Open Air Metal Alloy Current Sense Resistors

Current sense resistors

shunt resistors

Current sense resistors are designed for sampling current with a very low resistance value from 0.005Ω to 0.1Ω and a very low inductive, offer a high current, flameproof alternative to conventional axial devices and flat chips for current-sense circuits where PC board space is at a premium. The open air resistor's footprint is reduced by extending the height of the device above the board, thus keeping the resistor element's "hot spot" safely off the PC board and providing for increased air circulation under it, which in turn provides increased heat dissipation and cooler operation.

Features

1. Low inductance. Solder ability  copper leads (60/40).

2. Radial leads, low resistance value 0.005Ω ~ 0.1Ω.

3. High stability open-air style. Precision alloys resistive element.

4. Standard tolerance ±1%, ±2%, ±5%

5. Open air design and all welded construction            

Applications

1. Inverter and Switching Power Supplies.

2. CPU Drive Control, Power Tool Motor controls.

3. Residual Battery Power Detection, Current Sensing.

1. High Accuracy: They provide precise current measurements due to their low resistance values, which range from 0.005Ω to 0.1Ω.
2. Low Inductance: This feature ensures minimal interference with high-frequency signals, making them suitable for high-speed applications.
3. High Current Handling: They can handle high currents, making them ideal for power management and protection circuits.
4. Flameproof Design: Their construction ensures safety and reliability, even under high power conditions.

Additionally, the open-air design helps in better heat dissipation and cooler operation by allowing increased air circulation around the resistor element.
