TTC-5027

Overview

The Tamura TTC-5027 is a surface-mount audio transformer designed for data and audio coupling applications. It features a 1:1 turns ratio with primary and secondary impedances of 30k ohms each. The device offers an isolation voltage of 1875VRMS at 1 second and operates within a temperature range of -20°C to 85°C. Primary and secondary DC resistances are both 165 ohms. The component measures 12.50mm x 9.60mm x 7.60mm maximum height and utilizes flat lead termination.

Feature Summary

Surface mount construction with flat lead termination
High isolation voltage rating of 1875VRMS
Symmetrical 30k ohm impedance configuration
Compliant with UL60950 and EN60950 safety standards

Applications

Audio signal coupling in electronic circuits
Data transmission line interfacing
Telecommunications equipment signal processing
Industrial control system audio interfaces

Procurement Notes

Verify the specific ordering suffix, such as TR or CT, to ensure correct packaging format, as the base part number may correspond to different reel quantities. Confirm RoHS compliance status and MSL level requirements against project specifications. Cross-reference manufacturer datasheets for exact dimensional tolerances and thermal handling guidelines during assembly processes.

Selection Notes

Select this component when high impedance matching is required for audio or data lines. Ensure PCB layout accommodates the 12.50mm length and 7.60mm height constraints. Verify that the operating environment stays within the specified -20°C to 85°C range. Check isolation requirements against the 1875VRMS rating for safety compliance.

Part Context

Part of the Tamura TTC series of audio transformers. Designed for SMD assembly. Alternative part numbers include MT7211TR and MT7211CT-NDR. Manufactured by Tamura Corporation. Available in tape and reel packaging for automated placement.

Replacement Considerations

TTC-5027-1 is listed as a related variant. Verify electrical parameters and pinout compatibility before substitution. Consult official documentation for any functional differences between the base model and suffix variants.
