SMD open field high current inductors with bakelite base (SDB SERIES)
SDB Series: High-Q Unshielded Inductors for DC-DC & RF (Bakelite Base)
The SDB Series is a family of unshielded wire-wound SMD power inductors featuring a reinforced bakelite base for superior mechanical stability and protection during SMT assembly. Using a fine-tuned Ni-Zn ferrite core formulation, SDB inductors provide significantly higher Q performance and superior SRF compared to standard unshielded parts, enabling dual use in both high-efficiency DC-DC power regulation and signal-transfer applications such as RFID.
By combining small footprint options (down to 2.0 mm height) with enhanced Q characteristics, the SDB Series targets compact, cost-efficient designs that require both reliable current capability and low-loss high-frequency behavior. This makes it a versatile drop-in choice for portable communications, computing devices, and RF-related modules.
When to Choose SDB?
Select SDB when a design requires: lightweight DC-DC inductors with higher SRF, strong Q performance for signal transmission, and added reliability from a reinforced core baseāwithout paying the cost overhead of magnetic shielding.
Key Highlights
High-Q Ni-Zn ferrite formulation optimized for low loss and superior SRF
