AI Technical Summary
Existing ferrite-based EMI suppressors cannot effectively absorb common-mode EMI noise above 5GHz, and cannot meet the requirements of high-speed data transmission.
Thermoplastic EMI absorbers are used by embedding magnetic particles into thermoplastic polymer resin systems such as liquid crystal polymer (LCP), polybutylene terephthalate (PBT), polypropylene (PP), polypropylene blends, thermoplastic elastomer (TPE), polyamide (PA), or nylon through injection molding or thermoforming processes, forming an EMI suppression that can provide up to 20dB or more in the frequency range of 5GHz to 70GHz.
It achieves efficient EMI noise suppression and absorption in the frequency range of 5GHz to 70GHz, meeting the needs of high-speed data transmission, and eliminates the need for a 360-degree good electrical connection between cable shielding and connector shielding.
