New Yorker Electronics has released the first device in a new IHSR series of high-temperature commercial inductors. The Vishay Dale IHSR-4040DZ-51 is designed for multi-phase, high current power supplies and filters in the computer, industrial and telecom applications and offers a 50% reduction in DCR over typical power inductors.
It also demonstrates a 20% or greater profile reduction over similar ferrite products. In addition, the inductor boasts an unprecedented standard DCR tolerance of 5%, with 3% available for more accurate current sensing.
With a frequency range up to 5MHz, the Vishay Dale IHSR-4040DZ-51 is optimized for energy storage in DC/DC converters 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 available from New Yorker Electronic, 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 Key Features & Benefits of Vishay’s latest device include:
- High-temperature rating, up to 155°C
- Shielded construction
- Excellent DC/DC energy storage up to 5 MHz.
- Lowest DCR/μH, in this package size
- Handles high transient current spikes without saturation
- Ultra low buzz noise, due to composite construction
- Patent pending
The inductor ofers 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% lead (Pb)-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.
The Key Applications of the Vishay IHSR-4040DZ-51 include:
• Notebook / desktop / server applications
• High current POL converters
• Low profile, high current power supplies
• High current, high-frequency multi-phase DC/DC Converters
• DC/DC converters in distributed power systems
