Stackpole Electronics Inc. has extended its power inductor product offering with several product line expansions. Among those additions include the CPS series of shielded power inductors with high current handling in a small package, and several additional sizes for the VLH and PDRH series.

The CPS1008 is a compact, shielded power inductor that measures 3.81mm2 x 2.54mm high, and is capable of handling DC currents up to 2A. Because of its small size the CPS series is suitable for portable devices, laptops, PDAs, and other handheld wireless communication devices.

The variable lens holder series is offered in shielded and unshielded configurations and adds three small sizes to its offering such as 201609E, 201514 and 322515. These new sizes offer high quality at high frequencies, making them suitable for high-frequency communications devices that require higher current than the typical wirewound RF inductor can provide. The inductance range, current handling and DC resistance vary widely by size. The larger VLH sizes are optimized for high current and low DC resistance making them a suitable choice as a choke coil for DC power supply circuitry.

The PDRH series adds six new sizesthe 0301, 0302, 0303, 0501, 0502 and 0503to the existing 0418 size. The PDRH is a low-profile shielded power inductor with the electrode attached directly to the ferrite core. This yields a part capable of high-saturation current handling up to 4.82A and inductance values up to 10mH. The PDRH targets laptops, LCD displays and other types of terminals, and all types of small-sized DC/DC converters.
