Shielded Surface Mount Power Inductor (SDC SERIES)

High-Reliability Shielded SMD Inductors — Anti-Vibration, Clip-Reinforced, Gold-Plated Base

Our SDC series of magnetically shielded SMD power inductors are engineered for high-reliability applications requiring vibration resistance and stable long-term performance. The design combines a drum core with a shielded ring core, reinforced using metal clip retention and epoxy sealing to stabilize the winding under shock and vibration. The closed magnetic path reduces EMI leakage while maintaining stable inductance under DC bias.

Available in package sizes from 2D to 8D and 104R/105R formats, the SDC series delivers wide inductance coverage and strong EMI suppression. Unlike standard shielded inductors, the SDC platform features a corrosion-resistant gold-plated base along with reinforced clip fasteners, enabling superior durability in automotive, industrial, telecom, and long-duty-cycle power systems. Custom inductance values are available to match existing footprints without modifying PCB layouts.
Choose SDC when vibration resistance, mechanical reliability, or corrosion stability are critical considerations.

Mechanical Reliability Structure (Clip + Epoxy + Gold-Plated Base)

Metal retention clip reinforces the joint between the core and winding
Epoxy sealing stabilizes coils under vibration
Gold-plated base prevents oxidation during long-term operation

Core Selection for Stable DC Bias

Ni-Zn ferrite supports high EMI stability and high-frequency switching. For larger footprints (over 10 mm), Mn-Zn material reduces DCR and enhances current capability. This hybrid strategy enables optimal trade-offs between size, efficiency, and reliability.

Characteristic

Clip-reinforced mechanical structure for vibration resistance
Epoxy-sealed coil for long-term stability
Gold-plated base for corrosion prevention
Closed magnetic circuit for low EMI leakage
Stable DC bias performance for long-duty power systems

Features
  • Anti-vibration construction (clip + epoxy)
  • Corrosion-resistant gold-plated base for extended storage life
  • Excellent EMI shielding via drum + ring core closure
  • Stable DC bias characteristics under ripple stress
  • Broad inductance coverage from 0.8 µH to 10,000 µH
  • Core options (Ni-Zn / Mn-Zn depending on size)
  • Custom inductance matching existing PCB footprints
Applications
  • Automotive ECUs (interior controls, infotainment, motor control interfaces)
  • Industrial control modules with vibration exposure
  • Base station / telecom power with long-term operation
  • Power supply units requiring corrosion-resistant components
  • High-frequency DC-DC converters in portable and consumer electronics
  • Display driver & backlight power rails (TFT / LCD / LED)
