Capacitors

Explore capacitors for filtering, coupling, decoupling, timing, energy storage and power supply applications. Find electrolytic, ceramic, film, tantalum and other capacitor types in a wide range of capacitance values, voltage ratings, tolerances and package formats for electronic circuits, repair and prototyping.

How to choose the right capacitor

Choose a capacitor according to its capacitance, maximum operating voltage, tolerance, dielectric type, temperature characteristics and package. Electrolytic capacitors are commonly used for power supply filtering and energy storage, ceramic capacitors for decoupling and high-frequency applications, and film capacitors for signal, timing and other circuits that require good electrical stability.

Before ordering, check whether the capacitor is polarized, its lead spacing or SMD package, physical dimensions and operating temperature. For replacement applications, use a capacitance value that matches the original component and select a voltage rating equal to or higher than the circuit requirement while respecting the available mounting space.
