Z1656

The Z1656 is designed as one kind of 56kBit modems transformers which has necessitated the design of Line Isolation Transformers that are capable of
providing extremely low distortion across a wide frequency range.OEP offers the user a number of different variants, with industry standard pin outs, from which to select a device to satisfy particular technical and commercial considerations.With the exception of the SMD PC Card device, P/N PC3456 these transformers are designed for conventional PCB mounting.The epoxy resin encapsulation provides reinforced insulation to meet the requirements of EN60950 / EN41003 and BABT approvals. Double section bobbins are used except for the Z1656/4 and PC3456 versions which are concentrically wound on
single section bobbins for closer coupling of the windings thus providing extremely low leakage inductance figures.

The characteristics of the Z1656 are:(1)size(mm):18x18x13 encapsulated;(2)return loss (dB) 200-4kHz:>20;(3)insertion loss (dB) @1kHz:0.80;(4)frequency response (dB):100-4kHz +/- 0.1dB;(5)harmonic distortion:400Hz (dB) typical:-100 and 600Hz (dB) typical:-93;(6)isolation volts RMS:3750;(7)leakage induct.(mH):19;(8)BABT approved number:CR/0125.
