DESCRIPTION

P3801 is intended for high-speed applications where

low distortion at moderate power levels and very low

voiceband frequencies is required at the most

competitive price. At moderate power levels

(e.g. -10dBm) performance to V.90/V.92 may be

achieved.

P3801 has extended flat frequency response from

30Hz to 4kHz with very low levels of signal distortion

at signal frequencies as low as 150Hz.

P3801 is electrically and mechanically compatible

with

P3034

and

P2001

for

supplementary

insulation 250V working applications, and directly

replaces

9002VF,

671-8236M,

MTLM

2001,

EMIT-2001, and ATS-091/B without changes to

matching components, but with the added benefit

of considerably improved thermal stability. P3801

also offers a drop-in performance upgrade path for

P3800 and P1200.

P3801 uses patented design and construction

methods to achieve excellent signal performance

and safety isolation to international standards. The

part is completely lead-free, compliant with RoHS

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

conventional processing.

P3801 is certified to IEC 60950 and UL 60950.

P3801 is a UL Recognized Component and is

supported by an IEC CB Test Certificate.

P3801 is a rugged lightweight design that 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.
