DESCRIPTION

P3410 is intended for V.90 and V.92 (56kbps)
modems and other high-speed applications where
low distortion at high power levels and very low
voiceband frequencies is required at the most
competitive price.

P3410 has extended flat frequency response from
30Hz to 4kHz with very low levels of signal
distortion at signal frequencies as low as 150Hz.

P3410 is electrically and mechanically compatible
with P3146 and P3176, and directly replaces 9010
and EMIT-4020L without changes to matching
components, but with the added benefit of
considerably improved thermal stability.

P3410 uses patented design and construction
methods to achieve excellent signal performance
and safety isolation to international standards at
truly low cost. P3410 is certified to EN 60950,
IEC 950, UL1950 and EN 41003. P3410 is a UL
Recognized Component and is supported by a
BABT Certificate of Recognition and an IEC CB
Test Certificate.

SAFETY

ABSOLUTE MAXIMUM RATINGS

(Ratings of components independent of circuit).

Constructed in accordance with IEC950:1991,
EN60950:1992 (BS7002:1992), supplementary
insulation, 250Vrms maximum working voltage,
flammability class V-0.

There are no special installation requirements
(beyond attending to usual PCB track separations)
since the integral cover provides supplementary
insulation from its external faces to internal core
and windings.
