Power inductor for chock coil applications designed for tablets
TAIYO YUDEN CO., LTD. has announced the commercial release of the new “MDMK4040” (4.0 x 4.0 x 1.2mm, the maximum height value), following the commercialization of a 4mm square metal core SMD power inductor “MCOIL” series that uses metallic magnetic materials.
This product is a power inductor for choke coil applications aimed at the power circuits of low profile digital devices, such as Note PCs, as typified by the tablet PC and Ultrabook device, with their continuing trend for small size, low profile and high performance. Through the integration of TAIYO YUDEN’s own metallic magnetic material technology and advanced process technology, this is a super high-end product which combines both an industry leading DC bias characteristic with a smaller, lower profile size. “MDMK4040T2R2” (with an inductance value of 2.2μH and a DC bias characteristic of 4500mA), compared to the company’s conventional product “NRS4012T 2R2” of the same inductance value (with a DC bias characteristic of 1650mA), represents an improvement in the DC bias characteristic of approximately 2.7 times, which is a great contribution to the higher performance of the device.
Production commenced in July 2012, at the company’s Nakanojo plant (Nakanojo-machi, Agatsuma-gun, Gunma prefecture) at an output pace of 10 million units per month. The sample price is $1.00 each.
