Precision Metal Film Fixed Resistors

图片
Precision Metal Film Fixed Resistors Product Description The metal film resistor  is made of a thin film of metal that is deposited onto a ceramic substrate. The metal film is usually made of nickel-chrome or tin-oxide, and its thickness determines the resistance value of the resistor. The substrate provides the physical support for the metal film, and it also provides insulation between the metal film and other components in the circuit. type  Dimensions(mm) L±0.5 D±0.5 d±0.02 H±1.0 1/8W 3.5 1.7 0.42 26.0 1/4W 6.0 2.3 0.45 26.0 1/2W 9.0 3.0 0.55 26.0 1W 11.5 4.5 0.65 26.0 2W 15.5 5.0 0.70 26.0 3W 17.0 6.0 0.70 26.0 The metal film resistor is widely used in electronic circuits due to its high precision and stability. It has a low noise level, which makes it suitable for use in high-frequency applications. It also has a high operating temperature range and can withstand high voltage levels. The High Precision Film Fined Resistor  is available in a wide range of resistance values and pow

Power Wirewound Resistors

Power Wirewound Resistors Product Description A power resistor is a type of resistor designed to handle higher power loads than standard resistors. They are used in a variety of applications where high-power dissipation is required, such as in power supplies, amplifiers, and motor control circuits. Power resistors  come in a range of sizes and power ratings, from a few watts to several kilowatts. They are typically made of materials with high thermal conductivity, such as ceramic, aluminum, or silicon, to help dissipate the heat generated by the resistor.
