Jensen Transformers JT-123-FLPCH Line Output Transformer
1:1 or 1:2 ratio with quadfilar windings, 50% nickel laminations
Jensen Transformers JT-123-FLPCH Lline Output Transformer
The Jensen Transformers JT-123-FLPCH Line Output transformers allow any output stage circuit topology, whether balanced or unbalanced, to drive any equipment input, whether balanced or unbalanced, without regard to special connection rules or specific cables. Due to the isolation they afford, hum can be substantially reduced.
It may also be worth mentioning that JT-123-FLCF is a direct replacement for JT-112-LCF - the only change is the part number. JT-123-FLPCH is electrically identical to both of the above, but with PC board mount instead of wire leads.
Here are some key specs:
- Impedance ratio: 600:600
- Turns ratio: 1:1
- Maximum 20 Hz input: +20 dBu
- THD @ 20 Hz: 0.025 %
- Frequency Response: 20 - 20 KHz, -0.04 / +0.04 dB
- See spec sheet for additional details
The JT-123-FLPCH is backed by the manufacturer's comprehensive one-year warranty, and has a remarkable 20-year warranty on the transformer device itself.
Jensen Transformers' Description
Jensen Transformers JT-123-FLPCH Line Output Transformer
1:1 or 1:2 ratio with quadfilar windings, 50% nickel laminations, +21dBu @ 20Hz. PC board mount
- Distortion 0.025% typ at 20 Hz and +4 dBu output level
- Wide bandwidth: -3 dB at 0.07 Hz and 270 kHz
- Drives 600 Ω loads to levels up to +20 dBu at 20 Hz
- Excellent time domain performance: DLP 0.6° typ 20 Hz to 20 kHz
- Loading loss only 1.5 dB when driving 600 Ω load
This transformer is designed for high performance output stages. The 50% nickel alloy core gives it excellent distortion and level handling. It may optionally be configured for 1:2 step-up or 2:1 step-down operation. Driving signals should be free of DC and source impedance kept as low as possible.
