DA101JC-R

Overview

The DA101JC-R is a shielded audio and signal transformer from the DA100J series, manufactured by Murata Power Solutions. It features a single-channel design with a 1:1 turns ratio and surface-mount (SMD-6) termination. The component operates within a frequency range of 50 Hz to 60 Hz and offers an inductance between 1 mH and 2.2 mH. Key electrical specifications include a primary impedance of 110 Ohms, an insulation voltage of 2 kV, and an ET value of 15 Vµs. It functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Provides galvanic isolation with 2 kV insulation voltage for signal integrity
• Shielded construction minimizes electromagnetic interference
• Designed for surface-mount assembly in compact electronic circuits

Applications

• Digital data transmission systems
• Audio signal processing circuits
• Pulse transformer applications requiring isolation

Procurement Notes

Verify the specific suffix against official Murata documentation to confirm functional equivalence, as ordering suffixes may indicate variations in packaging or minor manufacturing updates rather than performance changes. Ensure compatibility with the target PCB footprint and reflow soldering profiles specified in the datasheet. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when a 1:1 isolated pulse transformer is required for low-frequency audio or digital signals. The DA101JC-R is suitable for designs needing robust shielding and wide operating temperature ranges. Consider the SMD-6 package dimensions and the 110 Ohm primary impedance when matching circuit requirements. This model serves as a direct replacement for discontinued variants like the DA101MC-R in compatible designs.

Part Context

This component belongs to the DA100J series of audio transformers, which are engineered for high reliability in consumer and industrial electronics. Murata Power Solutions utilizes advanced winding techniques to ensure consistent magnetic coupling and low leakage inductance. The series is designed to meet stringent environmental standards, including RoHS compliance, ensuring suitability for modern manufacturing processes and global regulatory requirements.

Replacement Considerations

The DA101JC-R is officially suggested by Murata as a substitute for the DA101MC-R.
