The Cylindrical Thick-Film Non-Inductive High-Voltage Resistor is a high-performance resistive component specifically designed for high-voltage, pulse, and surge circuits. This series of resistors utilizes a thick-film non-inductive structure, using high-purity alumina ceramic (Al₂O₃) (over 95%) as the substrate. The resistive film is made of a conductive paste composed of precious metals such as silver, ruthenium, and palladium, and is manufactured through high-temperature sintering at 850℃, ensuring excellent thermal conductivity and electrical stability.

The housing can be encapsulated with silicone or glass, allowing for long-term operation in air, high-pressure oil, or epoxy resin environments. Its leads employ a tin-plated nut or screw structure, ensuring not only secure and reliable wiring but also improved corrosion resistance and contact stability under high-voltage conditions, making it an ideal and reliable component in high-voltage equipment.

Excellent High Voltage and Pulse Withstand Performance: Maintains stable resistance under high voltage and energy surge conditions, exhibiting excellent surge resistance.

Inductive Design: Effectively eliminates parasitic inductance, ensuring accurate signal transmission in high-frequency and high-voltage circuits.

Excellent Thermal Stability: Utilizes a high thermal conductivity ceramic substrate and precious metal resistive film, providing excellent heat dissipation and extremely low resistance drift.

Reliable Lead-Out Terminal Connection: Tin-plated nuts or screws facilitate mechanical fixing and connection to high-voltage terminals, offering corrosion resistance and vibration resistance.

High Environmental Adaptability: Maintains long-term reliable operation in media such as air, high-pressure oil, and epoxy resin.

Cylindrical thick-film non-inductive high-voltage resistors are widely used in applications requiring high voltage withstand and pulse suppression, such as:

• High Voltage Power Supplies
• Electrostatic & Discharge Systems
