68nF Multilayer Ceramic Capacitor (MLCC)
= Versatile 68nF Capacitor for Filtering and Decoupling Applications =
The 68nF (0.068µF) Multilayer Ceramic Capacitor is a midrange capacitance value ideal for decoupling, filtering, and smoothing applications. Available in both throughhole and surfacemount packages, this capacitor offers stable performance across a wide temperature range with low ESR for highfrequency circuits.
Capacitance value: 68nF = 0.068µF = 68,000pF (marked as "683" on the component)
Commonly used for power supply decoupling, noise suppression, and filtering circuits
Do not exceed the rated voltage voltage derating is recommended for reliable longterm operation
MLCCs can exhibit capacitance reduction under DC bias - refer to manufacturer datasheets for derating curves

= Package Includes =
Varies by seller - typically available in:
- Tape and reel (SMD) - quantities from 100 to 10,000+ pieces
- Bulk packs (throughhole) quantities from 10 to 1,000+ pieces
- Cut tape / loose pieces for prototyping
For general-purpose decoupling, a 68nF X7R 50V capacitor in 0603 or 0805 package is a popular choice
The 683 marking indicates 68nF - first two digits are significant, third is multiplier (68 x 10³ = 68,000pF)
For high-reliability applications, select NP0/C0G dielectric for ±30ppm/°C temperature stability and ±5% tolerance
This capacitor is ideal for fine-tuning filter circuits where 47nF is too low and 100nF is too high
For hightemperature automotive applications, select AECQ200 rated variants
Avoid using highK dielectrics (X5R, X7R) in precision timing circuits - capacitance varies with DC bias and temperature
Avoid exceeding rated voltage for 50V rated parts, recommended operating voltage is typically ≤40V
Avoid placing decoupling capacitors too far from ICs increased trace inductance reduces effectiveness at high frequencies
