Product Description
Wirewound 335 SMD Power Inductor for DC-DC Converters LED Drivers
The SMD335 is a surface-mount wirewound power inductor built on a drum-type magnetic core with an enameled copper winding. Its low-profile round body and flat top face (marked 335) are designed for automatic pick-and-place assembly, while the open-winding structure keeps DC resistance low for energy-efficient power conversion. It is a cost-effective choice for DC-DC converters, LED drivers, industrial control boards and small photovoltaic control units, and it is available as a fully customized (OEM/ODM) component to match your circuit's inductance, current and footprint requirements.
Key Features
- SMT-ready package — flat top face and stable base terminals suit automatic mounting and reflow soldering, reducing assembly cost in mass production.
- Wirewound drum-core structure — enameled copper wire wound on a magnetic drum core delivers low DC resistance and good current handling in a compact footprint.
- Low loss, high efficiency — optimized winding and core pairing help limit copper and core loss, supporting cooler operation in switching power stages.
- Robust molded base — the reinforced base holds the winding securely and improves mechanical stability during transport, mounting and long-term vibration.
- Full customization — inductance, rated current, wire gauge, core material, footprint and marking can all be adjusted to your drawing or sample.
- Made-to-order supply — MTO production with stable monthly capacity; quotation and engineering feedback returned quickly after receiving your specification.

FAQ
Q1: What does the marking "335" on the top face mean?
It is the part identification code printed on the core face. Please refer to the specification sheet for the exact inductance value, or tell us the inductance you need and we will mark the part accordingly.
Q2: Can you produce a custom inductance or footprint?
Yes. Inductance, rated current, DCR, wire gauge, core material, dimensions and marking are all customizable. Send a drawing, a sample or your circuit requirement.
Q3: Do you provide samples?
Yes, samples are available for evaluation. Sample lead time and cost depend on whether the design is an existing model or a new custom item.
Q4: What is the minimum order quantity?
We support small trial orders for design-in projects and scale up to mass production. Tell us your annual usage and we will propose a tiered price.
Q5: How is the product packed and shipped?
Anti-static tape and reel or tray packing for SMT lines, then carton packing. Express, air and sea freight are all supported.
Q6: How long does it take to get a quotation?
Send the inductance, current, size and quantity you need; our sales engineer will reply with a technical proposal and price.
Need a custom SMD power inductor? Send us your inductance, rated current and footprint — we will reply with a technical proposal, sample plan and price.
