The 0.1µF (100nF / 104) Multilayer Ceramic Capacitor (MLCC) is one of the most essential and widely used components in electronics. Known as the gold standard for decoupling and bypass applications, this capacitor provides low impedance at high frequencies to filter power supply noise and ensure stable operation of ICs and microcontrollers [citation:4][citation:8].
The 0.1µF MLCC is available in many package sizes and voltage ratings to suit different applications. The following table shows some common variants:
| Parameter | Example Option 1 | Example Option 2 | Example Option 3 |
|---|---|---|---|
| Capacitance | 0.1µF (±10%) | 0.1µF (±10%) | 0.1µF (±10%) |
| Voltage Rating | 50V DC | 25V DC | 16V DC |
| Dielectric | X7R | X7R | X5R |
| Temperature Range | -55°C to +125°C | -55°C to +125°C | -55°C to +85°C |
| Package (SMD) | 0603 (1608 metric) | 0805 (2012 metric) | 0201 (0603 metric) [citation:1][citation:9] |
| Application | General-purpose decoupling | General-purpose decoupling | Ultra-compact designs |

UltraLow ESR/ESL Provides excellent high-frequency noise suppression for power rails
Wide Voltage Range Available from 6.3V to 630V to suit lowpower to high-voltage applications [citation:1][citation:7][citation:12]
Multiple Dielectric Options Choose X7R for wide temperature stability, X5R for generalpurpose, or C0G/NP0 for highest stability [citation:2][citation:11]
Small Form Factors SMD packages down to 0201 enable highdensity PCB designs [citation:1]

Varies by seller - typically available in:
Avoid using highK dielectrics (X5R, X7R) in precision timing circuits - capacitance varies with DC bias and temperature
Avoid exceeding voltage rating for 50V rated parts, recommended operating voltage is typically ≤40V for reliable operation
Avoid placing decoupling capacitors too far from ICs increased trace inductance reduces effectiveness at high frequencies
