The ability of a pogo pin to pass peak current is closely connected to its internal structure. In order to ensure its stable operation and avoid potential risks, we must have a deep understanding of the limitations of its current carrying capacity. When discussing this issue, we can conduct a detailed analysis from the different structures of pogo pins.

Back drill structure pogo pin
First, take the pogo pin of the back drill structure as an example. When the current exceeds 1A, the current carrying capacity of the spring loaded pin of the back drill structure becomes particularly important. This is because too high a current can cause the spring loaded pins to locally overheat, increasing the risk of burning out the spring. Therefore, when designing the spring loaded pin structure, this factor must be fully considered to ensure its stable operation under high current.

Bias tail structure pogo pin
Secondly, the pogo pin design of the bias tail structure. When the current exceeds 5A, the current carrying capacity of the bias tail is also worthy of attention. Excessively high current may cause the bevel to overheat, also increasing the risk of spring loaded pin damage. Therefore, during the design process, the current carrying capacity of the spring loaded pin of the bias tail structure must be reasonably evaluated to ensure its safety under high current.

Ceramic bead structure pogo pin
In addition, the spring loaded pin with ceramic bead structure is a special structure. The ceramic bead structure has excellent high temperature resistance and therefore its current carrying capacity is relatively strong. However, this does not mean that its current carrying capabilities can be completely ignored during the design process. In fact, the current carrying capacity of the ceramic bead structure is still related to the diameter of the needle. If the diameter of the needle is not large enough, the temperature of the needle may rise rapidly when high currents are passed, increasing the risk of damage.
To sum up, in order to ensure the stable operation of the pogo pin when over-peak current occurs. Engineers must fully consider the current-carrying capabilities of their internal design structures, as well as the relationship between the ceramic bead structure and needle diameter. The safest approach is to design the normal current structure according to the peak current to ensure the reliability and safety of the pogo pin under various working conditions.
