PRODUCT DATA SHEET LINE MATCHING TRANSFORMER P1200 Features Applications Industry Standard V.32bis and V.22bis modems Lead free (Pb-free) Line Matching RoHS compliant Set Top Boxes 12.6mm (0.5 ) seated height Instrumentation Vacuum encapsulated Portable computers IEC 60950 and UL 60950 Certified Fax / modems UL Recognized Component Voice DESCRIPTION P1200 is the transformer of choice in medium-speed P1200 is specifically designed to be easily applications where good performance in a robust matched to both 600 ohm and complex resin encapsulated package is required at a most impedance telephone lines, using a minimum of competitive price. external components. P1200 meets international safety standards, being P1200 is certified to IEC 60950 and UL60950. vacuum encapsulated and 100% tested to P1200 is a UL Recognized Component and is withstand 6.5kV DC. The part is completely supported an IEC CB Test Certificate. lead-free, compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional processing. P1200 is ideal for voice telecommunications applications and for data communications to V.32 bis (14,400 bits/second) data rates. With care, P1200 may be used for V.34 applications to 28,800 bits/second.
