P3356 uses patented design and construction methods to achieve excellent signal performance P3356 has been subjected to relevant and safety isolation to international standards, environmental testing according to IEC 68 and making it the component of choice for high-speed Combined Environmental Reliability Testing data applications throughout the world. P3356 is (CERT) beyond normal operational levels and certified to IEC 60950, UL 60950 and EN 60950. passed all tests, remaining fully functional. P3356 is a UL Recognized Component, and is supported by IEC CB and Demko Certificates. The part is completely lead-free, compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional processing. P3356 has exceptionally flat frequency response from 30Hz to 10kHz, a 3dB bandwidth of over 50kHz and requires only the very simplest of matching to achieve good return loss and transhybrid loss across the voiceband, with very low levels of signal distortion at signal frequencies as low as 150Hz.

Third harmonic typically exceeds other harmonics by 10dB. Fig. 1 2. Components are 100% tested at 3.25kVDC. 3. Caution: do not pass DC through windings. IDEAL Telephone line current must be diverted using L L 1:1 semiconductor line hold circuit or choke. 4. At signal levels greater than 100mV, Lp will increase and Rp will decrease slightly but the effect is usually favourable to the return loss characteristic. 5. Return loss and transhybrid loss can be improved to 30dB in improved matching circuit. The values shown relate to the simplest configuration, Fig. 2. ETALDOC 591/11 Page 2 of 6 December 2005
