Vishay Intertechnology, Inc. (NYSE: VSH) today announced a new IHVR vertical mount inductor with a case size of 10.25 mm x 6.4 mm x 10 mm 4025. Optimized inductance, minimized DCR to improve DC / DC converter efficiency, the newly designed Vishay Dale IHVR-4025JZ-3Z is up to +155 ° C for computer, server, telecom and industrial applications. Provides high temperature operation.
Compared to traditional inductors, the compact size and unique vertical mount design of the device released today saves board space, allows for more efficient cooling using airflow, and DCR. It is 50% lower to 0.130mΩ (standard) and the rated current is higher. Maximum 112A. By reducing the DCR of the device, you can save significant energy costs over the life of the server compared to inefficient solutions. In addition, its rectangular shape provides better integration with other board components, making it easier for designers to maintain equal PCB trace lengths and reduce phase imbalances.
The IHVR-4025JZ-3Z is optimized for energy storage in high current filtering applications up to 5MHz DC / DC converters and inductors up to SRF. Device applications include desktops and servers. Low profile, multi-phase, high current power supply. POL converter; distributed generation system and FPGA. In these applications, the inductor provides very stable inductance and saturation over the operating temperature range of -40 ° C to + 155 ° C.
The IHVR-4025JZ-3Z is packaged in a 100% lead (Pb) -free, shielded composite structure that reduces buzz noise to ultra-low levels. It provides high resistance to thermal shock, moisture and mechanical shock and handles high transient current spikes without saturation. .. This device is RoHS compliant, halogen free and Vishay Green.
