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 Reliability Testing
(CERT) beyond normal operational levels and
passed all tests, remaining fully functional.
