It has a very thin profile, making it ideal for applications that require a small physical footprint. It is also capable of withstanding high temperatures, vibrations, and drops, making it suitable for a wide range of environments. Additionally, it has a high-temperature endurance range of up to -55°C to +125°C, making it perfect for automotive electronics and consumer products.

The SPSX151M04R capacitor is a very reliable and stable solution for any applications where high-signal processing, low ESR and long-term quality are required. It is designed to provide high current densities and is designed to handle high-voltage ripple and transients without fail. Additionally, its capability to withstand high-temperatures gives it great advantages in many high-temperature industrial applications.

Working Principle

Aluminum-polymer capacitors are designed to provide an enhanced performance in both high frequency applications and high temperature applications. The working principle involves a combination of both dielectric materials and active substances. The dielectric layer is composed of an aluminum foil or an electrostatic absorbing polymer, which separates the electrodes from each other. The active materials are also known as the "catalyst" in the electrolyte, which enables the capacitance to be increased.

The SPSX151M04R capacitor is designed to be capable of withstanding high temperatures and shock, making it suitable for a variety of environmental conditions. It is constructed with a special "foil-in-foil" configuration, with the dielectric layer made from an ultra-thin polyethylene material that is applied to the metal plates. This configuration allows the capacitor to have a high storage capacity. Additionally, it has an external metal covering around the core, which acts as an EMI shield and provides protection against high-voltage spikes.

The SPSX151M04R capacitor also features a special construction method. It is designed to have an extremely low ESR, allowing for more power supply efficiency and lower noise. The construction of the SPSX151M04R also provides high leakage current performance, eliminating potential concerns related to board design, power supply, and grounding. Additionally, the capacitor is designed to have a long-life and shelf-life, which makes it suitable for long-term use in various applications.

In conclusion, the SPSX151M04R capacitor is a great choice for applications such as automotive electronics, consumer products, automotive ECUs, and renewable energy systems. It is designed with a very thin profile and a long shelf-life, providing high power supply efficiency and low noise. Its combination of dielectric materials and active substances makes it suitable for high-temperature, high-frequency applications, as well. The special construction method also helps to provide an extremely low ESR and high leakage current performance.
