Vertical-mount inductor saves space in 4025 case

Available in a 4025 case, measuring 10.25 x 6.4 x 10mm, the Vishay Dale IHVR-4025JZ-3Z inductor has been designed with a vertical-mount configuration to save space. Vishay Intertechnology says that the Vishay Dale device reduces DC resistance (DCR) down to 0.130mOhm (typical).

It is also claimed to optimise inductor for increased efficiency in DC/DC converters. Temperature operation is up to +155 degrees C for computer, server, telecomms and industrial applications.

Compared to traditional inductors, the compact size and unique vertical-mount design of the IHVR-4025JZ-3Z saves board space and allows for more efficient cooling by using air flow while enabling 50 per cent lower DCR and higher rated current up to 112A. The device’s reduced DCR can provide significant savings in energy costs over the life of a server, says the company. The 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 vertical-mount inductor is optimised for energy storage in DC/DC converters up to 5MHz and high current filtering applications up to the self resonant frequency (SRF) of the inductor.

Applications include desktops and servers, low profile, multi-phase, high current power supplies, PoL converters, distributed power systems and FPGAs. The inductor offers stable inductance and saturation over the -40 to +155 degrees C operating temperature range, confirms Vishay.

Packaged in a 100 per cent lead (Pb)-free shielded, composite construction that reduces buzz noise, 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 and halogen-free.

Samples and production quantities of the IHVR-4025JZ-3Z are available now, with lead times of 12 weeks.

Vishay claims to manufacture one of the world’s largest portfolios of discrete semiconductors and passive electronic components for designs in the automotive, industrial, computing, consumer, telecommunications, military, aerospace and medical markets.
