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 them without changes to matching components, but with the added benefit of improved thermal stability. P3410 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. P3410 is certified to iec 60950 and ul 60950. P3410 is a ul recognized component and is supported by an iec cb test certificate. P3410 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. patented
