P5059 is a vacuum encapsulated version of P5056 with the benefits of greater mechanical robustness and breakdown strength. P5059 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. P5059 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. P5059 is certified to IEC 60950, and UL 60950, supplementary insulation for a primary circuit, 250V working. P5059 is a UL Recognized Component and is supported by an IEC CB Test Certificate.

Third harmonic typically exceeds other harmonics by 10dB. 2. Components are 100% tested at 6.5kVDC. 3. Caution: do not pass DC through windings. Telephone line current must be diverted using semiconductor line hold circuit or choke. 4. At signal levels greater than –20dBm, 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.

Good performance is achieved even with the simplest configurations. The implementations assume a low impedance balanced TX drive and a relatively high impedance RX input, as is commonly available, though use with other TX/RX arrangements is straightforward. Note that there are no changes to components on the line side, or in the hybrid, whether 600Ω or complex reference impedance selected, thus assisting country configuration. For complex impedance, the matching circuits derived are suitable for reference impedances of the type 270 + 750//150nF e.g. European CTR21 and 220 + 820//120nF (or 115nF) e.g. Australia, South Africa, etc., and yield similar performance characteristics. For other impedances, please contact Profec Technologies.
