LC1-0.30-220

LC Series • Miniature Low Cost Toroidal Inductors LC 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 • Pick and place compatible • Designed as 1:1 Coupled Inductor (Series or Parallel) or as 1:1 Isolation Transformer • Manufactured in an ISO-9001:2000, TS-16949:2002 and ISO-14001:2004 certified Talema facility • Meets lead free reflow level J-STD-020C • Fully RoHS compliant Electrical Specifications at 25°C Test frequency: Inductance measured @ 10kHz/10mV Test Voltage between windings: 500Vrms Operating Temperature: -40°C to +125°C Climatic category: IEC68-1 40/125/56 Parallel Connected Part Number Full Load Current (ADC) 3.00 2.10 1.40 1.10 0.92 0.76 0.64 0.54 0.44 0.36 0.30 LO (µH) ±15% N o L o ad 2.2 4.7 10 15 22 33 47 68 100 150 220 DCR mOhm 9 16 37 58 86 133 205 307 376 719 866 Full Load Current (ADC) 1.50 1.05 0.70 0.55 0.46 0.38 0.32 0.27 0.22 0.18 0.15 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 Series Connected LO (µH) ±15% N o L o ad 8.8 18.8 40 60 88 132 188 272 400 600 880 DCR mOhm 36 64 148 232 344 532 820 1228 1504 2876 3464 Energy Storage (µJ) 2 7.0 7.2 7.2 7.0 7.1 7.2 7.1 7.2 7.2 7.2 7.3 LC1-3.00-2.2 LC1-2.10-4.7 LC1-1.40-10 LC1 1.10-15 LC1-0.92-22 LC1-0.76-33 LC1-0.64-47 LC1-0.54-68 LC1-0.44-100 LC1-0.36-150 LC1-0.30-220 Talema's engineering staff can assist in the design of other inductance values and sizes. Note: The µJoule rating (½LI²) is the ability of the inductor to store energy.
