Product type
Thin film resistors are precision passive components that offer high accuracy and stability in electrical circuits. They are typically made from a thin layer of resistive material deposited on a substrate, which allows for precise control over resistance values. These resistors are known for their low temperature coefficient and excellent performance in various applications, making them ideal for high-frequency and high-precision circuits.
| Resistance range | 1 ohm to 10 megohms |
| Tolerance | ±0.1% to ±5% |
| Temperature coefficient | ±5 to ±50 ppm/°C |
| Power rating | 1/8 W to 1 W |
| Substrate materials | Ceramic or glass |
When selecting thin film resistors, consider the required resistance value, tolerance, and temperature coefficient for your application. It's essential to specify the power rating and substrate material based on the operating environment. Buyers should also inquire about the quantity needed, as bulk orders may qualify for discounts. Certifications such as RoHS compliance may be important depending on regulatory requirements.
