Product Description
1uH-10mH T30 Toroidal Power Inductor High Current for Solar Inverter UPS EV Charger
Product Overview
T30 Toroidal Power Inductor — High Current Iron Powder Core Choke Coil, OEM & ODM Customization
The Chipsen T30 toroidal power inductor is a through-hole magnetic ring inductor built on a 30 mm outer-diameter toroidal core and wound with enameled copper wire. Its closed magnetic path delivers low EMI radiation, low core loss and stable inductance under DC bias, making it a reliable filtering and energy-storage component for switching power supplies, solar inverters, UPS systems and EV on-board chargers.
Every T30 inductor is made to order: inductance value, current rating, core material, wire gauge, pin length and terminal style are all engineered to your circuit and PCB layout. Send us your schematic, target inductance or a sample — we return a drawing within 3 working days.
Key Advantages
- Low MOQ — 100 pcs. Friendly to prototype runs, R&D projects and small-batch production.
- Fast response. Quotation within 3 days, sample production within 7 days after drawing confirmation.
- 5-year warranty, extended to 20 years for special industries (rail, medical, energy storage and other long-life applications).
- Full OEM & ODM support. Custom inductance, current, core material, winding structure, marking and packaging.
- High efficiency & low noise. Toroidal closed-loop core minimises leakage flux, audible noise and temperature rise.
- Stable performance. Wide operating temperature range and consistent inductance tolerance batch after batch.

Frequently Asked Questions
Q1: What is a T30 toroidal power inductor used for?
It is a magnetic-ring choke coil used for energy storage, ripple filtering and EMI suppression in switching power supplies, inverters, UPS units and EV chargers.
Q2: Can I get a custom inductance and current rating?
Yes. The T30 is fully customizable — inductance, rated current, core material, wire gauge and pin length are all designed around your circuit.
Q3: What is the minimum order quantity?
100 pieces, which makes the T30 suitable for prototypes and small-batch projects.
Q4: How long does sampling take?
A drawing is issued within 3 days and samples are produced within 7 days after your confirmation.
Q5: Which core material should I choose?
Iron powder and sendust suit high DC-bias power chokes; ferrite and nanocrystalline suit higher switching frequencies and common-mode filtering. Send us your working frequency and we will recommend the best option.
Q6: Do you provide test reports and certificates?
Yes — inductance/DCR test data, hi-pot records and RoHS/REACH declarations are available on request.
