Explore VOOHU common mode chokes for power and signal lines, and molded power inductors and high current power bead inductors for DC-DC power stages. Choose a product family below to review selection requirements, or contact our team for samples and quotations.
Explore Inductor Families
Choose a family by circuit function, then review model specifications and datasheets.
Power Line Common Mode Chokes
Chokes for suppressing common mode noise on power supply lines. Review common mode impedance, rated current, DC resistance and size when selecting a model.
Signal Line Common Mode Chokes
Chokes for suppressing common mode noise on differential pairs with minimal effect on the differential signal. Check common mode impedance, rated current and the impact on signal integrity.
Molded Power Inductors
Power inductors for supply circuits, with the winding enclosed in a magnetic compound. Review inductance, DC resistance, RMS current and saturation current when selecting a model.
High Current Power Bead Inductors
Nanohenry-level, high-current inductors for the power stages of multiphase buck converters. Check initial inductance, tolerance, saturation current and heating current.
Which Inductor Does Your Circuit Need?
Need help identifying the right family? Contact our team →Common mode chokes suppress common mode noise: the two windings present high impedance to common mode current while keeping the effect on differential mode current low. Power line common mode chokes sit in the supply path, so focus on rated current, DC resistance and temperature rise. Signal line common mode chokes sit on differential pairs, so focus on common mode impedance and signal integrity impact. The two types are not interchangeable.
Power inductors store energy and filter current in DC-DC supplies. Molded power inductors have low magnetic leakage and good saturation behaviour for high-current-density buck circuits. High current power bead inductors are low-nanohenry parts for multiphase buck power stages. Start with inductance and operating current, then check saturation current, DC resistance and size.
Common mode impedance and saturation current are specified at the test frequency and temperature given in each datasheet. Compare part numbers under the same conditions.
