1 EMIT-2L DESCRIPTION The REMtech Magnetics EMIT-2L is a Dry Encapsulated Modem Isolation Transformer suitable for up to V.9 (6 kbps) consumer and internet analog modem applications compliant with International safety norms. EMIT-2L offers ultra low distortion for superb V.9 (6kbps) modem performance. EMIT-2L improves EMIT-2 to a Low-Profile height with identical characteristics and cost. FEATURES Suitable for modem speeds up to V.9 (6 kbps) at top performance. Total Harmonic Distortion rated -9 db 6 Hz, - dbm and -8 db Hz, - dbm. PRODUCT COMPLIANCE UL / C-UL recognized file number: E72 BSI certificate number(s): 87, 88 BABT certificate of recognition: 9 Insertion Loss rated.9 db 2 Hz. Complies with IEC69 Reinforced safety norms. Matches 6 Ohm and complex impedance telephone lines. Uses minimal external components for impedance matching. Very small PCB footprint (8. mm x 8. mm). Low-Profile (2.6 mm). NOMENCLATURE (Fig. ) REMtech EMIT-2L c 97- MEXICO DATE CODE MADE IN Industry-standard pin configuration.
