SAE Power GA5B-30 Power Line Filter

The SAE Power GA5B-30 is a Circuit A power line filter engineered to attenuate common mode noise and interference on AC power lines, protecting sensitive electronic systems through high-frequency rejection while maintaining low voltage drop. Rated for 30 A across dual voltage inputs, the GA5B-30 delivers insertion loss up to 30 dB at 30 MHz and operates across industrial and laboratory environments with minimal leakage current.
