The "47" or "470" marking indicates 47pF - first two digits are significant, third is multiplier (47 x 10⁰ = 47pF)
For crystal oscillator circuits, 47pF is commonly used for crystal loading - check your crystal datasheet for exact value
For RF decoupling, place capacitor as close as possible to the IC power pin
For highreliability applications, select NP0/C0G or AECQ200 rated variants
For precision timing circuits, use NP0/C0G dielectric for ±30ppm/°C temperature stability
For automotive applications, select AEC-Q200 qualified variants with higher temperature ratings
Avoid using highK dielectrics (X7R, Y5V) 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 high-frequency effectiveness
