High-frequency thin film capacitors, with pure copper leads, are suitable for high-frequency oscillating circuits such as wireless charging, humidifiers, etc., featuring small size and low high-frequency loss. They can also be used to replace surface mount capacitors. Thin film capacitors have more...NPOSurface Mount CapacitorsLowLoss and better high-frequency electrical stability, the drawback being non-automatic surface mount installation. Low price, becomes a sky-high cost.NPOAlternative to surface mount capacitors.
