EMI Grounding
Good grounding is essential for reducing EMI noise at the board level. It is also a more cost effective solution to reduce EMI noise. Our Grounding Components work by capturing EMI signals and eliminating them with proper grounding.
Grounding technology makes part of a device equipotential with the ground portion or separates a ground portion contaminated with noise from other ground portions. KITAGAWA INDUSTRIES America offers various applications including products compatible with automated on-board mounting (SMT grounding contacts), as well as peripherals for circuit board and cables.
Today’s EMI noise issues are detected at higher frequency ranges, especially 500MHz to higher GHz range with the higher speed-processors and wireless units within the application devices. The limited space applications such as smart phones, cell phones, thin laptops have more internal noise interference between the components or cross talk issues within the applications. SMT type onboard contacts are EMI noise solutions for higher frequency ranges in combination with shielding or filtering solutions. These cost effective parts are tiny structures that can fit into small gaps.
KITAGAWA INDUSTRIES America has a wide range of SMT grounding contacts (Onboard Contacts – OG series). These are sophisticated and well-designed SMT contacts, as well as special type of contacts such as onboard plates, onboard shielding can holders, and others.
Features:
- Space-saving FG reinforcement enabled at design stage.
- Space-saving FG facilitated even where screws are precluded.
- Effective for emission and suitable for ESD immunity.
- All EMC solutions can be completed on board, includinggrounding, shielding and filtering.
- Shaped to prevent spring deformation by hook.
On-board Grounding Contacts (SMT type)
KITAGAWA INDUSTRIES America’s on-board contacts are all SMT (Surface Mount) type contacts, which give advantages of sophisticated structures and precision of work including:
- Space-saving FG reinforcement enabled at the design stage.
- Space-saving FG facilitation even where screws are precluded.
- Effective for emissions and ESD immunity.
- All EMC solutions can be completed on the board level including grounding, shielding and filtering.
- Shaped to prevent spring deformation by hook.
