P1165 is specifically designed to be easily matched to both 600ohm and complex impedance telephone lines, using a minimum of external components. P1165 also exhibits stable characteristics over its operating temperature range to maximize data throughput under varying environmental conditions without the need for modem retraining. P1165 is certified to iec 60950 and ul 60950. P1165 is a ul recognized component and is supported by an iec cb test certificate. the part is completely lead-free, compliant with rohs directive 2002/95/ec, and suitable for lead-free and conventional processing.
