Vishay IHLP 1212 Inductor – Vishay Intertechnology, Inc. (NYSE: VSH) introduced a new IHLP® low profile, high current inductor in the compact 1212 case size. For space-constrained commercial applications, the Vishay Dale IHLP1212-EZ-1Z offers comparable electrical performance to larger devices in a compact 3.0 mm x 3.0 mm footprint with three profile options: 1.2 mm, 1.5 mm, and 2.0 mm.
The device released is optimized for energy storage in low profile DC/DC converters for PMICs, power line noise suppression, and filtering. Applications for the inductor include industrial drives and tools; home and building control; computers and computer peripherals; consumer entertainment and healthcare devices; telecom equipment; and medical instrumentation.
Delivering high efficiency for these applications, the IHLP1212-EZ-1Z offers typical DCR from 8.6 mΩ to 50.4 mΩ and a wide range of inductance values from 0.22 µH to 3.3 µH. The inductor provides rated current to 14.3 A, operates over a temperature range of -55 °C to +125 °C, and handles high transient current spikes without saturation.
Offering improved performance over ferrite-based technologies, the IHLP1212-EZ-1Z features a robust powdered iron body that completely encapsulates its windings — eliminating air gaps and magnetically shielding against crosstalk to nearby components — while its soft saturation curve provides stability across the entire operating temperature and rated current ranges.
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 device is RoHS-compliant, halogen-free, and Vishay Green.
