Product type
Thick film resistors are passive electronic components that provide resistance in a circuit. They are made by printing a resistive material onto a ceramic substrate, which is then fired at high temperatures to create a durable and stable component. These resistors are commonly used in various electronic applications due to their reliability and cost-effectiveness.
| Resistance range | 1 ohm to 10 megohms |
| Power rating | 0.1 W to 5 W |
| Tolerance | 1% to 10% |
| Temperature coefficient | ±100 ppm/°C to ±500 ppm/°C |
| Operating temperature | -55°C to +155°C |
| Package sizes | 0402 to 2512 |
When selecting thick film resistors, consider the required resistance value, power rating, and tolerance for your application. It is also important to specify the operating temperature range and package size to ensure compatibility with your circuit design. Certifications such as RoHS compliance may be necessary depending on the application.
