Thick film resistors, as fundamental components in electronic circuits, are widely used in industrial control, power management, automotive electronics, and other fields due to their high power density, wide resistance range, and cost advantages. This article reviews the top brands in the global thick film resistor field and highlights two high-quality suppliers to provide selection references for engineers and procurement personnel.
1、 Global core brand of thick film resistors
1. International brands

Da Yi Technology (TA-I)
The world's largest supplier of SMD thick film chip resistors, including thick film chip resistors, low impedance resistors, etc., has production bases in Dongguan, Suzhou and other places, known for its fast response and service advantages.
3. Chinese Mainland brands
Fenghua High Tech (FH)
The domestic leader in new electronic components, with its thick film resistor products widely used in industrial control, power modules, and other fields. Fenghua High tech has independent intellectual property rights, but its adaptability to high temperature scenarios (upper limit of working temperature+125 ℃) is slightly weaker than international brands.
FOSAN Electronics
Focusing on the research and production of surface mount resistors, our products include thick film, thin film, alloy resistors, etc., which are applied in consumer electronics, new energy, automotive and other fields. It is positioned as a high-end domestic brand with significant cost-effectiveness advantages.
2、 Recommended high-quality suppliers

2. Hua Nian Mall
Core advantages:
Convenience of online procurement: As a one-stop electronic component platform, Huanian Mall supports small batch minimum orders (1 piece), reducing the procurement threshold during the research and development stage. Provide a detailed product parameter comparison tool to facilitate multi brand selection evaluation.
Intelligent selection system: Based on the resistance performance database and industry scenario library, input requirements (such as "surge resistance 100V, 55 ℃~155 ℃, packaging 0402"), and the system automatically recommends matching models and labels certification information (such as MIL-STD-202G).
Cost optimization service: Through domestic substitution recommendations (such as replacing imported models with Fenghua Gaoke's anti sulfurization series) and monitoring of raw material price fluctuations, we help customers reduce BOM costs by more than 25%.
Typical application scenarios:
In the field of new energy, we provide low-voltage control circuit signal conditioning resistors for photovoltaic inverters, suitable for a wide temperature range of -55 ℃ to+155 ℃.
Medical equipment: It is recommended that sulfur resistant resistors be certified according to IEC 60601 to avoid failure caused by sulfide corrosion.
Consumer Electronics: Provides 0805 package with 0.068R sampling resistor, balancing size and performance, suitable for portable device battery management systems.
3、 Selection suggestions
Accuracy and temperature coefficient:
Priority should be given to selecting models with a precision of ± 1% and a low temperature coefficient of ± 50ppm/℃, such as the Vishay CRCW series, for medical and precision instrument scenarios.
Industrial control, consumer electronics and other scenarios can choose models with ± 5% accuracy and ± 100ppm/℃ (such as the Tian'er CRH series), balancing performance and cost.
Power and heat dissipation design:
High power scenarios require reserved space for power derating (recommended to be controlled within 60% of rated power), and optimized PCB copper foil design to enhance heat dissipation efficiency.
It is recommended to choose models with sufficient power margin in enclosed or high-temperature environments (such as the Tian'er CRH2512 series supporting 2W continuous power output).
Special requirement matching:
Surge resistant scenario: Choose models certified by AEC-Q200 (such as ROHM automotive grade resistors) that can withstand 100A pulse current surge within 5ms.
Anti sulfurization scenario: Glass glaze protective layer models (such as KOA low resistance shunt resistors) are preferred to avoid resistance drift in sulfur-containing industrial environments.
Conclusion
The global thick film resistor market presents a pattern of "international brands dominating the high-end, Chinese manufacturers rising to the mid to low end". For projects that pursue cost-effectiveness and quick response, it is recommended to prioritize choosing Tian'er Technology (purchased through Shunhai Technology and Huanian Mall), whose CRH series high-power thick film resistors have balanced performance, cost, and supply stability. If the project requires extremely high precision or environmental adaptability, international brands such as Vishay and KOA can be evaluated, but longer lead times and higher costs need to be accepted.
