They can be used in DC/DC converters and as signal conditioning or filter inductors. Available standard inductance values range from 0.47 to 330.0 µH. RMS current values range from 19.2 to 0.76 Amperes. Because of their miniature size and rugged construction, UNI-PACs are ideally suited for products requiring higher power per millimeter of PCB space. Such applications include notebook computers, pagers, and a variety of battery powered equipment. Their versatility extends to use in DC/DC converters on all board level products from personal computers to industrial-level VME products. UNI-PACs are engineered for high volume production using automated surface mount technology. Their tape-and-reel packaging accommodates reliable pick-and-place manufacturing, and their construction permits normal exposure to infrared reflow soldering to +240¡C. In addition to the standard inductance values shown, custom inductors are available to meet your exact high volume requirements.
