Murata Power Inductors Support 8A-Rated Current Murata has introduced the LQH88P_38 series of power inductors, supporting up to 8A-rated current. The inductors measure 8 x 8mm (3131-size) with a profile of 3.8mm (typical) and are designed for use in DC-DC converters for flat-panel TVs, set-top boxes, recording devices, wireless base stations and other consumer-electronics applications. The LQH88P_38 series is said to possess excellent DC bias current characteristics, saving space for customers by replacing larger-size or higher-profile inductors. The parts are magnetically shielded by ferrite resin to prevent interference with other devices and circuits. Low DC resistance (down to 0.006Ohm) and high-rated current parts are available. The LQH88P_38 series comes in inductance values between 1.0 and 100uH.

Murata Expands Okami Range Of PoL DC/DC Converters Murata Power Solutions has added a miniature 3A, SIP model to its Okami family of non-isolated point-of-load (PoL) DC/DC converters. The OKR-T/3-W12-C provides a solution for designs that require a wide input-voltage range. It offers a high-efficiency PoL solution where board space is limited. Typical applications include datacom routers and servers, industrial equipment such as light-emitting-diode (LED) signage, point-of-sale (PoS) systems and power amplifiers, where the new DC/DC converters are able to provide a cost-efficient way to meet the onboard power needs of ASICs, FPGAs, microprocessors and communications ICs. The new addition to the Okami range has an input-voltage range of 4.5VDC to 14VDC (12VDC nominal) and a programmable output voltage from 0.591VDC to 6.0VDC. Despite overall dimensions of just 10.4mm (0.41in) x 16.5mm (0.65in) x 10.2mm (0.40in), the OKR-T/3-W12-C is said to achieve good thermal derating performance....
