Onboard Contact: OG-453239-A
SMT grounding contact for engine compartment PCB
- Connecting a GND layer of PCB with multiple points on a chassis can be expected to suppress radiation noise
- Connectors are prone to static electricity. When the OG is placed near a connector, it creates a ground connection with the chassis to release the static electricity
- The spring structure has durability for 10 million vibrations, considering the deflection of PC boards caused by vibration
- Sustained conduction is secured because of unique dimple design
- Can be used under high temperature at 150ºC
- RoHS Compliant
