PRODUCT DATA SHEET LOW PROFILE LINE P1165 MATCHING TRANSFORMER Features Applications * Low Profile (11mm) * Telecommunications * Vacuum encapsulated * Modems to V.34 * IEC 950, UL 1950 and EN 60950 certified * Line matching * UL Recognized Component * Portable computers * BABT Certificate of Recognition * Fax/modems * CSA NRTL/C Certificate of Compliance * Instrumentation * High Thermal Stability * Voice DESCRIPTION P1165 is intended for data communications at P1165 also exhibits stable characteristics over its V.32bis (14,400 bits/second) data rates. With careful operating temperature range to maximize data circuit design, P1165 may be used for V.34 throughput under varying environmental applications to 33,600 bits/second or higher. conditions without the need for modem retraining. P1165 is specifically designed to be easily matched P1165 is certified to IEC 950, EN 60950, to both 600ohm and complex impedance telephone EN 41003 and UL1950. P1165 is a UL lines, using a minimum of external components. Recognized Component and is supported by a BABT Certificate of Recognition, a CSA Certificate of Compliance and an IEC CB Test Certificate.
