LC1-3.00-2.2 Datasheet, PDF (1/1 Pages) Nuvotem Talema – Miniature Low Cost Toroidal Inductors

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
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
