SMD Open Field High Current Inductors (SDO / SDH SERIES)
Mn-Zn Core Open-Magnetic High-Current SMD Inductors
The SDO/SDH platform offers two distinct termination structures: Cu/Sn clips (SDO) for best cost and stability, or wire-leads (SDH) for layout flexibility. Custom inductance and pad configurations are available to match specific electrical targets and mechanical layout constraints.
Termination Architecture (SDO vs. SDH)
SDO Series: Uses Cu/Sn copper clips for PCB pad termination ā best cost/performance and mechanical stability. SDH Series: Uses wire-lead terminations for alternative layouts or drop-in compatibility needs.
Performance Benefits of Mn-Zn Open-Core
Performance Benefits of Mn-Zn Open-Core
Higher Isat / Irms performance via Mn-Zn ferrite core; Open magnetic circuit enables compact volume & lower material cost; Best used where EMI containment is not critical; Customizable inductance and footprint across multiple pad options
Characteristic
High current capability (Isat/Irms) via Mn-Zn high-Ī¼ ferrite core
Lower DCR for improved efficiency in current-intensive rails
Efficient energy storage for heavy load switching and fast transient response
Open magnetic design lowers material cost and significantly improves heat dissipation
Structurally compact, low-noise footprint without full shielding cost
Features
- Higher Isat & Irms performance than comparable Ni-Zn open-magnetic inductors
- Available in clip-type (SDO) or wire-lead (SDH) pad options for design flexibility
- Compact and low-noise footprint without the cost overhead of full shielding
- Customizable inductance and footprint for drop-in or specialized layouts
- RoHS, REACH, and Halogen-Free compliant
Applications
- High-current DC-DC converters / Power rails for tablets, notebooks, PCs, handheld devices / Step-up & step-down converters / Power modules requiring strong current capability without full EMI containment
