Capacitor Types and Characteristics

Classification by Dielectric

Ceramic Capacitor

Capacity: 1pF - 1μF

Features: Small size, good high-frequency characteristics

Application: High-frequency circuits, bypass

Electrolytic Capacitor

Capacity: 0.1μF - 10000μF

Features: Large capacity, polarized

Application: Power filtering, coupling

Film Capacitor

Capacity: 0.001μF - 10μF

Features: Low loss, good stability

Application: Audio, precision circuits

Tantalum Capacitor

Capacity: 0.1μF - 100μF

Features: Small size, good performance

Application: Precision circuits, military

Key Parameters

Parameter	Description
Capacity	Ability to store charge
Voltage rating	Maximum operating voltage
Loss	Degree of energy loss
Leakage current	Insulation performance
Temperature coefficient	Capacity change with temperature

Selection Principles

Capacity meets requirements

Voltage rating with margin (1.5-2 times)

Consider frequency characteristics

Pay attention to polarity (electrolytic capacitors)
