P3303
DESCRIPTION
P3303 is intended for voice and low speed data
applications where good distortion at moderate
power levels is required with low insertion loss.
P3303 uses patented design and construction
methods to achieve excellent signal performance
and safety isolation to international standards,
making it the component of choice for low loss
voice and data applications throughout the world.
P3303 is certified to IEC 60950 and UL 60950.
P3303 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.
P3303 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.
P3303 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.
P3303 has very low leakage inductance and
winding resistances and is designed for use with
AMD QSLAC devices.
