Malvern, Pa. Vishay Intertechnology, Inc. has launched two IHLP low-profile, high-current inductors in the 1212 case size. The IHLP-1212AB-11 and IHLP-1212AE-11 are housed in a 3.0 x 3.6-mm footprint with ultra-low profiles of 1.2 mm and 1.5 mm, respectively.
With a high maximum 1-MHz frequency and standard inductance values from 0.22 to 1.0 microhenries, the IHLP-1212AB-11 and IHLP-1212AE-11 inductors are designed for voltage regulator module (VRM) and DC/DC converter applications in end products including next-generation mobile devices, notebooks, desktop computers, graphics cards, portable gaming devices, personal navigation systems, personal multimedia devices, and automotive systems. They also can be used in low-profile, high-current power supplies and point of load (POL) converters as well as distributed power systems and field-programmable gate arrays (FPGAs).
The IHLP-1212AB-11 offers an inductance range from 0.22 to 0.56 microhenries, a saturation current range from 6.7 A to 9.3 A, typical direct current resistance (DCR) from 9.5 to 18.7 milliohms, and maximum DCR from 11.4 to 22.0 milliohms. The IHLP-1212AE-11 offers an inductance range from 0.22 to 1.0 microhenries, a saturation current range from 5.3 A to 9.0 A, typical DCR from 9.5 to 29.5 milliohms, and maximum DCR from 11.4 to 33.0 milliohms.
The inductors handle high transient current spikes without hard saturation, said Vishay. Packaged in a RoHS-compliant, 100 percent lead-free shielded, composite construction that reduces buzz noise to low levels, the 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.
Availability: Samples and production quantities will be available in the first quarter of 2011, with lead times of six weeks for large orders.
