How much current can header pins carry?
That says, it averages 4 to 6 amps per pin. Based on the common design and material, most headers will have similar properties. When used for stacking, as in two boards soldered to the same header, the max amperage is 3 amps @ 80 degrees C (I’m assuming per pin).
How do I choose an electrical plug?
There are several criteria to consider when selecting electrical interconnect components, including:
- Current rating (current density)
- Connector size (circuit density)
- Engagement force.
- Wire size.
- Configuration and circuit size.
- Operating voltage.
- Agency approvals.
- Price per circuit.
What makes gold the best power supply connector?
Gold offers both a high melting point (minimizing wear with use) and low resistance (minimizing voltage drops). This makes gold the best choice for these applications. The designer can choose to spread high current from the power supply module over several contacts.
What should the plating thickness of a gold connector be?
Thin Plated Gold Connectors or Contacts (4-20uin or 0.1-0.5um) For gold connectors used in a controlled environment with minimal wear considerations, common gold plating thickness is between 4-20uin (0.1-0.5um).
How can I increase the wear resistance of my gold connector?
One method to increase both the corrosion protection and wear resistance of gold connector is to increase the thickness. As the gold plating thickness increases the pores in the deposit become reduced in size and quantity.
Is the current rating of a JST connector per pin?
Yes it’s per pin, however I think you’re talking about paralleling contacts to double the capacity. The current will be more likely to share more-or-less evenly if your wires are at least 1ft (30cm) long (and at least roughly matched in length).
