It is one of the most common high-frequency decoupling capacitors.<\/p>\n\n\n\n<p><strong>Is 102 capacitor suitable for power filtering?<\/strong> <br>Yes, for high-frequency noise. It is typically paired with a larger capacitor (e.g., 100nF or 10\u03bcF) for full-spectrum filtering.<\/p>\n\n\n\n<p><strong>What is the difference between 102 and 104 capacitor?<\/strong> <br>102 = 1 nF; 104 = 100 nF. 104 handles lower frequencies, while 102 targets very high frequencies.<\/p>\n\n\n\n<p><strong>Can 102 capacitor fail in SMT assembly?<\/strong> <br>Yes. Common failures include cracking due to mechanical stress or tombstoning during reflow.<\/p>\n\n\n\n<p><strong>Where is 102 capacitor used on PCB?<\/strong> <br>Primarily on MCU power pins, RF modules, and oscillator circuits for noise suppression.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What value is a 102 capacitor?
