temperature range
- Max ambient temperature
- Environmental conditions
- Available board area.
- Resistor mounting method
- Termination type and material.
- Length of pin.
- Expected in service life.
- Target component cost.
- Quantity required.
- Required Date.
After considering this information we will deliver an honest assessment of what can and cannot be achieved, cost implications of various options and timescales. In some cases, it may be necessary to manufacture a set of prototypes for approval before proceeding to manufacture of production parts.
