1/2W 1/4W 1/8W metal film precision resistor 100k resistor color code

• Product Description

The carbon film resistor is one of the film resistors. It uses high-temperature vacuum coating technology to attach carbon to the surface of the ceramic rod to form a carbon film, and then cut it with a suitable joint, and the surface is coated with epoxy resin to protect it. The surface is often coated with a green protective lacquer. The thickness of the carbon film determines the magnitude of the resistance, and the thickness of the control film and the groove are usually used to control the resistor. Carbon film resistance is also called "thermal decomposition carbon film resistance". A thin film resistor in which a hydrocarbon thermally decomposes at a high temperature in a vacuum deposits on a substrate. Low price, stable performance, wide resistance and power range.

•  Main features

1. Accuracy: 2% 5%, high precision, precision resistance can be made by adjusting the resistance value of the film cutting thread.
2. Resistance range: The resistance range is wide, generally 2.1Ω~10MΩ.
3. Nominal resistance: E-48.
4. The limit voltage is high.
5, excellent long-term stability, the voltage change has little effect on the resistance value, and has a negative temperature coefficient.
6, the packaging method is equipped with tape, bulk.
7, high-frequency characteristics are good, can be made into high-frequency resistors and ultra-high-frequency resistors, the inherent noise electromotive force is small, below 10UV / V.
8. The rated power is 1/8W, 1/4W, 1/2W, 1W, 2W, 5W, 10W.
9. The pulse load is stable and the adaptability to the pulse is good. It is used in a wide range of applications for AC, DC and pulse circuits.
