Additional Details

The 1008CS-472XKLC has an inductance value of 4.7 µH (microhenries). The tolerance is typically around ±10%. The Self-Resonant Frequency (SRF) is a crucial parameter for RF inductors, and the 1008CS-472XKLC is designed to have a high SRF, allowing it to operate effectively at high frequencies. The DC resistance (DCR) is kept low to minimize power loss. It's constructed using ceramic core material to ensure its high Q factor and stable performance. This inductor is typically used in impedance matching networks, filters, and RF chokes.
