MPD19 Series: Stacked Polymer Solid Electrolytic Capacitors – Redefining Circuit Core with Superior Performance

In today's electronic devices, where efficiency, reliability, and miniaturization are increasingly prioritized, the stability and purity of power management systems have become crucial to product success. Traditional liquid electrolytic capacitors, due to their inherent high ESR, limited lifespan, and insufficient high-temperature stability, are increasingly unable to meet the demanding requirements of high-end applications. Shanghai YMIN Electronics' MPD19 series of stacked polymer solid electrolytic capacitors is a revolutionary component developed to address this industry transformation. With its ultra-high capacitance density, extremely low ESR, excellent high-frequency performance, ultra-long lifespan, and outstanding temperature stability, it is rapidly becoming the preferred solution in high-end fields such as communications, automotive electronics, industrial control, and aerospace.

I. Core Technology: A Performance Leap from Stacked Structures

The core advantage of the MPD19 series stems from its unique stacked polymer electrolyte technology. Unlike traditional wound structures or ordinary polymer capacitors, it employs a multi-layer design, precisely combining conductive polymers and aluminum materials in a stacked manner. This structural innovation brings several disruptive performance improvements:

1. Extremely high capacitor density and miniaturization advantages: The MPD19 series offers a wide capacitance range from 8.2μF to 560μF and a rated operating voltage of up to 50V within an extremely compact package size (typically 7.3mm x 4.3mm x 1.9mm). This means engineers can achieve greater capacitor energy storage and higher voltage ratings within extremely limited space, providing unprecedented possibilities for miniaturized and thinner device designs.

2. Extremely low equivalent series resistance (ESR) and superior high-frequency characteristics: ESR is a core indicator of capacitor filtering efficiency. The MPD19 series achieves ultra-low ESR at the milliohm level (as low as 4.5mΩ) at 100kHz, which means it can significantly reduce energy loss (manifested as heat) in high-frequency switching power supplies and allow for larger ripple current. The direct benefits are: significantly improved power conversion efficiency, lower output voltage ripple, lower system operating temperature, and a qualitative leap in overall stability and reliability. Its ESR frequency characteristics are flat, maintaining a correction factor of 1.0 even in the high-frequency range of 100kHz to 300kHz, with no performance degradation, perfectly meeting the needs of modern high-frequency switching power supplies.

3. Ultra-long lifespan and excellent environmental adaptability: The MPD19 series guarantees a working life of up to 2000 hours even in extreme high-temperature environments of 105℃. Due to its all-solid-state structure, the risk of liquid electrolyte drying and leakage is completely eliminated. In practical applications, devices typically operate at milder temperatures, allowing the MPD19 to achieve a practical lifespan of tens of thousands of hours, far exceeding traditional capacitors, making it particularly suitable for critical infrastructure requiring 24/7 uninterrupted operation. Its wide operating temperature range (-55℃ to +105℃) and ability to withstand high-temperature and high-humidity environments (60℃, 90-95% RH, 500 hours) demonstrate strong environmental adaptability.

4. Stable Electrical Performance and High Reliability: This series of products features extremely low leakage current (I ≤ 0.1CV), and after 2000 hours of durability testing, its capacity change rate, loss tangent, and leakage current all remain within strictly specified ranges. Furthermore, it can withstand surge voltage impacts up to 1.15 times the rated voltage, enhancing the system's survivability under abnormal conditions.

II. Empowering High-End Applications: How the MPD19 Series Leads Industry Innovation

The superior characteristics of the MPD19 series make it a "core power station" in many cutting-edge technology fields.
