Additional Details

The 1008CS-122XJEC has an inductance value of 1.2 μH (microhenries) with a tolerance that's typically around ±5% or ±10%, indicated by the part number suffix. It features a high Q-factor, which indicates low energy loss and high efficiency in resonant circuits. The self-resonant frequency (SRF) is the frequency at which the inductor's behavior changes from inductive to capacitive. This inductor's SRF is typically in the MHz range, making it suitable for high-frequency applications. The DC resistance (DCR) is low, minimizing power loss in the inductor. It is designed for reflow soldering processes commonly used in PCB assembly. The operating temperature range typically falls between -40°C to +125°C. Coilcraft inductors are known for their rugged construction and reliable performance.
