DESCRIPTION

P3302 is intended for V.90 and V.92 (56kbps)

modems and other high-speed applications where ultra-low distortion at moderate power levels and very low voiceband frequencies is required at a most competitive price.

P3302 is offered as a more compact internationally safety approved substitute for XM-1025, 2802-B and 671-8079 in existing circuits without changes to matching components.

P3302 exhibits stable core characteristics over its operating temperature range to maximize data

throughput under varying environmental conditions without the need for modem retraining.

P3302 uses patented design and construction methods to achieve excellent signal performance and safety isolation to international standards at truly low cost. P3302 is certified to EN 60950,IEC 950, UL1950 and EN 41003. P3355 is a UL Recognized Component and is supported by a

BABT Certificate of Recognition and an IEC CB Test Certificate.

1. Third harmonic typically exceeds other

harmonics by 10dB.

2. Components are 100% tested at

3.25kVDC.

3. Caution: do not pass DC through windings.

Telephone line current must be diverted using

semiconductor line hold circuit or choke.

4. At signal levels greater than –20dBm, Lp will

increase and Rp will decrease slightly but the

effect is usually favourable to the return loss

characteristic.

SAFETY

ABSOLUTE MAXIMUM RATINGS

(Ratings of components independent of circuit).Constructed in accordance with IEC 950:1991,EN 60950:1992 (BS7002:1992), supplementary insulation, 250Vrms maximum working voltage,flammability class V-0.

There are no special installation requirements (beyond attending to usual PCB track separations)since the integral cover provides supplementary insulation from its external faces to internal core and windings.
