VISHAY Intertechnology has announced four new additions to the IHLP family of power inductors, which now includes the industry's first such devices available with a 5% DCR tolerance for current-sensing applications. They are available from Braemac .
These new series have been tested and approved by major IC manufacturers and several other customers. With the lowest DCR/µH for their respective package sizes, the new IHLP-2525CZ-06, IHLP-2525CZ-07, IHLP-5050CE-06, and IHLP-5050CE-07 offer high-performing, space and power-saving solutions for voltage regulator module (VRM) and dc-to-dc converter applications in end products.
New devices in the IHLP-2525CZ series feature compact dimensions of 6.47mm by 6.86mm with the lowest height profile - just 3mm - available in this package footprint.
The IHLP-2525CZ-06 and IHLP-2525CZ-07 are specified for saturation currents ranging from 7A to 60A and for typical DCR values ranging from 1.4mΩ to 97.7mΩ. Available in a 12.9mm by 13.2mm package with a 3.5mm height profile, the IHLP-5050CE-06 and IHLP-5050CE-07 are specified for saturation currents from 14A to 51A and for a DCR range of 1.85mΩ to 30.86mΩ.
The IHLP-2525CZ-06 and IHLP-5050CE-06 offer 10% DCR tolerance, while the IHLP-2525CZ-07 and IHLP-5050CE-07 provide an industry-first 5% DCR tolerance. The inductance range for IHLP-2525CZ-06 and IHLP-2525CZ-07 is 0.10µH to 10µH. The IHLP-5050CE-06 and IHLP-5050CE-07 have an inductance range from 0.60µH to 10µH. These new power inductors from Vishay Dale handle high transient current spikes without saturation and operate over a frequency range up to 5MHz.
Packaged in a 100% lead-free, shielded, composite construction that reduces buzz noise, the new devices are specified for an operating temperature range of -55°C to +125°C with high resistance to thermal shock, moisture, mechanical shock, and vibration.
Because these devices include a current-sensing function, they allow designers to replace multiple parts with a single inductor, thereby lowering component count and costs. Samples and production quantities of the new power inductors are available now. Lead time for production quantities is 6 to 11 weeks.
