SMD contact springs - type 21

contact springs are ideal for automatic assembly on printed circuit boards. They are soldered by the standard-reflow-soldering process.

The standard basic material used for SMD contact springs is beryllium (CuBe). However, other materials can also be supplied.

As standard, SMD springs are gold-plated (AU) and therefore provide excellent protection. They can be supplied in a wide range of dimensions and shapes.

  • Available in a variety of dimensions and shapes
  • Standard or customized SMD-contact springs
  • Gold-plated, other platings are possible
  • Excellent connection properties

Other dimensions on request.

Replace -XX in the item number by the desired surface plating. Standardly, springs are gold-plated. Other platings are possible:

  • AU = gold-plated
  • SN = tin-plated
  • AG = silver-plated

For reasons of space, we have summarized our SMD contact springs in types. We only use a schematic drawing for the presentation of an SMD type. You can find the exact dimensions, the proposal for the pad etc. in the relevant datasheet.
