Apr.17, 2012

Small and thin, realizing the direct-current bias performance on top level in the industry (※1) Announcing the release of “the multilayer power inductor” Suitable for DC/DC converter circuits used in smart phones, DSCs etc.

  • (※1) Our investigation of the multilayer power inductor as of April 16, 2012

April 16, 2012, Osaka, Japan-Industrial Devices Company, Panasonic Corporation has succeeded in commercializing “ the multilayer power inductor “ suitable for DC/DC converter circuits of small electronic devices including smart phones and DSC. Newly developed power inductors have the direct-current bias performance on top level in the industry (※1) and feature thin, small in size, and large current in capacity

Product name Multilayer power inductor
Series name ELG series
Production start April 2012
Sample price 8 yen/piece and more
Production capacity 5 million pieces/month

As DC/DC converter circuits having the better conversion factor have been used in power supply of small electronic devices, such as smart phones and DSCs, the converter circuits have become to be smaller and larger in current capacity. Power inductors to be installed have been required to be smaller, thinner as well as larger in current capacity. To meet the market demand, Industrial Devices Company, Panasonic Corporation has succeeded in developing “ the multilayer power inductor “ featuring small, thin, as well as large current in capacity, and also achieving the direct-current bias performance on top level in the industry. Although we have been producing the winding types of power inductors, we would like to expand our product line up by commercializing the multilayer power inductor, and will provide smart phone and DSC markets with them.

Features

1. Direct-current bias performance on top level in the industry, realizing the large current in capacity
Direct-current bias performance on top level in the industry: 2.5 μH, ( current: 0.5 A) (※2)
2. Small and thin, contributing to downsizing electronic devices
Dimensions: L 2.0 mm × W 1.25 mm × T 1.0 mm max.
・High temperature properties: Life; 1000 hours at 85 ℃
・Heat shock properties: from -40 ℃ to 85 ℃ (1000 cycles)
  • (※2) In case of the product of inductance 4.7 μH with 2012 size

Applications

DC/DC converter circuits of small electronic devices, such as smart phones and DSCs
