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

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.
