New Low-Profile, High-Current Vishay Inductors Feature 1.19 mm Height Profile, Handle Up To 500 mA: An Industry First
MALVERN, PENNSYLVANIA-January 26, 2001-A new pair of surface-mount inductors combining low-profile packaging, high current handling, and robust energy storage capabilities has been announced by Vishay Intertechnology, Inc. (NYSE: VSH). Small and lightweight, the new Vishay Dale ILS-2515 devices are targeted at portable electronics applications, including circuitry for PC Cards, TFT displays, and LCDs in notebook computers, cell phones, and other handheld information appliances.
The ILS-2515 inductors are the first such products on the market to combine a rated dc current of 500 mA and a package measuring just 0.15 in. (3.8 mm) by 0.25 in. (6.35 mm) with a remarkably slender 0.047 in. (1.19 mm) height profile, enabling the design of slimmer dc-to-dc conversion circuits. With a high-efficiency rated Q of up to 55 at 7 MHz, the ILS-2515 is offered in 4.7-μH (ILS-2515) and 10-μH versions with respective dc resistance of 0.58 Ω. and 0.95 Ω. Inductance tolerance for both devices is ±20%.
Featuring monolithic, ferrite construction, the self-shielding ILS-2515 features terminals designed for maximum trace EMI, enabling more compact designs.
Today's customer for notebook computers, cell phones, and other information appliances want a product that is not only small but as thin as possible. Low-profile inductors that can meet the current demands of these applications are key to making handheld electronics that are slim enough to fit easily into a pocket while maximizing the energy delivered by a smaller battery pack.
Packaged in tape and reel form for high-speed assembly, samples and production quantities of the new ILS-2515 inductors are available now, with lead times of four to six weeks for larger orders.
