Taiyo Yuden’s MDMK4040 power inductor for choke coil applications measures just 4.0 by 4.0 by 1.2 mm, suiting the power circuits of low-profile digital devices like notebook PCs and tablets. By integrating the Taiyo Yuden’s metallic magnetic material technology and advanced process technology, it combines an industry-leading dc bias characteristic with a lower profile size, according to the company. The MDMK4040R2 boasts 2.2-µH inductance and 4500-mA dc bias characteristic, which is 2.7 times better than the preceding NRS4012T 2R2’s 1650-mA dc bias characteristic. Samples cost $1.00 each.
