VDSL TRANSFORMERS Excellent return loss and balance Surface mount or through hole package Supplementary Insulation Electrical Specifications @ 25°C — Operating Temperature -40°C to +85°C Part Number Turns Ratio B4006 (THT) 1:1 B4023 (THT) 1:1CT B4004 (SMT) 1CS:1CS Insertion Loss (dB MAX) Return Loss (dB MIN) 200 kHz to 400 kHz: 0.75 200 kHz to 18 MHz: 20 400 kHz to 30 MHz: 0.50 18 MHz to 30 MHz: 14 200 kHz to 20 MHz: 0.50 200 kHz to 18 MHz: 17 20 MHz to 30 MHz: 0.75 18 MHz to 30 MHz: 13 200 kHz: 10 400 kHz: 16 4 MHz: 16 11 MHz: 10 200 kHz to 11 MHz: 1.00 Longitudinal Balance (dB TYP) 200 kHz: 60 11 MHz: 50 100 MHz: 40 200 kHz: 60 11 MHz: 50 100 MHz: 40 200 kHz: 50 2 MHz: 40 11 MHz: 40 Isolation Voltage (Vrms) 3000 3000 1500 NOTES: Temperature range: -40°C to +80°C. Insertion loss increases by up to 1 dB at the extreme temperatures. Impedance for test: 100 W or 135 W. 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 for parts B4001 and B4003.
