In today’s rapidly evolving power electronics landscape, engineers and designers require components that deliver reliability, precision, and durability under high-stress conditions. Thick film power resistors stand out as a premier solution — engineered to meet the rigorous demands of industrial, automotive, renewable energy, and high-voltage systems. With power ratings from 100W to 250W, resistance values spanning from 0.1Ω to 100MΩ, and ultra-low parasitic inductance below 40nH, these resistors are optimized for efficiency, thermal stability, and long-term performance.
Thick Film Power Resistor
Why Choose Thick Film Power Resistors?
High Power Handling Capacity Designed for medium to high-power applications, our thick film power resistors support continuous operation at 100W to 250W. This makes them ideal for circuits where heat dissipation and power density are critical — such as motor drives, inverters, and power supplies.
Wide Resistance Range for Versatility Whether you need milliohm-level shunts or megaohm-level voltage dividers, our resistors cover an expansive range: 0.1Ω to 100MΩ. This flexibility allows seamless integration into diverse circuit designs without compromising on accuracy or tolerance.
Ultra-Low Parasitic Inductance (<40nH) Minimizing unwanted inductive effects is crucial in high-frequency or switching applications. Our thick film resistors feature <40nH parasitic inductance, ensuring stable performance even in fast-switching environments like IGBT snubbers, PWM controllers, and DC-DC converters.
High Dielectric Strength (Up to 4KVrms) Safety and insulation integrity are paramount in high-voltage applications. These resistors are tested to withstand up to 4KVrms insulation voltage, making them suitable for use in AC/DC power systems, medical equipment, and EV charging infrastructure where isolation and safety compliance are non-negotiable.
Key Applications: Fixed Discharge Resistor, Voltage Equalizing Resistor, Charging Resistor
Our thick film power resistors are not just generic components — they’re purpose-built for mission-critical roles:
1. Fixed Discharge Resistor
Used extensively in capacitor banks, energy storage systems, and inverter circuits, the fixed discharge resistor ensures safe and controlled dissipation of stored energy after system shutdown. Its robust construction and consistent resistance value guarantee predictable discharge times, enhancing operator safety and system longevity.
2. Voltage Equalizing Resistor
In high-voltage series-connected devices — such as multi-cell battery packs, HVDC modules, or stacked semiconductor switches — voltage imbalance can lead to premature failure. The voltage equalizing resistor balances potential across individual cells or components, preventing overvoltage stress and improving overall system reliability.
3. Charging Resistor
Critical in soft-start circuits for large capacitors or motors, the charging resistor limits inrush current during startup, protecting downstream components from surge damage. Its high pulse tolerance and low-inductance design make it perfect for EV chargers, UPS systems, and industrial automation equipment.
Engineering Excellence Meets Real-World Reliability
Manufactured using advanced thick-film deposition technology on high-grade ceramic substrates, these resistors offer excellent thermal conductivity, mechanical stability, and corrosion resistance. Their compact form factor allows for space-saving PCB layouts while maintaining superior heat dissipation through metalized terminations and optional heatsink mounting options.
Additionally, all units undergo stringent quality control and environmental testing — including temperature cycling, humidity exposure, and vibration resistance — ensuring dependable performance in harsh operating conditions.
