VP4 Series Conductive Polymer Solid Aluminum Electrolytic Capacitors: The Reliable Power Core of Modern Electronic Devices

In today's rapidly developing electronics industry, miniaturization, efficiency, and reliability have become key industry development priorities. Shanghai YMIN Electronics' VP4 Series Conductive Polymer Solid Aluminum Electrolytic Capacitors are innovative products designed to meet this trend, providing a stable and reliable power management solution for a wide range of electronic devices.

Groundbreaking Product Design

The VP4 Series capacitors utilize advanced conductive polymer technology, representing the latest advancements in aluminum electrolytic capacitor technology. Compared to traditional liquid electrolytic capacitors, the VP4 Series offers revolutionary structural improvements, using conductive polymer as the solid electrolyte. This eliminates potential issues with liquid electrolytes, such as leakage, dry-out, and poor high-temperature stability.

One of the most striking features of this series is its ultra-thin design. At only 3.95mm in height, it is one of the thinnest products of its kind on the market. This compact design makes the VP4 Series particularly suitable for space-constrained applications, furthering the possibilities for miniaturization in modern electronic devices. Furthermore, the product utilizes surface mount technology (SMT), is compatible with high-temperature lead-free reflow soldering processes, and fully complies with RoHS environmental directives, meeting the dual environmental and process requirements of modern electronics manufacturing.

Excellent Technical Performance

The VP4 series capacitors offer excellent electrical performance, with a wide operating temperature range (-55°C to +105°C), rated operating voltages from 6.3V to 35V, and a capacitance range from 10μF to 220μF (at 20°C, 120Hz). The capacitance tolerance at room temperature is controlled within ±20%, ensuring consistency and reliability in batch production.

Of particular note is the VP4 series' low equivalent series resistance (ESR), demonstrating extremely low impedance values ​​under 100kHz testing. Low ESR directly benefits the capacitor's performance at high frequencies, effectively reducing power loss and improving overall device efficiency.

Strict Reliability and Durability Testing

To verify the product's long-term reliability, YMIN subjected the VP4 series to rigorous durability testing. After applying the rated working voltage for 2000 hours at 105°C, the product maintains excellent electrical performance: capacitance change does not exceed ±20% of the initial value, ESR does not exceed 200% of the initial specification, loss tangent is also within 200% of the initial specification, and leakage current remains consistently below the initial specification.

High-temperature and high-humidity environmental testing further demonstrates the VP4 series' environmental adaptability. Under the harsh conditions of 60°C and 90%-95% relative humidity, all product parameters remain within specified ranges. This robust environmental tolerance makes the VP4 series particularly suitable for use in harsh operating environments, such as automotive electronics and industrial control.

Wide Applications

The superior properties of the VP4 series conductive polymer solid aluminum electrolytic capacitors make them important in a wide range of applications.

In automotive electronics, VP4 capacitors can withstand extreme temperature fluctuations and vibration shock in the vehicle environment, providing stable power filtering and energy storage for critical systems such as engine control units (ECUs), in-vehicle infotainment systems, and advanced driver assistance systems (ADAS). Its solid-state structure completely eliminates the risk of performance degradation caused by vibration in liquid electrolytic capacitors, significantly improving the reliability of automotive electronic systems.

In AI data servers and communications equipment, VP4's low ESR characteristics are particularly important for handling high current ripple. Modern server power supplies require high current and low noise. VP4 capacitors effectively filter high-frequency noise on power lines, providing clean power to core computing units such as CPUs and GPUs. Its high ripple current handling capability (after optimizing the frequency correction factor) ensures stable operation under high load conditions.

In robotics and drone applications, VP4's ultra-thin design and lightweight features meet the stringent space and weight requirements of these devices. Furthermore, its wide operating temperature range ensures reliability in a wide range of environmental conditions, from the high temperatures of industrial sites to the low temperatures of outdoor applications.

In new energy applications such as solar inverters and energy storage systems, VP4 capacitors provide efficient DC support and noise filtering for power conversion circuits. Its long lifespan perfectly matches the high service life requirements of new energy equipment, reducing system maintenance and overall lifecycle costs.
