DA101MC

Overview

The DA101MC is a digital audio data transmission transformer from the Murata DA100 series, designed for surface-mount applications. It features a single channel with a 1:1 turns ratio and operates within a frequency range of 50 Hz to 60 Hz. The component has an inductance between 1 mH and 2.06 mH, a primary coil impedance of 110 ohms, and an ET value of 15 Vµs. It provides 2 kV isolation voltage and functions at temperatures from 0°C to +70°C. Packaged in an SMD-6 case measuring 9.52 mm by 9.00 mm with a maximum height of 6.35 mm, it supports RoHS3 compliance.

Procurement Notes

Verify component availability as the DA101MC may be subject to limited supply or special order requirements. Confirm that the selected variant meets specific design-in constraints regarding the 1:1 turns ratio and 110 ohm impedance. Ensure compatibility with the required operating temperature range of 0°C to +70°C during final integration testing.

Selection Notes

Select this component for designs requiring precise digital audio signal coupling with minimal distortion. Consider the 15 Vµs ET value when designing transformer-driven circuits to ensure proper signal integrity. Verify that the SMD-6 footprint aligns with the PCB layout constraints and that the 2 kV isolation meets safety standards for the target application environment.

Part Context

The DA101MC belongs to the DA100 series of pulse transformers manufactured by Murata Power Solutions. This series focuses on providing reliable signal transfer for digital audio applications. The component serves as a critical interface element in systems requiring galvanic isolation between audio data sources and receivers while maintaining signal fidelity.

Replacement Considerations

The DA101JC-R is documented as a suggested alternate part number for the DA101MC. Designers should consult official documentation to verify pinout compatibility and electrical parameter equivalence before substituting components in existing designs.
