The Outstanding Features of the YMIN NP1 Series

The YMIN NP1 series of leaded solid aluminum electrolytic capacitors integrates several core advantages, enabling them to excel in a wide range of applications:

1. Excellent Stability and Reliability

The YMIN NP1 capacitors utilize a solid conductive polymer dielectric, ensuring stable operation in high-temperature environments. Their capacitance typically fluctuates by less than 15% over the full temperature range, significantly outperforming liquid electrolytic capacitors. This stable impedance across a wide temperature range makes them ideal for power supply filtering, effectively providing a stable and sufficient power supply.

2. Long Service Life

The solid electrolyte does not evaporate or expand in high-temperature environments like liquid electrolytes do. At 85°C, solid capacitors can achieve a service life of approximately 50,000 hours (approximately 5.7 years), compared to approximately 8,000 hours (approximately 0.9 years) for liquid capacitors under the same conditions. This represents a service life of approximately six times that of liquid capacitors. This makes the NP1 series particularly suitable for equipment requiring long, continuous operation, such as industrial computers, communications infrastructure, and photovoltaic inverters.

3. Low ESR and High Ripple Current Rating
ESR (equivalent series resistance) is a key metric for capacitor performance. YMIN NP1 capacitors feature extremely low ESR, which means they charge and discharge faster, effectively absorbing the high voltages generated between power lines in a circuit. For example, in modern high-performance CPU power supply circuits, the CPU may switch from a low-power state to a full-load state in less than 5 milliseconds. During this period, NP1 capacitors, leveraging their high-speed charge and discharge characteristics, can instantly deliver high peak currents, ensuring stable CPU operation.

4. High Temperature Resistance and Safety
Solid-state capacitors can withstand temperatures up to 260°C. Even if the capacitor's temperature exceeds its tolerance limit, the solid electrolyte merely melts without causing the metal casing to rupture, making them far safer than liquid electrolytic capacitors.

Actual Application Scenarios

The YMIN NP1 series, with its excellent properties, plays an important role in several key areas:

• Consumer electronics: Widely used in laptops, LCD TVs, 3D monitors, game consoles, and more. In computer motherboards and graphics cards, NP1 capacitors are used in power supply filtering modules for the CPU and GPU, ensuring stable processor operation under high load fluctuations.

• Industrial Applications: Suitable for industrial communication power supplies, professional inverters, CNC and servo systems. In control systems for renewable energy power generation (such as solar and wind power), the long life and high reliability of NP1 capacitors reduce maintenance requirements.

• Automotive Electronics and Transportation: In rail transit, new energy vehicles, and other fields, NP1 capacitors can adapt to complex temperature fluctuations and vibration environments, providing stable power support for critical systems.

• Power Management and Conversion: In secondary filter circuits of devices such as DC-DC converters, communication power supplies, and voltage regulators, the excellent high-frequency, low-impedance characteristics of NP1 capacitors significantly reduce circuit output ripple and heat generation, thereby improving circuit stability and operating life.

Selection and Application Guide

When selecting and using YMIN NP1 series capacitors, please note the following points:

• Circuit Compatibility: Key parameters such as the capacitor's rated capacitance, withstand voltage, ESR, rated ripple current, and operating temperature range should be considered.

• Importance of Polarity Connection: Solid aluminum electrolytic capacitors have polarity. When in use, the anode (positive terminal) must be connected to the positive terminal of the power supply. Reverse connection will damage the capacitor.

• Welding and Installation Precautions: For leaded capacitors, it is recommended to leave a 1.5mm bend in the leads during soldering to relieve stress. The soldering temperature should be kept below 350°C and the soldering time should be less than 3 seconds to avoid overheating and damage to the capacitor.

• Comparison with Liquid Capacitors: Solid capacitors may not be as good as high-quality liquid electrolytic capacitors in terms of low-frequency response. In applications with specific low-frequency response requirements, such as audio circuits, comprehensive considerations are necessary. Furthermore, the voltage resistance of solid capacitors is currently generally capped at around 50V, while liquid capacitors can reach over 500V, requiring caution in high-voltage applications. Solid capacitors are also generally more expensive than liquid capacitors.

Market Prospects

The market for solid aluminum electrolytic capacitors holds promise. The Chinese solid aluminum electrolytic capacitor market was estimated to be approximately 6.2 billion yuan in 2023 and is expected to reach 8.8 billion yuan by 2029. In the global market, production of consumer solid-state capacitors is projected to grow from approximately 19.533 billion units in 2022 to approximately 27.823 billion units in 2028. This growth is driven by the development of the electronic information industry, the upgrading of consumer electronics, industrial automation, automotive electrification, and the widespread adoption of new energy sources, all of which are driving increased demand for the quality, stability, and durability of electronic components.

Summary

YMIN's NP1 series leaded solid aluminum electrolytic capacitors, with their polymer solid electrolyte at their core, offer high stability, long life, low ESR, high ripple current capability, excellent thermal stability, and safety. They are key components in demanding modern electronic devices, enhancing overall performance and reliability.
