Jumper resistors(sampling resistors)are produced by CNC automatic computerized molding machine from precision resistance alloy materials. It exhibits small resistance, high precision, high-frequency and non-inductive characteristics. It can be widely used in computers, printers, inverter-aided air conditioners, power amplifiers, power suppliers, automatic instrumentation and other fields. Currently available: various forms of jumper resistors of 1~3W 0.002-0.10Q, and at the same time we provide designing according to customer requirements.
| Resistance: | 0.002~0.1 Ω | Rated Power: | 1-3w |
| Model Number: | jumper resistor | Technology: | Wirewound |
| machine | CNC automatic computerized molding machine |
Spring (Automatic Computerized Spring Machine)It's capable of processing extension spring, torion spring, compression spring, plate spring and other springs of special shape. It's highly accurate as the quality is fully controlled by the computerized devices.
Precision resistance alloy which exhibits a small temperature coefficient of resistance, good stability and high mechanical strength can be used for sophisticated electronicdevices,measuring instruments,
as well as defense and aerospace engineering.
