High-Efficiency Power Inductors suit portable electronics.
Press Release Summary:
Available in EIA 1008 case size footprint of 2.5 x 2.0 mm with max height of 1.0 mm, CKP2520 multilayer chip power inductors include models that offer inductance values from 1.0-4.7 µH, current ratings from 1.4-1.1 A, and RDC values from 0.08-0.15 ohms. Products are suited for dc-dc converter choke coils in ultra-thin portable electronics such as multifunction cell phones, digital cameras, and other battery-powered, portable devices.
Original Press Release:
Taiyo Yuden's New High-Efficiency Power Inductors Offer Higher Current & Lower Resistance for DC-DC Converter Choke Coils
CKP2520 devices offer up to 44% higher current, 35% lower DC resistance vs. equivalent size parts-ideal for DC-DC converter choke coils in ultra-thin portable electronics
SCHAUMBURG, Ill. - January 11, 2008 - TAIYO YUDEN (U.S.A.) INC.'s new CKP2520 multilayer chip power inductors achieve better performance compared to the company's previous industry-leading CKP series parts. The -2R2 part, for example, offers DC resistance and rated current improvements of 35% and 44%, respectively. With an EIA 1008 case size footprint of 2.5 x 2.0mm and a maximum height of only 1.0mm, CKP2520 devices facilitate the design of thinner, higher-performance, multifunction cell phones, digital cameras and other battery-powered ultra-portable electronic equipment.
As shown in the table, series devices offer a range of inductance values and current ratings from 1.0µH to 4.7µH and 1.4A to 1.1A, respectively. Series devices are now available in mass production quantities in the following part numbers:
Part Number Inductance RDC Reduction in RDC Current Rating Increase in Rated Current
@ 1MHz (µH ±20%) (Ohms) vs. Previous Model (A) vs. Previous Model
CKP2520 1R0 1.0 0.08 27.3% 1.4 27.2%
CKP2520 1R5 1.5 0.09 30.1% 1.3 30.0%
CKP2520 2R2 2.2 0.09 35% 1.3 44%
CKP2520 3R3 3.3 0.12 25.0% 1.2 50.0%
CKP2520 4R7 4.7 0.15 25.0% 1.1 57.1%
The continuing miniaturization trend in the feature-rich portable device market is driving the need for smaller, thinner choke coils and multiple DC-DC converters. In response, refinements to TAIYO YUDEN's material science techniques generated component structural improvements that resulted in significant performance increases relative to case size.
Tighter electromagnetic field control and a proprietary new internal-electrode printing process that doubled the thickness of the internal conductor resulted in dramatically lower DC resistance (RDC) and higher current ratings (see table). New additions to the CKP2520 series, now under development, are expected to result in further performance gains in the 1008 and smaller case sizes.
