Ultra compact and reliable CLT power inductor sample kit

     TDK has introduced an ultra-compact and reliable CLT32 power inductor count kit for ADAS/AD power management applications. The new sample kit includes nine inductors with part number B82403X1 with different inductance values, covering an inductance range of 17 nH to 440 nH and saturation current range of 13.5 A to 60 A.

     These components are extremely compact in size, with a board area of 3.2 x 2.5 mm and a height of 2.5 mm, making them the most compact SMT power inductors in their class, with operating temperatures ranging from -40°C to 165°C (including the inductor's self-temperature rise).

     They are AEC-Q200 certified and are made of solid copper coils wrapped in ferromagnetic plastic composites. The end of the coil is directly used as an inductance pad, which greatly improves the reliability of the product and is ideal for automotive applications. The solid copper coil structure also achieves an extremely low RDC value (resistance of 0.39 mΩ for inductance of 17 nH), thus minimizing losses even more.

     The compact size and reliable performance of the CLT32 Series inductors make them ideal for safety-critical ADAS/AD applications in the automotive industry. In such applications, high performance processors with current ratings up to double digits are often required, and a PMIC (Power management IC) is used as a power supply to provide high current, while a power inductor is used as a key component to stabilize the power output. The CLT32 family of components is specially designed for high frequency switching frequencies, with application frequencies up to 10MHz, meeting the requirements of future high frequency DC/DC converters in advance.
