TDK provides extremely compact and reliable CLT power inductors for ADAS and AD power management

     TDK Corporation's CLT32 series power inductors offer extremely compact dimensions and excellent electrical values. The nine models range in inductance from 17 nH to 440 nH and are designed for saturation currents of 13.5 A to 60 A. The compact size of 3.2 mm x 2.5 mm and the insertion height of 2.5 mm make these SMT power inductors extremely compact. They are designed for temperatures ranging from - 40 ° C to+165 ° C, including self heating.

     These AEC-Q200 certified components have a solid copper coil design and are clad with ferromagnetic plastic composites. The end of the coil is used as a terminal, which significantly improves reliability, especially in automotive applications. With solid copper coils, these products can achieve very low RDC values and minimize losses. When the inductance value is 17 nH, the ohmic resistance is only 0.39 m Ω.

     The compact and highly robust CLT32 inductor is ideal for safety critical automotive applications in ADAS/AD. High performance processors used in these areas require current in the two digit ampere range. The power management IC (PMIC) is used to provide these high current power supplies and uses power inductors to stabilize key components on the output. The CLT32 model is designed for switching frequencies up to 10 MHz and meets future requirements for DC/DC converters with high clock rates
