Introduction

Aluminum electrolytic capacitors are widely used in all sorts of electronic applications due to their high capacitance values and low cost advantage. This type of capacitor, typically in a cylindrical shape, consists of an anode made out of aluminum foil, a cathode made out of an oxide layer, translucent paper or metal foil, and an electrolyte. This type of capacitor helps to reduce the size and cost of modern electronics, plus it has excellent performance in today’s electronic applications.

450QXW100MEFC16X35 Application Field and Working Principle

​The 450QXW100MEFC16X35 is an aluminum electrolytic capacitor, available in a variety of sizes, with an operating voltage of 200Vdc. It can be used in power supplies, DC/DC converters, instrumentation, motors and machinery, and medical or industrial applications. The 450QXW100MEFC16X35 has an anode that consists of an anode plate and a cathode enveloped in a highly conductive electrolyte. When a voltage is applied across the capacitor, the oxide layers on the anode and the cathode folds into two parallel plates. A dielectric is formed between the two plates, creating a capacitance by storing a charge on the plates. This capacitance is determined by the dimensions of the plates, the type of electrolyte and its concentration, and the dielectric permittivity of the material between the plates.

Advantages

The 450QXW100MEFC16X35 aluminum electrolytic capacitor has several advantages over other types of capacitors. These include:

• Higher capacitance for given sizes.
• Lower equivalent series resistance (ESR).
• High ripple current capability.
• Low cost.
• High power rating.
• Excellent temperature characteristics.
• Good stability.

Disadvantages

The disadvantages of the 450QXW100MEFC16X35 aluminum electrolytic capacitor include:

• Very limited lifetime.
• High self-heating.
