HVP Series High Voltage Thick Film Planar Resistors?
The HVP series is a range of high voltage thick film resistors in a thin single in-line package planar format, designed for through-hole PCB mounting in high voltage circuits where board space is constrained and resistance values in the megohm-to-gigaohm range must be combined with kilovolt-level standoff voltage. Fourteen models are offered across three distinct body families. The C-type series — HVP 3C through HVP 9C — comprises seven body sizes with power ratings from 0.5W to 1.1W and maximum working voltages from 4kV to 10kV, in a compact profile with a height of 6.5mm and lengths from 10.8mm to 26.0mm. The L-type series — HVP 4L, 5L, and 6L — offers a lower-profile format at 5.08mm height for the same resistance range but at reduced voltage ratings. The X-type and D-type bodies — HVP 11X, 18X, and 18D — address higher power and voltage duties, with the HVP 18X rated at 2.7W and 15kV and the HVP 18D at 4W and 15kV in a 48.9mm body with a 13.2mm height.
The resistance range across the series spans 1MΩ to 1GΩ for the majority of models, with the HVP 4L covering a narrower 2MΩ to 10MΩ range at a 1kV working voltage. Each model offers two resistance sub-ranges with differing TCR grades: a tighter sub-range up to 100MΩ to 200MΩ at ±50 ppm/°C, available only in ±0.5% and ±1% tolerances, and a broader sub-range extending to 1GΩ at ±250 ppm/°C, available across ±1% through ±20% tolerance grades. The HVP 18D carries a single TCR grade of ±100 ppm/°C across its full 1MΩ to 1GΩ range. This tiered structure allows the engineer to select the appropriate combination of precision and voltage rating for the specific sub-circuit duty, with the tighter TCR sub-range serving precision divider and measurement functions and the wider sub-range serving general high-impedance and protection applications.
All HVP models are encapsulated with a flame retardant coating rated to UL94V-0, and terminations are lead-free in compliance with the EU RoHS directive, noting that lead-containing glass within the electrode, resistive element, and glass layers is not within the scope of the RoHS restriction. The operating temperature range is −25°C to +125°C with a rated ambient temperature of +70°C, above which power derating applies in accordance with the published derating curve. Solder heat resistance is ΔR ≤1% maximum at 260°C for 10 seconds, and rapid temperature change performance is ΔR ≤1% maximum across five cycles of −25°C to +125°C, confirming suitability for reflow and wave soldering processes and for deployment in equipment subject to thermal cycling in service.

Applications of the HVP Series High Voltage Thick Film Planar Resistors
Where RARA high voltage resistors are deployed in the field.
High voltage power supply feedback and voltage division networks — precision divider chains and output sensing elements in HVDC, electrostatic, and laser power supplies where the ±50 ppm/°C TCR sub-range and ±0.5% tolerance maintain output accuracy across operating temperature variation.
Medical imaging and X-ray equipment — voltage sensing, monitoring, and feedback resistors in the high voltage stages of X-ray generators, CT scanners, and fluoroscopy systems, where compact SIP placement allows integration into space-constrained high voltage PCB assemblies alongside other components.
High voltage test and measurement instrumentation — precision attenuator and divider elements in high voltage oscilloscope probes, kilovoltmeters, insulation resistance testers, and calibration sources where PCB-mountable high-impedance components at kilovolt ratings are required.
Electrostatic and photocopier systems — high-impedance voltage sensing and control resistors in the electrostatic charging and transfer stages of reprographic equipment and electrostatic coating systems operating at kilovolt-range bias voltages.
Industrial high voltage control and monitoring circuits — voltage sensing, overvoltage detection, and bias elements in industrial plasma, corona discharge, and ion beam equipment where through-hole SIP mounting integrates directly into drive and control PCBs.
Power conversion and inverter systems — high-impedance bleeder and voltage equalisation resistors in series-connected capacitor banks, multi-level converter assemblies, and switched-mode power supplies operating at elevated bus voltages requiring compact high-resistance board-mounted components.
Telecommunications and RF transmitter power supplies — stable high-resistance planar elements for voltage monitoring and conditioning in transmitter and antenna system power stages where PCB integration is preferred over through-hole axial or tubular alternatives.
Scientific and laboratory instruments — high-value, high-voltage resistors in mass spectrometer power supplies, electron gun bias networks, and laboratory high-voltage sources where the thin SIP format minimises board footprint without compromising the creepage distance needed for reliable kilovolt-level operation.
