Product Name: Metal Film Resistor
Product model: 1/2W
Type: Fuse
Performance: Precision
Material: metal film
Production process: membrane type non-winding type
Shape: cylindrical
Metal film resistor
It plays a non-negligible role in the electronic industry and military and aerospace fields under high-precision requirements, and is also commonly used in various wireless electronic devices.
Metal film resistors strongly protect the circuit, prevent damage to external equipment, and better protect the circuit connection and data transmission. The surface metal film is wear-resistant and oxidation-resistant, speeds up the heat dissipation of the product, and makes safety protection more assured.
Widely used in electronic equipment, used in audio equipment, computers, meters, electrical appliances, and electronic equipment.
