KEMET EMI Noise Suppression Tape FLEX SUPPRESSOR®
KEMET EMI Noise Suppression Tape FLEX SUPPRESSOR® is optimized for cable EMI issues and provides a flexible noise suppression solution by attenuating surface conduction noise and reducing radiation effectively. KEMET FLEX SUPPRESSOR offers a smart design that allows the user to simply apply it to wrap under the jacket or around the outer surface. This FLEX SUPPRESSOR tape is designed for high-frequency noise generated from electronic devices. Applications include charger, power, EMI debugging, and interface cables (HDMI, USB, LVDS, etc.).
Features
- Effective radiation suppression in wide frequency range beyond 30MHz
- Replace bulky ferrite core for smart cable design
- Applicable to wide range of cable diameters by 5mm or 10mm tape width for NST, and 9mm or 19mm tape width for EST
- Maintains cable flexibility
- Wraps around outer surface
- No space constraints
- Electromagnetic wave suppression - electromagnetic wave conducting along cable is effectively absorbed by magnetic loss, and radiation out from cable can be reduced
- Resonance suppression controls high-frequency current and suppresses unwanted electromagnetic resonance by adding resistive component of impedance
- No cutting tools required
- Easy to cut or tear by hand for EST tapes
- No adhesive tape liner, simplifying the wrapping process for EST tapes
- Easy to wrap due to vinyl tape size
- Aluminum layer stack-up available on request
- RoHS compliant and halogen free
Applications
- Charger cables
- Power cables
- Interface cables (HDMI, USB, LVDS, etc.)
