Aluminum-polymer capacitors are components of electrical systems used to store and supply electric power, which are composed of conductive metallic layers and polymer layers with a very thin intervening dielectric to create an effective electrical storage site. These capacitors are available in both high- temperature and low- temperature types to suit a variety of capacitor needs within electrical systems and have been in use since the 1990s. The EEF-CD1B100R belongs to this category of capacitors and is an advanced capacitor offering a temperature range of -40°C to +125°C and a wide operating voltage of 1~100V.

The EEF-CD1B100R\'s application field lies primarily in extreme environments such as automobiles, engines, and aerospace. This capacitor is specifically designed to operate in the harsh, lightning-fast changes and high temperatures of automotive engines and aerospace applications, making it the perfect choice for system components that require efficient storage and transfer of electric power over long periods of time. Its power efficiency, long-lasting durability, and low ESR (effective series resistance) make it perfect for these applications.

The polymer used in the EEF-CD1B100R is a special type called Low-ESL (Ellipsoidal Surface Layer), which is more resistant to extreme temperature fluctuations and allows the capacitor to remain stable at both high and low temperatures. Also, even when the temperature increases, the ESL of the EEF-CD1B100R remains lower compared to traditional aluminum-polymer capacitors. This ensures higher dielectric constants and greater power efficiency over time.

As for its working principle, the EEF-CD1B100R is an insertion capacitor wherein an electrode of conductive material is inserted between two dielectric down thick insulating layers. When an electric charge is applied to the electrodes, the electric field creates a field of repulsion that starts to build up and store energy in the capacitor. During its operation, the charge stored in the capacitor is balanced by the opposing electric field, resulting in the higher dielectric constants and greater power efficiency.

These characteristics make the EEF-CD1B100R the perfect capacitor for the automotive, engine, and aerospace industries. Its low ESR and high power efficiency make it ideal for longer life, more efficient storage and transfer of electrical energy over long periods of time. Its special Low-ESL polymer construction allows it to remain stable in extreme temperature changes, making it ideal for applications where temperature-resistant components are necessary.
