Fenghua Advanced Technology (FH) is a leading passive component manufacturer in China, with over 30 years of experience in the field of resistors. Its products are renowned for their high reliability, precision, and diversity, and are widely used in consumer electronics, automotive electronics, industrial control, communication equipment, and other fields. The following is a detailed introduction to the core technology and product classification of Fenghua resistors:
1、 Core technological advantages
High precision and stability
Fenghua resistors use advanced process technologies such as metal thin films, thick films, and alloys, with some products achieving an accuracy of ± 0.05% (such as TH series thin film resistors) and a temperature coefficient as low as ± 5ppm/℃, ensuring stable operation even in extreme temperatures (55 ℃ to+155 ℃) and harsh environments.
Anti sulfurization technology: By optimizing material and structural design, the anti sulfurization ability of automotive thick film resistors is increased by nearly 10 times compared to conventional products, making them suitable for sulfur-containing environments or long-term high load scenarios.
Anti surge capability: Anti surge thick film resistors can withstand high pulse currents, extend circuit life, and benchmark performance against international standards.
Diversified packaging and power adaptation
Fenghua resistors cover the full range of package sizes from 0402 to 2512, with a power range from 1/20W (0201) to 9W (high-power alloy resistors), meeting the requirements of miniaturization and high power.
Vehicle grade products: certified by AECQ200, suitable for harsh automotive environments such as high temperatures and vibrations.
Thin design: The thickness of the alloy current detection resistor is reduced to 0.4mm, which helps to miniaturize the equipment.
2、 Main product series
