Aluminum-polymer capacitors (Al-poly) are a type of non-polarized components that are commonly used in electronic equipment, AC and DC circuits. They are also known as non-polarized electrolytic capacitors since they consist of two metalized aluminum electrodes with a layer of polymer material between them. The RNS1C680MDN1KX, from the EPCOS family of capacitors, is an aluminum-polymer capacitor designed for use in automated control and power applications.

As a cost-effective alternative to electrolytic capacitors, Al-poly capacitors offer a higher capacitance, lower voltage, and better temperature stability than their counterparts. Furthermore, the absence of a dielectric polarization layer makes aluminum-polymer capacitors less prone to leakage current, phenomena and other degradation effects. This explains why this product from EPCOS is particularly suited for energy-efficient, process control applications.

The RNS1C680MDN1KX is a surface-mount device (SMD) with an X7R dielectric and a nominal capacitance value of 680 μF. It has a dissipation factor of 0.25 and an axial lead distance of 12.5 mm. Its maximum allowable ripple current is 50 mA and its rated temperature range is -40 to 85 °C. UN-sprung, the device is just 4.8 x 12.2 x 17.2 mm in size, making it ideal for tight spaces and high-density applications.

RNS1C680MDN1KX aluminum-polymer capacitors are designed for use in critical circuits where high pulse performance, long shelf life, and high surge current capacity are necessary. For example, it can provide exceptionally strong line and load regulation for electromechanical switching (SSR) circuits, and can act as an energy reservoir with its high capacitance value. Moreover, the device is designed to reduce solution size, saving on board space. It is compatible with standard SMT automated assembly systems and its low profile makes it an attractive choice for robust, miniaturized power applications.

In terms of its working principle, the RNS1C680MDN1KX acts as a two-terminal capacitor. When a DC voltage is applied to a capacitor, a charge builds up on each of its two plates, which creates an electric field between them. This electric field is responsible for storing energy and permitting charge to move between the two plates. When the voltage is too high, the electric fields around the two plates will collapse and current will flow, allowing the excess charge to be safely discharged.

The RNS1C680MDN1KX is a popular choice for a wide range of automated control and power-management applications due to its high capacitance, long shelf life, and robust construction. Its small size and low profile allows for its use in space-constrained and high-density applications, while its high energy storage capacity and low leakage current provide reliable performance and long-term durability. As a result, the RNS1C680MDN1KX is a versatile and economical solution for modern power management needs.
