76253/35ENC

Overview

The Murata Power Solutions 76253/35ENC is an encapsulated power transformer designed for through-hole mounting. It features a single primary winding and a single secondary winding, with a primary voltage rating of 3.3 V and a secondary voltage rating of 5 V. The device has a power rating of 500 mW and a secondary current rating of 100 mA. Key electrical parameters include an inductance of 200 µH and a turn ratio of approximately 1:2.24. The component measures 15 mm in length, 15 mm in width, and 12 mm in height.

Feature Summary

• Encapsulated construction provides environmental protection and mechanical stability for industrial applications.
• Through-hole mounting style ensures secure attachment to printed circuit boards.
• Single primary and single secondary winding configuration supports standard isolation requirements.

Applications

• Industrial medical equipment power supplies
• Data interface isolation circuits
• Pulse transformer applications requiring galvanic isolation

Procurement Notes

Verify the specific manufacturing date code and RoHS compliance status directly with the supplier or manufacturer documentation before procurement. Confirm that the encapsulation type and pinout configuration match the target PCB layout requirements. Ensure the operating temperature range aligns with the intended application environment specifications.

Selection Notes

Select this component when a 3.3 V to 5 V isolated conversion is required with a 500 mW power capacity. The 200 µH inductance value suits applications needing moderate energy storage in pulse transformer designs. Consider the physical dimensions of 15x15x12 mm for board space constraints. Verify compatibility with MAX250/251/253 controller families if used in switching regulator topologies.
