Insertion loss increases by up to 1 dB at the extreme temperatures. Imepedance for test: 100 Ω or 135 Ω. Small difference in return loss will occur. Surge Voltage Capability: Metallic 800 Vpeak 10/560 μsec. Longitudinal: 2400 Vpeak 10/700 sec. Products are designed to meet the requirements for supplementary isolation according to IEC950. Common Mode Chokes to reduce common mode ingress from AM Broadcast or HAM Radios are available. See data seet B912 for parts B4001 and B4003.
