SDFL3216 | Multilayer Chip Ferrite Inductors
Product Introduction
Sunlord SDFL3216 is a multilayer chip ferrite inductor in 3216 (3.2×1.6×0.85/1.1mm). The monolithic (sintered one-piece) construction is compact, magnetically self-shielded with no cross-coupling, and compatible with reflow/wave soldering; 0.047μH~47μH (3216series) from -40°C~+85°C suits signal-line filtering, EMI suppression and RF matching in communications, AV, computer and consumer designs.
Core Advantages
- Multilayer Chip Ferrite Inductors: 3216 (3.2×1.6×0.85/1.1 mm), 0.047–47 μH — monolithic sintered ferrite body — compact, self-shielded and SMT friendly.
- Low DCR, high current: DCR 0.15Ω~3.4Ω; saturation current up to 300mA — high DC-bias performance in a 3216 body.
- Compliance: Hazardous Substance Free (HSF), RoHS compliant.
- Supply: YQM ELECTRONICS holds Sunlord stock with fast samples, datasheets and FAE support for volume programs.

FAQ
Q: How is SDFL different from a wire-wound RF inductor?
A: SDFL is a monolithic sintered ferrite structure: lower cost, self-shielded and suited to signal filtering and EMI suppression, while wire-wound ceramic types offer higher Q and SRF for precision RF matching.
Q: At what frequency is SDFL3216 specified?
A: The inductance test frequency varies with the value — 50/25/10/4/2/1/0.4 MHz across the range, following the datasheet part-number rule.
