Crown Ferrite - Absorber Plastic Grain (APG)

EMI / RFI Absorbers, Absorber Plastic Grain

APG

Absorber Plastic Grain (APG) is a special plastic grain, include absorbent material with high percentage. It’s suitable for injection molding to produce complex shape to get a good performance to solve the EMI problem in wide band till 18GHz. We not only offer the grain, but also offer the injection molding OEM service.
