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.
Note: inductance, rated current, DCR and dimensions are built to order. Send us your electrical parameters or drawing and we will confirm the exact datasheet.
Typical Applications
Switching power supplies, adapters and battery chargers
LED lighting drivers and ballasts
EMI / differential-mode input filters and DC-DC converters
Home appliance and small motor control boards
Industrial instrumentation, security and communication equipment

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.
