Standard Type: OG Series

KITAGAWA INDUSTRIES America carries a large selection of onboard contacts (OG) that are excellent grounding materials for reducing EMI noise at the board level. Also, these parts give the ability to ground in the areas where screws are not used.

  • Space saving, FG facilitated even where screws are precluded.

  • Automated mounting on PC board is applicable.
  • Box structure is introduced for distortion, deformation and damage prevention.(excluding some part numbers)

Test experiment – How to ground effectively

Test PC Board Condition

  • Exp 1:
    PC board + Metal plate (without grounding)
  • Exp 2:
    PC board + Metal plate (4 points: A, B, C, D)
  • Exp 3:
    PC board + Metal plate (8 points: A, B, C, D, E, F, G, H)
Test experiment – How to ground effectively: Without FG connection
Test experiment – How to ground effectively: 4 points grounding
Test experiment – How to ground effectively: 8 points grounding

Test Result

Multiple grounding points noise suppression better even at higher frequencies.
* Recommended EMC grounding pitch is 1/8 of the wavelength of the target (problem) frequency.
