Development of High Reliability SMT Type Inductors for Automotive Electronics
TDK has released a new SMT type inductors offering 30% more saturation current than standard series type. The saturation current for the new inductor is between 1.05 A to 38.0 A at inductance values from 0.82 to 1000 uH. Also, the DC resistance is between 5.0 milliohm and 1.35 ohm. The new inductors come in a footprint of 12.5 x 12.5 mm2 and a maximum insertion height of 8.5 mm. They feature magnetic shielding, making possible to place the inductors in direct proximity to other components on circuit board. With operating temperature of between -55 to +150 degrees Celsius, the new B82477R series of inductors can satisfy the rigorous requirements of automotive electronics and are qualified to AEC-Q200.
Among some of the application for the new inductor series are power supply units in automotive electronics such as for LED lighting systems as well as clocked power supplies which require high reliability and high temperature range.
