High Current Shielded SMD Inductors for Automotive

Elevate Your Power Designs with Precision Engineering

At FERRTX, we engineer cutting-edge Shielding Inductor solutions that redefine reliability in high-stress environments. With 15+ years of expertise in electromagnetic components, our LOH Series delivers unmatched thermal stability, ultra-low DCR, and ferrite-shielded performance—certified RoHS/lead-free for global compliance. Whether you're optimizing automotive systems or industrial power modules, our inductors ensure 40% lower energy loss versus industry standards, backed by rigorous testing on HPA291A and HP1819A platforms.

Core Innovations: Where Performance Meets Durability

1. Uncompromising Current Handling
   Engineered for High current SMD Inductor low DCR demands, the LOH2220S-R27M achieves a breakthrough 0.007Ω DCR at 6,000mA load—ideal for EV charging systems where efficiency dictates range. Unlike conventional Power Inductor designs, our alloy-core windings reduce hotspots by 25°C (tested at +85°C ambient).
2. Automotive-Grade Resilience
   As the premier Automotive DC-DC converter inductor, the LOH series operates flawlessly from -25°C to +125°C. The ferrite shield eliminates EMI interference in ADAS sensors, while vibration-resistant terminals withstand 50G shock—validated in 5G base station deployments.
3. Drop-in Replacement Advantage
   Need to Replace TDK inductor alternative? Our LOH1210S-470K matches SLF6028 specs (470µH, SRF 3.5MHz) with 30% faster lead times. Cross-reference tables and salt-spray reports available upon request.
