Compact TDK Automotive Power Inductor for Space-Critical Designs
High-Temperature Reliability for Automotive Power Circuits
Engineered to operate reliably under extreme conditions, the inductor guarantees stable performance up to 155°C. This thermal capability ensures consistent functionality in high-load and high-temperature automotive environments, including powertrain electronics, body control modules, and advanced ECU architectures where thermal margins are increasingly tight.
Flat-Wire Design Improves Efficiency and Reduces Losses
TDK achieved lower resistance and improved efficiency by replacing conventional round wire with a flat-wire winding structure. This design choice significantly reduces heat generation and electrical losses, supporting higher efficiency across power circuits. As a result, ECU systems can achieve better energy utilization without compromising reliability.
Higher Rated Current Expands ECU Application Range
Compared with existing solutions, the new inductor delivers approximately 1.28 times higher rated current. This performance increase allows the TDK automotive power inductor to support a broader range of ECU functions, including power management, voltage regulation, and electronic control systems across multiple vehicle domains.
Automotive-Grade Compliance and Scalable Production
The BCL3520FT Series complies with AEC-Q200 automotive-grade standards, ensuring durability under vibration, temperature cycling, and high electrical load. TDK has established a production system in Japan with a capacity of around 100,000 units per month, reinforcing supply stability for automotive manufacturers and Tier-1 suppliers.
