Unshielded Inductor SDR-T

Product Overview

The Unshielded Inductor SDR-T series delivers robust performance in high-frequency power systems. Featuring an open magnetic structure, these inductors achieve ultra-low DCR (down to 0.0098Ω) and current handling up to 7.2A. Ideal as a Power Inductor for space-constrained designs, their unshielded architecture reduces core losses while supporting RF Inductor applications at test frequencies up to 7.96MHz.

Key Features

• Unshielded Design: Eliminates core saturation for stable inductance (1μH–1200μH ±30%)

• High Current Rating: 0.15A to 7.2A (IDC @10% drop)

• Low DCR: 0.0098Ω–6.2Ω (optimized for Power Converter efficiency)

• High-Frequency Operation: Tested at 0.252–7.96MHz for RF Inductor compatibility

• Thermal Resilience: -40°C to +105°C operating range

• EMC Filter Ready: Reduces electromagnetic noise in power buses
