NOTES:
Temperature range: -40°C to +80°C. Insertion loss increases by up to 1 dB at the extreme temperatures. Impedance 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 µsec. 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 sheet
B912
