Place the capacitor as close as physically possible to the power pins to minimise lead inductance and maximise high‑frequency noise suppression. For RC filtering, solder the capacitor in series with a resistor – this creates a simple low‑pass filter for signal conditioning.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdiv class=\"faq\"\u003e\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003ch3\u003eWhat is the difference between 100nF, 0.1µF, and the 104 marking on the capacitor?\u003c\/h3\u003e\n    \u003cp\u003e100nF equals 0.1µF; the marking “104” means 10 followed by four zeros in picofarads (100,000pF = 100nF).
