Product Description
DR3W10 Radial Lead 3-Pin Drum Core Fixed Inductor for Power Supply
Chipsen DR3W10 Three-Leg Drum Core Inductor — Radial Leaded Power Choke for Switching Power Supplies
The Chipsen DR3W10 is a three-leg (3-pin) radial leaded drum core power inductor built on a ferrite DR core and fully encapsulated in a black flame-retardant epoxy body. The extra third pin provides a rugged mechanical anchor on the PCB and allows tapped / dual-winding configurations, making the part a stable choice for switching power supplies, LED drivers, chargers, EMI input filters and home appliance control boards. Every unit is wound with enameled copper wire, terminated with tin-plated oxidation-resistant pins, and produced under an ISO9001:2015 / ISO14001:2015 / IATF16949 quality system with UL/cUL, RoHS, REACH and CQC compliance.
Key Features
- Compact molded structure — epoxy-encapsulated drum core resists vibration, moisture and mechanical shock, keeping inductance stable in the field.
- Oxidation-resistant pins — tin-plated leads with excellent solderability, suitable for wave soldering and long-term storage.
- Three-leg mounting interface — the third pin locks the component to the board and supports tapped-winding designs.
- Clear product identification — laser/printed marking on the body for fast line-side verification and traceability.
- High efficiency & low noise — ferrite DR core with optimized winding lowers core loss, audible noise and EMI.
- Wide operating range — designed for -40°C to +125°C ambient conditions.
- Full customization — inductance, current rating, wire gauge (including TIW), core size and pin length made to your drawing.

Frequently Asked Questions
Q1: What is the advantage of a three-leg inductor over a standard two-pin type?
A: The third pin improves mechanical retention on the PCB and enables a tap or a second winding, so one component can handle both energy storage and an auxiliary/feedback function.
Q2: Can you produce the DR3W10 to my own inductance and current rating?
A: Yes. Inductance, rated current, DCR, wire type and pin length are all customizable — just send your specification or drawing.
Q3: What is the minimum order quantity and sample policy?
A: MOQ is 100 pcs. Samples are produced within 7 days after the specification is confirmed.
Q4: Are the parts RoHS and REACH compliant?
A: Yes. Materials are RoHS and REACH compliant, and UL/cUL recognized insulation systems are available on request.
Q5: How are the inductors packed for export?
A: Anti-static inner bags plus foam-protected export cartons, with moisture-proof packing available for sea freight.
