High-Temp Inductor from New Yorker Electronics Offers Higher Current Density for Multi-phase Power Supplies

23 August 2018

New Yorker Electronics has just released the first device in a new IHSR series of high-temperature commercial inductors. Designed for multi-phase, high current power supplies and filters in computer, industrial and telecom applications, the Vishay Dale IHSR-4040DZ-51 offers a 50 percent reduction in DCR over typical power inductors. It also demonstrates a 20 percent or greater profile reduction over similar ferrite products. In addition, the inductor boasts an unprecedented standard DCR tolerance of 5 percent, with 3 percent available for more accurate current sensing.

With a frequency range up to 5MHz, the recently released device is optimized for energy storage in DC/DC Source: New Yorker ElectronicsSource: New Yorker Electronicsconverters and high current filtering up to the self-resonant frequency (SRF) of the inductor. Applications include notebooks, desktop PCs, and servers; low profile, high current power supplies and filters; and DC/DC converters for distributed power systems.

The IHSR-4040DZ-51’s low typical DCR of 0.520mΩ and inductance of 0.130µH allow for higher current density than competing technologies, while its 4mm profile enables slimmer end products. The inductor offers high-temperature operation to +155°C, rated current to 92A, and handles high transient current spikes without saturation. The device is available in the 10mm x 10mm 4040 case size; additional case sizes will be offered in the future.

Packaged in a 100 percent lead-free shielded, composite construction that reduces buzz noise to ultra low levels, the inductor offers high resistance to thermal shock, moisture and mechanical shock. The IHSR-4040DZ-51 is RoHS-compliant, halogen-free and Vishay Green.

New Yorker Electronics is a franchise distributor for Vishay Dale and carries the full line of Vishay Super 12 Featured Products as well as its complete line of discrete semiconductors (diodes, MOSFETs and infrared optoelectronics) and passive electronic components (resistors, inductors and capacitors).
