Taiyo Yuden(U.S.A.), Inc. has released two new achievements in its expanding series of high-frequency multilayer chip inductors providing high-inductance (HK series) and high-Q factor (HKQ series) performance characteristics.

While the HK series offers a 100 nH-rated chip inductor in an EIA 0201 case size, the HKQ series includes a new line of 0201 high-Q chip inductors (1-10 nH) with 30% higher Q values than previous series devices, relative to case size. These developments will facilitate higher-density PCB mounting and smaller end devices by greatly reducing the size of critical noise-suppression components in cell phone RF circuits, power amplifiers, voltage-controlled oscillators and other choke-coil applications.

Further, the majority of existing 0402 and larger devices used in choke-coil applications can now be down-sized to 0201 case size components—providing minimum circuit board real estate, a savings of 64% area and 78% volume per component. All HK and HKQ series devices improve end-device manufacturability by providing non-polarized electrodes that allow mounting in any orientation on the circuit board.

Available in production volume, the 100 nH device provides almost 79% higher inductance than the industry’s previous top-rated 0201 chip—56 nH. The high-inductance (HK) chip inductor series currently provides a wide inductance range of 1 nH (250 mA) to 100 nH (40 mA). The latest additions to the high-inductance (HK) series include:

Also available in volume, the company’s high-Q (HKQ) series chip inductors in 0201 case size provide a 30% higher Q value—relative to case size—than comparably rated devices in 0402 (1.0 mm x 0.5 mm x 0.5 mm), the current industry norm. Key specifications in the HKQ series—with models from 1 nH (250 mA) to 10 nH (150 mA)—include:
