DESCRIPTION

P3304 is intended for voice applications where

good distortion at moderate power levels is

required with low insertion loss.

P3304 uses patented design and construction

methods to achieve excellent signal performance

and safety isolation to international standards.

P3304 is certified to IEC 950 and UL 60950. P3304

is a UL Recognized Component, and is supported

by an IEC CB Test Certificate. The part is

completely

lead-free,

compliant

with

RoHS

Directive 2002/95/EC, and suitable for lead-free

and conventional processing.

P3304 has exceptionally flat frequency response

from 100Hz to 10kHz, a 3dB bandwidth of typically

90kHz and requires only the very simplest of

matching to achieve good return loss and

transhybrid loss across the voiceband, with low

levels of signal distortion at signal frequencies as

low as 200Hz.

P3304 has very low leakage inductance and

winding resistances and is designed for use with

3.3V Legerity QSLAC devices. For 5V devices

use P3303 (1:1 ratio).

P3304

has

been

subjected

to

relevant

environmental testing according to IEC 68 and

Combined

Environmental

Testing

(CERT) beyond normal operational levels and

passed all tests, remaining fully functional.
