Capacitors are passive electronic components that store electrical energy in an electric field. They consist of two conductive plates separated by a dielectric material. Capacitors perform critical functions such as:
Energy storage
Power filtering
Voltage stabilization
Signal coupling and decoupling
Noise suppression
Timing and frequency control
Capacitors are essential across all modern electronic systems from smartphones to EV powertrains and high-voltage industrial equipment.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Ceramic Capacitors | Compact size, high-frequency performance, low ESR | Mobile devices, RF circuits, decoupling |
| Electrolytic Capacitors | High capacitance density, polarized operation | Power supplies, audio amplifiers, motor drives |
| Film Capacitors | Self-healing properties, low dielectric loss | AC systems, electric vehicles, lighting ballasts |
| Supercapacitors | Ultra-high energy density, rapid charge/discharge | Renewable energy storage, hybrid vehicles, backup power |
A standard capacitor includes:
Advanced designs incorporate multilayer configurations (MLCCs) or wound electrode assemblies for enhanced performance.
| Parameter | Significance |
|---|---|
| Capacitance ( F/nF/pF) | Defines energy storage capacity |
| Rated Voltage (V) | Determines operational safety limits |
| Tolerance (%) | Indicates precision of capacitance value |
| ESR (Equivalent Series Resistance) | Affects high-frequency performance and heat generation |
| Temperature Coefficient (ppm/ C) | Measures stability over temperature variations |
Major application domains include:
| Manufacturer | Representative Products |
|---|---|
| TDK Corporation | CKG Series MLCCs, CGA Series Automotive Capacitors |
| Murata Manufacturing | GRM Series Ceramic Capacitors, DMT Series DC-Link Capacitors |
