Custom KS225 Toroidal PFC Inductor for EV Charger UPS Pure Copper Boost Choke
KS225 Toroidal PFC Inductor – Common Mode & Boost Choke for PV Inverters, EV Chargers and UPS
The Chipsen KS225 PFC inductor is a toroidal power choke designed for power factor correction (PFC) and boost stages in high-efficiency switching power systems. It uses a closed toroidal magnetic core with an evenly distributed single-layer winding of pure copper wire, delivering low DCR, low leakage flux and a controlled temperature rise under continuous load. The winding is fixed on an epoxy-potted base with rigid through-hole pins, so the component stays mechanically stable on the PCB under vibration and shock — a key requirement for solar inverters, EV chargers and industrial drives.
KS225 is built to order (MTO): inductance, current rating, wire gauge, core material and pin layout are customized to your circuit and can be delivered against your drawing or a reverse-engineered sample.
Key Features
Toroidal closed magnetic core – minimizes flux leakage and external EMI interference, helping the end product pass EMC testing more easily.
Evenly distributed single-layer winding – reduces DCR, AC copper loss and temperature rise; improves overall conversion efficiency.
Epoxy-potted base – secures the windings against vibration, shock and transport stress; no loose turns, no audible noise.
PCB base with rigid pins – stable vertical through-hole mounting, consistent height and footprint for automatic insertion and wave soldering.
Pure copper winding wire – no copper-clad aluminium; stable resistance, better thermal behaviour and reliable long-term operation.
Full custom engineering – inductance, saturation current, core material (sendust / high-flux / ferrite / nanocrystalline) and terminal style tailored to your topology.
Quality system in place – manufactured under ISO9001:2015, ISO14001:2015 and IATF16949; materials to UL/cUL, RoHS, REACH and CQC requirements.

FAQ
Q1: What is a PFC inductor used for?
A PFC inductor stores and releases energy in the boost stage of a power factor correction circuit, shaping the input current to follow the AC voltage waveform. This raises the power factor, lowers harmonic distortion (THD) and helps the equipment meet grid and EMC requirements.
Q2: Can KS225 be customized to my inductance and current?
Yes. Inductance, rated/saturation current, core material, wire gauge, number of turns, pin pitch and base type are all customizable. Send your specification, schematic or a physical sample and we will issue a drawing for confirmation.
Q3: Why a toroidal core instead of an EE/EI core?
A closed toroidal core has no air gap in the main flux path, so leakage flux and radiated EMI are much lower than a gapped EE/EI structure. This usually means less shielding effort and easier EMC compliance in inverter and charger designs.
Q4: Is the winding pure copper?
Yes, pure copper wire is used as standard — no copper-clad aluminium. Litz wire is available for high-frequency designs where AC copper loss must be minimized.
Q5: What is the sample and mass production lead time?
Drawings are provided within 3 days and samples within about 7 days after specification is confirmed. Mass production lead time depends on quantity and material — please contact us with your target volume and schedule.
Q6: What certifications do you hold?
Our factory operates under ISO9001:2015, ISO14001:2015 and IATF16949. Materials used are UL/cUL recognized and comply with RoHS, REACH and CQC requirements. Certificates can be provided upon request.
Need a PFC inductor for your design? Send us your inductance, current, frequency and space limitation — our engineers will recommend the right core and winding, and return a drawing within 3 working days.
