Does Thick Sound have a metal film resistor?

The Housheng brand does indeed produce metal film resistors, which belong to the thin film resistor series. The following is a detailed introduction about the series:
1、 Series positioning and core technology
The thick sound thin film resistor series adopts metal film technology and deposits high-purity metal (such as nickel chromium alloy) on an alumina ceramic substrate through vacuum coating process to form a resistor layer. It has the following core characteristics:
High precision: The resistance accuracy is usually within ± 1%, and high-end products can reach ± 0.1%, ensuring precise control of circuit parameters.
Low Temperature Coefficient (TCR): The TCR value is controlled within ± 100ppm/℃, which is much better than ordinary thick film resistors (usually above ± 200ppm/℃), and maintains stable resistance in temperature changing environments.
Wide resistance range: covering 1 Ω -10M Ω, meeting different circuit requirements.
2、 Product parameters and performance

Physical specifications:

Surface mount: Sizes include 0201, 0402, 0603, 0805, 1206, etc., suitable for miniaturized electronic devices.
Plug in type: The pin length is divided into three levels: 3mm, 5mm, and 7mm, suitable for traditional through-hole board design.

Electrical characteristics:

Tolerance level: available in two levels: ± 1% and ± 5%.
Rated power: 0.125W-5W, covering low to medium power scenarios.
Voltage resistance strength: 500V/mm, insulation resistance>10G Ω, ensuring electrical safety.

Environmental adaptability:

Working temperature range: -55 ℃ to+155 ℃, suitable for extreme environments.
Thermal stability: After 1000 hours of testing in an 85 ℃/85% RH environment, the resistance change rate is less than ± 1.5%.
3、 Application scenarios
Thick sound metal film resistors are widely used in the following fields due to their high precision and stability:
Communication equipment: Ensure precise control of signal transmission.
Automotive electronics: Maintain stable performance in high-temperature environments such as engine control units (ECUs) and in car entertainment systems.
Industrial control: suitable for current/voltage regulation in precision instruments and automation equipment.
Medical electronics: Plays a role in scenarios such as monitors and diagnostic equipment that require high precision.
Consumer electronics: power management modules in portable devices such as smartphones and tablets.
4、 Purchase and Technical Support
Thick metal film resistors can be purchased through electronic component distributors such as Digi Key and Mouser, and the thin film resistor series is clearly listed in the product catalog. In addition, Housheng provides complete technical documentation (such as specifications and testing reports) and complies with the RoHS 2.0 directive to ensure environmental compliance.
