Ceramic Capacitors are low-cost and high-speed switching capacitors. They are normally used for noise filtering, tuning, coupling, and other applications. They can also be found it RC, LC, and RLC filters. Ceramic capacitors can switch faster than electrolytic capacitors, but they are not available in high capacitance values. Features of this 33pF ceramic capacitor are:
 
Capacitance: 33pF
Voltage: 50V (assumption)
Type: Ceramic Radial through hole
Package Marking: 33
 
Applications:
Filter circuits like High/Low pass filter etc.
For Filtering noise from a circuit
Smoothing ripples in converters
For decoupling and by-pass circuits
Fading LED circuits
Resonant circuits.
