In the field of high-power resistors, various brands have formed different competitiveness based on material technology, power density, packaging technology, and application scenarios. The following is a classification of mainstream and distinctive brands in the current market:
1、 International leading brand
Vishay (USA)
Representative of high reliability products, covering alloy resistors, metal film resistors, etc., with a power range of 1W~100W+and a TCR (temperature coefficient) as low as ± 50ppm/℃. Especially in high stability scenarios such as industrial power supply and rail transit, it dominates.
Bourns (USA)
Recently launched Riedon ™ PF2203 (TO220) and PFS35 (DPAK) series thick film resistors support 35W power, 55 ℃~+175 ℃ wide temperature operation, ± 1% accuracy, suitable for high power density designs such as battery energy storage systems (BESS) and industrial motor drives.
KOA (Japan)
We specialize in precision alloy resistors and current detection resistors, with a focus on automotive grade and medical equipment applications. Our advantages lie in low temperature drift (± 50ppm) and high impact resistance.
ROHM (Japan)
Provide high integration power semiconductor module matching resistors, such as load resistors, splitters, etc., suitable for new energy vehicle electronic control systems.
2、 Featured technology brand
Viking (Taiwan, China)
TO247/TO220 packaged resistors have a power coverage of 20W~100W (such as TR100 series), with a minimum resistance of 0.05 Ω and support for ± 0.5% accuracy. They are specifically designed for instantaneous high load scenarios such as UPS power supplies and electric vehicle fuel cell systems.
Ohmite (USA)
Our strengths lie in aluminum shell resistors and water-cooled resistors, with a power of over 500W, used for heat dissipation needs of high current equipment such as power regulators and industrial frequency converters.
3、 Domestic representative brands
YAGEO (Taiwan, China)
The global leader in resistor production capacity, with a complete product line coverage, outstanding cost-effectiveness of medium and high power thick film resistors, widely used in consumer electronics and industrial power modules.
Fenghua High tech (FH, Chinese Mainland)
State owned leading brand, equipped with standard grade alloy resistors (such as STE series) and sulfur resistant resistors for the main trolley, with a power range of 0.5W~5W, used for BMS systems and photovoltaic inverters in new energy vehicles.
Fujie Electronics (Chinese Mainland)
Specializing in high-power surface mount resistors (such as HTE wide electrode series), supporting 5W~10W power, with a focus on "fast delivery time+customization", replacing the obvious demand for imports, and suitable for photovoltaic and communication power supplies.
Walter
Representatives in the field of alloy resistors, such as HTE3921 (5W, 0.01 Ω), have low resistance and high precision (± 1%), suitable for current sampling in servo drives.
Summary and Suggestions
Pursuing high power density: Preferred Bourns (TO220/DPAK package) Viking（TO247）；
Need for vehicle specifications/industrial grade reliability: Vishay, KOA, Fenghua High Tech are more compatible;
Cost sensitive alternatives: Fujie Electronics and Huade have the advantages of rapid response and localized services.
The actual selection needs to consider parameters such as power requirements, packaging limitations, temperature drift requirements (TCR), and pay attention to the manufacturer's RoHS/IATF16949 certification adaptability.
