Power inductors: SMT design with increased current capability
TDK Corporation presents a new series of EPCOS SMT power inductors whose current capability is 10 percent higher than existing types. The components of the improved and highly reliable B82476B1*M100 series of SMT power inductors are designed for rated currents between 0.33 A and 7.5 A. The spectrum of inductance values ranges from 1.0 µH to 1000 µH, and the typical DC resistance is between 6.0 mΩ and 1.95 Ω.
The power inductors, which are qualified to AEC-Q200, are suitable for operating temperatures from -55 °C to +150 °C and thus fulfill the rigorous requirements for automotive electronics applications. Designed with a base plate, the unshielded components offer high mechanical stability. The new inductors have a footprint of 12.95 mm x 9.40 mm and an insertion height of 5.08 mm. The components are RoHS-compatible and suitable for lead-free soldering to JEDEC J-STD-020D. The main applications for the high power inductors are DC-DC converters in automotive electronics and switch-mode power supplies (SMPS) for demanding industrial electronics applications.
