KingCore FAQs

Before you call sales.

What is KingCore Electronics?

King Core Electronics Inc. (KingCore) is a TWSE-listed (stock code 6155) Taiwanese manufacturer of magnetic components, founded in 1986 in Taoyuan, Taiwan. The company specialises in power inductors, common-mode chokes (CMCs), ferrite cores, SMD chip beads and EMC/EMI filtering components for power supply, automotive, industrial and telecom applications worldwide.

Is Belden an authorized KingCore distributor?

Yes. Belden Electronic Components is an authorized franchise distributor of King Core Electronics Inc., supplying power inductors, common-mode chokes, ferrite cores and SMD chip beads direct from the manufacturer with full traceability and date-code documentation.

What is a common-mode choke?

A common-mode choke (CMC) is a two-winding inductor wound on a shared ferrite core. It presents high impedance to common-mode noise — interference that appears identically on both signal lines — while passing differential-mode signals with low insertion loss. CMCs are widely used for EMI suppression on power supply inputs, USB and data lines, motor drive outputs and EV on-board charger circuits.

Which KingCore products are suitable for automotive applications?

KingCore offers AEC-Q200-qualified power inductors and common-mode chokes produced under IATF 16949 quality management. These automotive series are rated for extended temperature ranges, vibration and the strict reliability levels required by automotive OEMs for ECUs, ADAS, EV/HEV on-board systems and in-vehicle networking. Contact Belden for the current qualified part list.
