SRF0703HA-101M

Arrays, Signal Transformers Overview

The Bourns SRF0703HA-101M is an automotive-grade, dual-winding shielded power inductor from the SRF0703HA series. It features a ferrite core and surface-mount construction with dimensions of 7.6 mm x 7.6 mm x 3.4 mm. The component provides an inductance of 100 µH ±20% in parallel configuration and 397.6 µH in series. It supports a rated current of 0.73 A (parallel) and 0.367 A (series), with maximum DC resistances of 715 mΩ and 2.64 Ω respectively. It operates between -55°C and +150°C and holds AEC-Q200 certification.

Arrays, Signal Transformers Feature Summary

• Automotive-grade reliability certified to AEC-Q200 standards
• Dual-winding architecture supporting parallel, series, and transformer configurations
• Shielded design utilizing a ferrite core to minimize electromagnetic interference

Arrays, Signal Transformers Applications

• Automotive power supply circuits
• DC-DC converter modules
• Isolated power conversion stages

Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'HA' to confirm automotive qualification and AEC-Q200 compliance, as standard SRF0703 variants lack this rating. Confirm package availability matches production requirements. Check RoHS status details on official documentation for environmental compliance verification before finalizing procurement specifications.

Arrays, Signal Transformers Selection Notes

Select this component when automotive durability and high-temperature operation up to 150°C are required. The dual-winding capability allows flexible circuit topologies including isolated converters. Ensure the 0.73 A parallel current rating meets load demands. Compare against non-HA variants if automotive certification is unnecessary to optimize cost.

Arrays, Signal Transformers Part Context

This part belongs to the Bourns SRF0703HA series of coupled inductors. It shares physical dimensions with the standard SRF0703 series but differs in material composition and qualification. The HA designation specifically indicates enhanced thermal stability and automotive-grade manufacturing processes suitable for harsh vehicle environments.

Arrays, Signal Transformers Replacement Considerations

SRF0703-101M serves as a non-automotive alternative within the same footprint. Verify that the lower temperature range (-40°C to 125°C) and lack of AEC-Q200 certification meet system requirements before substitution.
