Table 10: Capacitor type overview
Capacitor type Description
C0G/NP0
(Type 1 ceramic)
Use in signal path, filtering, low distortion, audio, and precision
Limited capacitance range: 0.1 pF to 0.47 µF
Lowest temperature coefficient: ±30 ppm/Ԩ
Low-voltage coefficient
Minimal piezoelectric effect
Good tolerance: ±1% to ±10%
Temperature range: –55Ԩ to 125Ԩ (150Ԩ and higher)
Voltage range may be limited for larger capacitance values
X7R
(Type 2 ceramic)
Use for decoupling and other applications where accuracy and
low distortion are not required
X7R is an example of a type 2 ceramic capacitor
See EIA capacitor tolerance table for details on other types
Capacitance range: 10 pF to 47 µF
Temperature coefficient: ±833 ppm/
Ԩ
(±15% across temp range)
Substantial voltage coefficient
Tolerance: ±5% to –20%/+80%
Temperature range: –55Ԩ to 125Ԩ
Voltage range may be limited for larger capacitance values
Y5V
(Type 2 ceramic)
Use for decoupling and other applications where accuracy and
low distortion are not required
Y5V is an example of a type 2 ceramic capacitor
See EIA capacitor tolerance table for details on other types
Temperature coefficient: –20%/+80% across temp range
Temperature range: –30Ԩ to 85Ԩ
Other characteristics are similar to X7R and other type 2 ceramic
Aluminum oxide
electrolytic
Use for bulk decoupling and other applications where large
capacitance is required
Note that electrolytic capacitors are polarized and will be
damaged, if a reverse polarity connection is made
Capacitance range: 1 µF to 68,000 µF
Temperature coefficient: ±30 ppm/Ԩ
Substantial voltage coefficient
Tolerance: ±20%
Temperature range: –55Ԩ to 125Ԩ (150Ԩ and higher)
Higher ESR than other types
Tantalum
electrolytic
Capacitance range: 1 µF to 150 µF
Similar to aluminum oxide but smaller size
Polypropylene
film
Capacitance range: 100 pF to 10 µF
Very low voltage coefficient (low distortion)
Higher cost than other types
Larger size per capacitance than other types
Temperature coefficient: 2% across temp range
Temperature range: –55Ԩ to 100Ԩ
