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 |

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.
