Vishay Intertechnology Inc. announced the addition of a new low-profile, high-current inductor series to its line of space- and power-saving inductor solutions for voltage regulator module (VRM) and dc-to-dc converter applications.

According to the press release, the new IHLM-2525CZ-01 series features the lowest DCR/?H for its package size (6.47-by-6.86mm) with a low 3mm profile, and excellent operation over a frequency range up to 5MHz. A molded construction also gives IHLM devices a higher dielectric withstanding voltage that allows for enhanced protection against electrical shock.

Resistant to moisture, salt and chemicals, the new product performs reliably in automotive applications and other extreme environments. Additional end products in which the IHLM series can be used include next-generation mobile communications devices, notebook and desktop computers, and servers. The devices are also suitable for use in fixed-telecom power supplies, including point-of-load and (POL) and distributed power systems.

The IHLM-2525CZ-01 series is specified for saturation currents ranging from 7A to 60A, and for typical DCR values ranging from 1.5 m? to 102 m?. It is designed to handle high transient current spikes without saturation.

With a 100 percent Pb-free composite construction, buzz noise due to magnetostriction is reduced to ultra low levels, said Vishay. The flame retardant encapsulant (UL 94V-0) provides resistance to corrosion and moisture along with a high dielectric rating. The IHLM-2525CZ-01 series offers an operating temperature range of -55C to 125C, and is highly resistant to thermal shock, moisture, mechanical shock and vibration.

Samples and production quantities of the IHLM-2525CZ-01 inductors are already available. Lead time for production quantities is 6 weeks.
