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.
