Vishay releases new IHVR vertical-mount, inductor for high-efficiency converters

Vishay Intertechnology has introduced a new IHVR vertical-mount inductor in the 10.25 mm by 6.4 x 10mm, 4025 case size.

Optimizing inductance and minimizing DCR for increased efficiency in DC/DC converters, the newly designed Vishay Dale IHVR-4025JZ-3Z offers high temperature operation (up to +155° C) for computer, server, telecom, and industrial applications.

Compared to traditional inductors, the compact size and unique vertical-mount design of the device save on board space and allow for more efficient cooling by using air flow.

The device also enables a 50-percent lower DCR down to 0.130 mW (typical) and higher rated current up to 112 A. Its reduced DCR can provide significant savings in energy costs over the life of a server compared to less-efficient solutions. Additionally, its rectangular shape provides better integration with other board components, making it easier for designers to keep PCB trace lengths equal to reduce phase imbalances.

The IHVR-4025JZ-3Z is optimized for energy storage in DC/DC converters up to 5 MHz and high current-filtering applications up to the SRF of the inductor. Applications for the device include desktops and servers, low profile and high-current power supplies, POL converters, and distributed power systems and FPGAs.

In these applications, the inductor offers extremely stable inductance and saturation over the full -40° to +155° C operating temperature range.

Packaged in a 100-percent lead (Pb)-free shielded, composite construction that reduces buzz noise to ultra-low levels, the IHVR-4025JZ-3Z offers high resistance to thermal shock, moisture, and mechanical shock, and handles high transient current spikes without saturation. The device is RoHS-compliant, halogen-free, and Vishay Green.
