Multilayer Ferrite Chip Beads minimize noise in less space.

Press Release Summary:

Multilayer Ferrite Chip Beads minimize noise in less space.

Oct 10, 2008 - Supplied in EIA 0201 case size (0.6 x 0.3 x 0.3 mm), BKP0603 series multilayer ferrite chip beads are designed for reducing power circuit noise in portable, battery-powered electronic equipment. Models BKP0603 HS220 and BKP0603 HS330, respectively, offer electrical performance characteristics that include 22 and 33 ohm impedance @ 100 MHz as well as 0.065 and 0.070 ohm RDC values. Maximum rated current for both models is 1.0 A.

Taiyo Yuden's New EIA-0201-Size Multilayer Ferrite Chip Beads Offer 64% Smaller Surface Area Vs. Previous Devices

Press release date: Sep 30, 2008

Leading-edge material science, multilayering and printing technologies result in optimal combination of size & performance for reducing noise in mobile phone power circuits

SCHAUMBURG, Ill. - September 30, 2008 - TAIYO YUDEN (U.S.A.) INC. announces the BKP0603 series of 0.6 x 0.3 x 0.3mm multilayer ferrite chip beads for reducing power circuit noise in cell phones and other portable battery-powered electronic equipment. The models now available in the BKP0603 series offer a 64% smaller device footprint (78% smaller by volume) compared to the company's previous BKP1005 series ferrite chip beads at 1.0 x 0.5 x 0.5mm. For power circuit applications, the BKP0603 offers the optimal combination of size, cost and performance.

The global cell phone market's continuing trend toward smaller, more feature-rich products is driving the need for more IC chips, each with its own power supply circuit to optimize power use and reduce consumption. Because more power supply circuits mean a larger consumer product, smaller components in the DC-DC converters and power supply circuits are needed to minimize end device size as much as possible. However reducing the size of the ferrite chip beads also reduces their rated current and DC resistance (RDC) performance, thus minimizing their ability to handle the higher current levels demanded by the application.

Answering this challenge, TAIYO YUDEN's leading-edge material science capability, coupled with innovative multilayering and printing techniques, resulted in the development of the BKP0603 series of ferrite chip beads in EIA 0201 case size (0.6 x 0.3 x 0.3mm), but with the electrical performance of much larger components. Now being fabricated in production volume quantities, the BKP0603 series presently includes the following part numbers:
Ordering Code   Impedance (ohm) @ 100MHz   RDC (ohm)   Rated Current (A), Max BKP0603 HS220   22              0.065     1.0 BKP0603 HS330   33              0.070     1.0
