The inductance value of the 1008PS-103KLD is 10μH (based on the '103' in the part number, where '103' represents 10 x 10^3 nH or 10μH). The 'K' denotes a 10% tolerance. It is designed for surface mount technology (SMT) and comes in a 1008 package size (100 mils x 80 mils). The inductor is constructed with a wirewound coil, typically using a ceramic core for high stability. Detailed specifications, including the Q-factor, SRF, DC resistance (DCR), and current rating, are available in the Coilcraft datasheet. Careful consideration of PCB layout and soldering techniques is essential for optimal performance and reliability. These inductors are critical components in high-performance RF circuits where precise and stable inductance is required.
