LC -Mini Toroidal Chokes 1:1, Low cost

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 ISO-9001 approved facility
  • Test voltage between windings: 500 Vrms
  • Operating temperature range: -40°C to 85°C
  • Test frequency: Inductance measured @ 10kHz/10 mV
  

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

We can assist in the design of other inductance values and sizes.

Notes:
1. L(µH): Inductance is tested at 10 mV and 10kHz.
2. The µJoule rating (1⁄2LI2) is the ability of the inductor to store energy.
