Power Factor Correction Chokes:

We offer Power Factor Correction Chokes (PFC Chokes) from Coilcraft and Würth Elektronik.PFC Chokes allow voltage and current waveforms to be in phase, maximizing the power in switch mode power supply circuits. Their highly efficient properties make them some of the most cost-effective products available.The advantages of PFC Chokes include:

1. Reduced Harmonic Currents — PFC Chokes can smooth out the AC waveform, reducing harmonics, and allowing the circuit to meet emissions regulations.
2. Improved Efficiency — When the power factor is increased (voltage and current wave forms in phase) more of the available power is usable, making the circuit more efficient.
3. Reduced Size — Since less power is wasted, and lost in the form of heat, components can be smaller, saving size and cost.

Our range of Würth Elektronik Midcom WE-PFC Power Factor Correction Chokes offers compatibility with standard off-the-shelf components. These chokes can be used for active PFC designs of power supplies up to 250W. They are suggested in the reference design of leading IC manufacturers like ON Semiconductor for their NCP1606B and MC33262 devices. Typical applications for WE-PFC chokes are in AC/DC power supplies with active PFC often found in the lighting industry.Our coils from Coilcraft were developed specifically for use with the ON Semiconductor NCP1653 Power Factor Controller (PFC) for driving continuous conduction mode step-up pre-converters.
