78613/3C

Overview

The Murata Power Solutions Inc. 78613/3C is a general-purpose pulse transformer designed for through-hole mounting. It features a turns ratio of 1CT:1 and an inductance of 200 µH. The component has a voltage-time (Et) rating of 20 Vµs. Physical dimensions are 9.52 mm in length, 9 mm in width, and 6.35 mm in height. It operates within a temperature range of 0°C to +70°C.

Feature Summary

• Provides galvanic isolation with a center-tapped primary configuration.

Applications

• Gate drive circuits
• Signal isolation
• Pulse transmission

Procurement Notes

Verify the specific package type and pinout against the official datasheet before integration. Confirm that the operating temperature range meets system requirements. Ensure the Et rating supports the intended signal frequency and amplitude. Check for RoHS compliance status if required by local regulations.

Selection Notes

Select this component when a center-tapped primary is required for push-pull or half-bridge topologies. The 200 µH inductance suits moderate frequency applications. Verify that the physical footprint fits the PCB layout constraints. Consider thermal management if operating near the upper temperature limit.
