Multimedia audio systems in new energy vehicles must maintain high-fidelity sound quality and stability under complex operating conditions. YMIN capacitors, with their unique performance, are an ideal choice for this application. Their core technological advantages are primarily reflected in the following aspects:
1. High capacitance density and low ESR ensure pure sound quality
• Energy supply stability: YMIN capacitors (such as the VHT/NPC series) feature ultra-high capacitance density, storing sufficient energy within a limited space. This provides instantaneous energy support for transient peak currents (such as inrush currents exceeding 20A) in audio amplifiers, preventing audio distortion caused by voltage fluctuations.
• Ultra-low ESR filtering: With ESR values as low as 6mΩ, they effectively filter out power supply ripple noise and reduce interference from high-frequency harmonics on audio signals, ensuring clear and pure mid- and high-frequency sound, making them particularly suitable for reproducing detailed vocals and musical instruments.
2. Temperature Resistance and Long Life to Adapt to the In-Vehicle Environment
• Wide Temperature Stability: YMIN solid-liquid hybrid capacitors (such as the VHT series) operate over a -40°C to +125°C temperature range, withstanding both high and cold engine compartment environments. Their performance variability is minimal, preventing capacitor failure caused by temperature fluctuations.
• Ultra-Long Life Design: A lifespan of up to 4,000 hours (over 10 years in actual use) far exceeds the average lifespan of car audio systems, reducing maintenance requirements.
3. Vibration Resistance and Spatial Adaptability for Optimized Installation
• Mechanical Stress Resistance: AEC-Q200-certified solid-liquid hybrid capacitors (such as the NGY series) feature a vibration-resistant structure, maintaining stable electrode connections during vehicle vibrations and preventing intermittent sound.
• Miniaturized Integration: Chip capacitors (such as the MPD19 series) feature a thin, SSD-like design, allowing them to be embedded directly near amplifier circuit boards, shortening power supply distances and minimizing the impact of line impedance on sound quality.
4. Safety Protection and Energy Efficiency Improvement
• Overload Protection: Withstands 300,000 charge and discharge cycles, preventing capacitor breakdown and system failure during sudden current overloads in the audio system (such as transient power from a subwoofer).
• Energy Efficiency Optimization: Low leakage current (≤1μA) reduces static power consumption, extending battery life in conjunction with new energy vehicle energy management strategies.
Summary: YMIN Capacitors address the three key challenges of new energy vehicle audio systems: power quality, environmental adaptability, and space limitations. For example, its VHT series solid-liquid hybrid capacitors are widely used in surround sound systems in high-end vehicles, significantly improving bass dynamic response and vocal reproduction, providing an immersive audio experience in smart cockpits. As the power demands of in-car entertainment systems grow, YMIN’s continued innovation in voltage resistance and miniaturization will further strengthen its technological competitiveness.
