Posted May 27, 2025 by YMIN-CAPACITOR

Despite the multiple challenges in the development of vehicle refrigerators, YMIN capacitors significantly enhance their performance and reliability with features such as low ESR, excellent surge current resistance

 
With the rapid development of new energy vehicles, onboard refrigerators are gradually transitioning from a luxury in traditional fuel-powered cars to an essential accessory for modern travel. They not only offer drivers the convenience of enjoying fresh beverages and food anytime but also serve as a key symbol of the intelligence and comfort of new energy vehicles. Despite their growing popularity, onboard refrigerators still face challenges such as difficult startups, unstable power supply, and low energy efficiency, driving the demand for higher standards in capacitors used within their controllers.

YMIN capacitor application advantages and selection recommendations

Liquid lead aluminum electrolytic capacitors are recommended for power conversion:


High Surge Current Resistance: Helps the power system maintain stable voltage output during load fluctuations, reducing voltage drops during startup and minimizing the impact of peak currents on other onboard electronic devices.
High Ripple Current Endurance: Low-impedance, high-frequency capacitors can withstand significant ripple currents without overheating, ensuring long-term stable operation of vehicle refrigerators.
Long Lifespan: Excellent high-temperature tolerance and anti-vibration performance enable capacitors to operate reliably in harsh environments, reducing maintenance needs.

YMIN capacitor application advantages and selection recommendations


For the car refrigerator control part, YMIN provides two solutions for engineers to choose suitable capacitors according to different circuit designs.


Minimal Capacitance Reduction at Low Temperatures: Vehicle refrigerators require a high surge current at startup, but traditional capacitors often experience severe capacitance loss in low-temperature conditions, compromising current output and causing startup difficulties. YMIN liquid SMD aluminum electrolytic capacitors feature minimal capacitance reduction at low temperatures, ensuring stable current support and smooth refrigerator operation even in cold environments.
Replacement for Traditional Leaded Capacitors: Compared to traditional leaded capacitors, liquid SMD aluminum electrolytic capacitors are better suited for automated production lines, enhancing production capacity and consistency while reducing human error, enabling fully automated manufacturing.


Low ESR: Reduces the capacitor's own energy loss when powering vehicle refrigerators, enabling more efficient use of onboard power. This minimizes unnecessary energy waste, ensuring stable refrigerator operation and reliable cooling performance under the same power input conditions.
High Ripple Current Resistance: Onboard power supplies often exhibit ripple currents due to fluctuations. Polymer hybrid SMD aluminum electrolytic capacitors have excellent ripple current resistance, effectively handling unstable current inputs and providing steady power to vehicle refrigerators, preventing cooling instability or malfunctions caused by current fluctuations.
Strong Overvoltage Resistance: Automotive electrical systems may experience voltage fluctuations or transient overvoltage conditions. Solid-liquid hybrid capacitors offer robust overvoltage resistance, with surge voltage tolerance exceeding 1.5 times the rated voltage. This protects the refrigerator’s circuitry from damage caused by these voltage variations.

Summarize

Despite the multiple challenges in the development of vehicle refrigerators, YMIN capacitors significantly enhance their performance and reliability with features such as low ESR, excellent surge current resistance, and high ripple current endurance. Additionally, the compact design improves space utilization.
