POWER

Coilcraft power inductors are offered in various structure types, sizes and inductance values.

RF inductors: ceramic-core, ferrite-core, air core, conical, broadband bias chokes and RFID coils.

TRANSFORMERS

Power conversion, capacitor charging, gate drive, PoE, current sensing, ultrasonic sensing and data-line isolation.

EMI/CHOKES

EMI common mode chokes and wirewound ferrite beads minimize EMI and are ideal for noise suppression.

DC-DC Optimizer

This complete converter application tool finds the most efficient inductor solutions and analyzes their performance to optimize your Buck, Boost and Buck-boost converters.

Uses measured inductor data for off-the-shelf inductors. Not just theory.
Finds optimal solutions for all inductance values. Not limited to pre-chosen inductance & ripple current
Visualizes I_L waveform, inductor total loss (AC&DC), L vs. I, ΔT vs. current, and more
