Power inductors offer low magnetic radiation

Bourns, Inc. has released low low-profile, small footprint SMD power inductors designed for DC/DC converters in mobile electronics applications.

"The latest devices offer the advantages of wirewound construction, and are designed with an iron powder core that features high saturation current and shielded construction for low magnetic radiation," said Guido Zehnder, product manager at Bourns.

The new power inductor models, designated SRP2010 and SRP2512, feature inductance values ranging from 0.22μH to 2.2μH, with Irms up to 4.5A and up to 6.5A saturation current. SRP2010 is housed in a 2.0mmx1.6mmx1.0mm package, while SRP2512 measures 2.5mmx2.0mmx1.2mm. Their sizes make them ideal for a broad range of ultra-thin electronic applications including smartphones, tablets and data storage devices.

Zehnder said that both devices satisfy the demand of mobile electronics designers for smaller and thinner DC/DC converter solutions that must also meet their high current requirements.

SRP2010 is available at $0.22 each in 5,000-unit quantities.
