P2001 is certified to IEC 60950 and UL 60950. P2001 is a UL Recognized Component and is supported by an IEC CB Test Certificate. P2001 meets international safety standards, being vacuum encapsulated and 100% tested to withstand 6.5kV DC. The part is completely lead-free, compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional processing. P2001 is ideal for datacommunications at V.34 (33,600 bits/second) and is a drop-in replacement for industry standard P1200 for circuits to be upgraded for high speed.

Third harmonic typically exceeds other harmonics by 20dB. 2. Components are 100% tested at 6.5kV DC. 3. Caution: do not pass DC through windings. Telephone line current, etc. must be diverted using choke or semiconductor line hold circuit. 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.

Third order intermodulation products 2fa-fb and 2fb-fa are of most importance and are significantly greater than products 2fa+fb and 2fb+fa.
