SMD Ultra-High-Current Molded Inductor — INRT Series
T-Core Flat Coil High Current Hot-Press Molded Inductor. Carbonyl-iron powder die-casting combined with 220℃ flat-wire hot-press molding achieves lower DCR and higher saturation current within the same footprint.

Operating range
Built for High-Current Power Stages
The INRT series uses a carbonyl-iron powder core with flat-wire construction, hot-press molded at 220℃. The result is a fully shielded, soft-saturation inductor that holds inductance under load while minimising DC resistance — ideal for the output stage of high-current DC-DC converters.
Product Features
Low Loss, Low DCR
Carbonyl-iron powder core with flat wire delivers significantly lower DCR than conventional wound structures at the same size.
High Saturation Current
Soft-saturation characteristics with Isat up to 95 A — ideal for high-current DC-DC output stages.
Low Noise, Magnetically Shielded
Closed magnetic path with full shielding: minimal flux leakage and low audible noise.
Low Parasitic Capacitance
Optimised flat-wire interlayer structure for low parasitic capacitance and good high-frequency performance.
Halogen-Free, RoHS Compliant
Halogen-free throughout the process, meeting RoHS environmental requirements.
Automotive-Grade Reliability
Reliability testing per AEC-Q200, operating temperature −55℃ to +155℃.
