EMLA100ADA151MF61G

Introduction

Aluminum electrolytic capacitors are among the most ubiquitous of all passive components, due to their relatively large size, low cost, and highly reliable performance. These capacitors are typically cylindrical in shape, with two terminations used for the connection. The most common form is the electrolytic capacitor which has two plates - one aluminum and one carbon, separated by an electrolyte. During operation, the two plates conduct current to each other through the electrolyte, thus allowing energy to be stored or discharged.

EMLA100ADA151MF61G Application Field and Working Principle

The EMLA100ADA151MF61G is one type of aluminum electrolytic capacitor. It is a high temperature, polar, radial leaded, non-solid tantalum capacitor. The capacitor features a case dimension of 8.5 mm diameter by 12 mm length, and a capacitance of 100 µF to 150 µF. The lead diameter is 2.2 mm, and the operating temperature range is -40°C to +105°C.

The application of these aluminum electrolytic capacitors is mainly found in applications with high pulse loading, such as automotive electronic systems, DC-DC converters, power supplies, and UPS systems. Additionally, they are commonly used in the defense and industrial sectors.

The working principle of these aluminum electrolytic capacitors is based on the principle of electrical double layers. This is when an electric field is formed between two parallel plates of conductive materials which are immersed in an electrolyte. This field produces a set of charged layers that creates a capacitance which is proportional to the area of the plates and the permittivity of the electrolyte material.

The capacitor uses an aluminum oxide or tantalum oxide dielectric layer which allows the capacitor to function satisfactorily at high temperatures and voltages. This also gives the device excellent volumetric efficiency, as well as the ability to operate in the -40°C to +105°C temperature range.
