LCP Series • Miniature Low Cost Toroidal Inductors LCP Series surface mount toroidal inductors are designed for use in applications where energy storage is required for maintenance of a highly stable inductance when a rapid change in load current occurs. These inductors are excellent for filtering high frequency signals while supporting a substantial DC current as well as for AC ripple, switch mode power supplies and for use with DC-DC Converters. Features • Operating frequency to 1 MHz • High energy storage with minimum saturation • High stability from no load to full load • Designed as 1:1 Coupled Inductor (Series or Parallel) or as 1:1 Isolation Transformer • Manufactured in ISO-9001:2000, TS-16949:2002 and ISO-14001:2004 certified Talema facility • Meets lead free reflow level J-STD-020C • Fully RoHS compliant Applications DC-DC Converters • Common Mode Filter • Computer Note Books Pulse Modulation Switching Regulators: Step-up, Step-down, Inverting or dual output • Filtering Battery Powered Equipment Parallel Connected
