LGA0410 Axial Lead Color Ring Inductor RoHS Fixed Choke Coil For Power Supply
The Chipsen LGA0410 color ring inductor is an axial leaded fixed inductor with a Φ4.0 × 10.0 mm epoxy-coated body, tinned copper leads and 4-band color code marking. It combines a ferrite or iron-powder core with 100% full-copper enameled wire to deliver stable inductance, low DC resistance and reliable self-resonant behaviour in DC-DC filtering, EMI suppression, LED drivers, power supplies, home appliances and automotive electronics. Inductance is available from 1µH to 10mH with ±5% / ±10% / ±20% tolerance, and every value is produced to order under an IATF16949 quality system.
- Wide inductance coverage: 1µH–10mH in one mechanical footprint, simplifying BOM standardisation across multiple boards.
- Clear 4-band color code: value and tolerance readable from any angle – fewer assembly errors than printed axial parts.
- 100% full-copper enameled wire: lower DCR, lower temperature rise and better current handling than copper-clad-aluminium alternatives.
- Epoxy resin coating, UL94 V-0 flame rating: moisture-proof, shock-resistant and suitable for wave-soldering processes.
- Solderability: tinned leads, RoHS & REACH compliant, lead-free reflow / wave soldering friendly.
- Full customisation: inductance, tolerance, DCR, rated current, lead length and packing form can all be tailored (OEM / ODM welcome).

It refers to the body size of the axial inductor: approximately Φ4.0 mm in diameter and 10.0 mm in length.
The first two bands are significant digits, the third is the multiplier and the fourth is the tolerance, with the value expressed in µH – the same logic as a resistor color code.
Yes. Inductance, tolerance, DCR, rated current and lead length are all customisable; simply provide your circuit requirement or a competitor part number.
Production is MTO with 3–4 weeks lead time; payment by T/T. Contact us with your annual usage for tiered pricing.
Yes – free or chargeable samples plus LCR, DCR and temperature-rise test reports can be supplied for qualification.
Send your inductance value, tolerance, rated current and annual quantity, and our engineer will reply with a drawing, datasheet and quotation within one working day.
