Summary:
|
This supplement addresses narrow pin spacing in connectors with limited creepage and clearance dimensions but high-power loading, which can potentially make them susceptible to high impedance shorts between connector pins or arcing during the connecting/disconnecting mating cycle. These shorts and arcs can result in thermal and fire hazards for such high-power connectors and negatively impact overall system reliability.
|
Comment:
|
Scope: Small form factor connectors have very limited creepage and clearance dimensions that can potentially make them susceptible to high impedance shorts between pins of the connector.
