The new model "SRN3010BTA-330M" optimizes circuit performance through high inductance and improves reliability through the use of bottom-soldered lead wires.

Riverside, California – March 12, 2026 – Bourns, a leading manufacturer of electronic components for power, protection, and sensing solutions, announced the addition of a new high-inductance model to its SRN3010BTA series of semi-shielded power inductors. The new SRN3010BTA-330M model features an inductance of 33µH, enabling efficient current handling. Furthermore, the use of bottom-soldered leads improves mechanical strength and stability, enhancing product reliability.

This power inductor employs a slim, semi-shielded structure with a maximum height of 1 mm, combining the features of both unshielded and shielded inductors. It reduces magnetic field radiation compared to unshielded inductors and is positioned as a more cost-effective alternative to fully shielded ferrite inductors. With a wide operating temperature range of -55°C to +125°C, the SRN3010BTA series is an automotive-grade product compliant with AEC-Q200. The features and design advantages offered by these semi-shielded power inductors make them suitable for power supply applications in automotive systems requiring high reliability, as well as DC-DC converters, consumer electronics, industrial equipment, and communication equipment.

The Bourns® SRN3010BTA-330M semi-shielded power inductor is currently available for purchase, is RoHS compliant (*1), and halogen-free (*2).
