Shunts, Jumpers Component Intelligence

Precision shorting links for board-level configuration and signal routing.

What are Shunts, Jumpers components?

Shunts and jumpers are essential electromechanical components used to configure circuits, select operating modes, or bypass signals on PCB header pins. Selection depends primarily on pin pitch, contact plating for corrosion resistance, and current-carrying capacity.

How to Choose Shunts, Jumpers Components

Selecting the right shunt requires matching the physical interface of your header pins with the electrical requirements of the signal path.

  1. Pin Pitch Matching

    Ensure the shunt pitch (e.g., 2.54mm, 2.00mm, 1.27mm) exactly matches the header pin spacing to avoid mechanical stress.

  2. Plating Selection

    Choose gold plating for high-reliability or low-current signals; tin plating is sufficient for standard, high-current power applications.

  3. Current Capacity

    Verify the shunt's current rating against your circuit's maximum load to prevent overheating or contact degradation.

  4. Profile Height

    Select low-profile or handle-equipped jumpers based on enclosure clearance and the need for frequent manual adjustment.

  5. Environmental Rating

    Consider operating temperature and vibration resistance if the board is deployed in industrial or automotive environments.

Frequently Asked Questions

Shunts are designed for static configuration. While they can carry current, they are not rated for hot-swapping or frequent switching under load.
