Matsushita Electric Industrial Co., Ltd. has developed a vibration-resistant, patch-type conductive polymer hybrid aluminum electrolytic capacitor specifically designed for vehicle ECU (Electronic Control Unit) power supply circuits in HEVs (Hybrid Electric Vehicles), EVs (Electric Vehicles), and conventional gasoline vehicles. This innovative component was launched into mass production in December 2017, marking a significant advancement in automotive electronics.
As the demand for improved fuel efficiency and stricter environmental regulations continues to grow, the number of ECUs installed in modern vehicles is increasing. Along with the rise of mechatronics, there is a growing need for smaller, more durable components that can withstand harsh conditions. This has led to higher demands for capacitors used in ECU power supply circuits—capacitors that not only stabilize voltage but also filter out electrical noise. To meet these challenges, Matsushita Electric introduced the first conductive polymer hybrid aluminum electrolytic capacitor with a diameter of 6.3mm, offering exceptional vibration resistance of 30G, significantly surpassing its previous model, which had a vibration resistance of only 10G.
This new product brings several key advantages:
1. **Compact Design with Enhanced Vibration Resistance**
- Available in two sizes: 6.3mm diameter × 6.1mm height and 6.3mm diameter × 8.0mm height
- Provides industry-leading vibration resistance of 30G, ideal for reducing both size and mechanical stress in ECUs
2. **Simplified Manufacturing Process**
- Eliminates the need for additional reinforcement during board mounting
- Reduces reliance on adhesives, helping customers streamline their production workflows
3. **Improved Solderability**
- Features Panasonic’s proprietary auxiliary terminal design for more reliable and stable solder joints
This capacitor is ideally suited for use in HEV and EV power supply circuits, as well as high-performance ECU systems in gasoline vehicles and electromechanical integrated control units. With its advanced design and performance, this product represents a major step forward in the development of robust, compact, and efficient electronic components for the automotive industry.
