Additional Details

The PM1008-4R7K-RC inductor conforms to the 1008 EIA standard size. This means it has a length of 0.1 inches (2.54 mm) and a width of 0.08 inches (2.03 mm). The wire-wound construction provides a high Q value, which is a measure of the inductor's efficiency. The high self-resonant frequency (SRF) indicates the frequency at which the inductor's performance starts to degrade. This inductor is suitable for reflow soldering processes. The 'RC' likely refers to the packaging type (e.g., tape and reel). Its small size makes it ideal for use in portable devices and other space-constrained applications. The Bourns PM1008 series is known for its reliable performance and consistent quality. Typically these are used to filter unwanted frequencies, and in LC resonant circuits. These components are generally RoHS compliant indicating that they are lead-free components suitable for modern environmentally conscious designs.
