DA101MC-R

Overview

The DA101MC-R is a surface-mount pulse transformer from the DA100 series, designed for digital audio data transmission. It features a 1:1 turns ratio and an inductance range of 1 mH to 2.06 mH. The component operates within a temperature range of 0°C to +70°C and provides 2 kV isolation voltage. It utilizes a 6-pin SMD package measuring 9.52 mm in length and 9.52 mm in width, with a maximum height of 6.35 mm. Primary coil impedance is specified at 110 ohms, and it supports frequencies from 50 Hz to 60 Hz.
