MIT-3177 MIT-3177 TM A SUMIDA COMPANY Analog Telephony / Modem Couplers DESCRIPTION The REMtech Magnetics MIT-3177 MIT-3177 is a "Dry" Modem Isolation Transformer suitable for up to V.90 (56 kbps) consumer and internet analog modem applications compliant with Domestic safety norms. MIT-3177 MIT-3177 uses less board area than our even lower-cost MIT-3139 MIT-3139 with comparable 56K performance. Impedance match suits typical Lucent-based modem designs. MIT-4177 MIT-4177 is a simple upgrade path from MIT-3177 MIT-3177 to meet upcoming IEC60950 IEC60950 Supplementary worldwide safety. FEATURES PRODUCT COMPLIANCE Suitable for modem speeds up to V.90 (56 kbps). Total Harmonic Distortion rated: -92 dB typ. @ 600 Hz, -10 dBm; and, -83 dB typ. @ 150 Hz, -3 dBm. UL / C-UL recognized file number: E171120 E171120 Insertion Loss rated 2.55 dB typ. @ 1000 Hz. Complies with UL1459 UL1459 safety norms. NOMENCLATURE (Fig. 1) Reflects 600 Ohms on Primary with 301 Ohms Secondary Load. SUPPLIER NAME Very small PCB footprint (16.5 mm x 16.5 mm).
