Aluminum - Polymer Capacitors

2.5SXE220M capacitors are aluminum-polymer capacitors based on organic sputtered metallized and solid-state electrolytes that provide improved thermal and electrical performance compared with traditional capacitors. This type of capacitor has the advantage that it is self-healing and that it does not suffer from the “solder joint” problem often found with standard electrolytic capacitors. In addition, these capacitors have excellent ripple current handling capabilities, excellent temperature coefficient characteristics, and low ESR. This makes them ideal for use in a variety of electronics applications.

The 2.5SXE220M is a low profile, surface-mount device, with an overall profile of just 2.5mm, allowing it to fit comfortably in the tightest spaces. It comprises of two semiconductors that function as the electrodes and the electrolytic material and is typically constructed using a metalized substrate, etched with a sputtered layer of aluminum or other metals, making it highly durable and resistant to shock and vibration. This capacitor has a capacitance range of 0.47 – 2200 μF, and an operating temperature range of -55 to +105°C.

These capacitors are widely used in quality audio applications, including power supplies, amplifiers, audio systems, displays and other equipment that requires low electrical resistance and high temperature stability. They are also effectively used for power decoupling in digital systems and voltage filtering in automotive, telecom and industrial applications.

The 2.5SXE220M operates on the principle of displacement. The dielectric material within the capacitor is allowed to change its shape in response to a changing electrical field, creating a displacement current within the capacitor and thereby charging the capacitor. This charge can later be dissipated off as electrical energy when required. The capacitance of the capacitor is determined by the amount of dielectric material it has, combined with the surface area of the two electrodes.

In conclusion, the 2.5SXE220M is an ideal choice for a wide range of electronics applications due to its excellent electrical properties, good thermal performance, and low profile design. This makes these capacitors highly versatile and suitable for use in both rugged and demanding environments.
