Mag Amp Toroids – G642X Series
This product is not RoHS-compliant. Contact Coilcraft
for current status or possible alternatives.
These low cost saturable reactor (mag amp) coils are
designed to regulate switching power supplies operating
at frequencies from 20 kHz to over 100 kHz.
In multi-output circuits requiring tight crossregulation,
mag amp control is simple and more cost-effective than
adding conventional linear voltage regulators to each
output. Mag amps are also particularly advantageous
where load current exceeds 1 or 2 amps, because of
their efficiency and low heat dissipation.
Coilcraft Designer’s Kit No. P206 contains samples of
all values shown. To order, please contact Coilcraft or

Advantages
• Higher efficiency than linear regulators, especially at higher currents
• Simple cross-regulation of multi-output supplies
• Lower EMI
• Frequency range of 20 kHz to over 100 kHz
• Standardized construction for maximum economy
