TAIYO YUDEN Extend their series of Multilayer Chip Bead Inductors

The multilayer chip bead inductors are ferrite chip beads that address the high frequency noise generated in the power supply and signal circuits of small mobile devices such as smartphones.

The BKP1005EM221 product (with an impedance of 220Ω) improves on the rated current of the company’s conventional product BKP1005HM221 (with an equivalent value) by roughly 11%, from 900mA to 1000mA. The DC resistance has successfully been reduced by about 17%, from 0.180Ω to 0.150Ω, which increases functionality and efficiency of small mobile devices such as smartphones.

TAIYO YUDEN’s lineup has expanded by 20 product numbers. They have added the 6 products to the new EM series for BKP1005, expanded BKP0603 by adding 3 HS series products and the new HM series of 3 products, and have added 8 products as the TS and TM series for BK0603.
Production has manufactured for these products at TAIYO YUDEN (PHILIPPINES), CO., LTD. (Lapulapu City, Cebu) at an output pace of 20 million units per month for BKP1005EM, and 50 million units per month for both BKP0603HS•HM and BK0603TS•TM together. The sample price is $0.05 per unit for each of these.
Technology Background:

Small mobile devices, such as smartphones, require continued miniaturization and multi-functionality. Many circuits are densely packed into these devises and require provisions for EMC. This is especially the case for smartphones. High frequency noise has a greater impact as the currents are increased in power circuits to get higher performance. Ferrite chip beads are required given their capability of eliminating the noise in the higher frequency bands effectively.

To meet these market requirements, TAIYO YUDEN, through more sophisticated layering and pattern printing techniques, has combined both a low DC resistance and a high rated current. The impedance, which is so important in combating the problem of noise, has also been greatly improved in the high frequency band. TAIYO YUDEN’s lineup of chip bead inductors, BKP1005, BKP0603 and BK0603, has been expanded to be best suited for the ever-increasing high performance and efficiency of small mobile devices such as smartphones.

Applications:

To combat noise in the power and signal circuits of small mobile devices, such as smartphones and tablet PCs.
