4、 Selection suggestion: Match brands according to the scene
The following table summarizes the core adaptation areas of mainstream brands:
|Requirement scenario | Recommended brand | Key reasons|
|Mobile fast charging/miniaturization | Murata, Fengbin | Small size MLCC, high frequency low ESR|
|New energy vehicle electronic control | Nichicon, Farah Electronics | Vehicle specification certification, resistant to high temperature vibration|
|Industrial power supply/frequency converter | Ruby, Aihua | High ripple current tolerance, high cost-effectiveness|
|Military/Aerospace | Hongda Electronics, Torch Electronics | Tantalum capacitors/ceramic capacitors, ultra-high reliability|
|Energy Storage/Supercapacitors | Jianghai Shares, Jixing Technology (with Black Peony as a shareholder) | Energy Density>7Wh/kg, Long Cycle Life|
International brands (Murata, Nichicon) have advantages in cutting-edge technology and automotive regulations, while Chinese brands (Aihua, Jianghai) are accelerating their substitution for the mid-range market with production capacity and cost. The future trend focuses on solidification (replacing liquid electrolytes), miniaturization (consumer electronics), and high reliability (new energy/military), and technological iteration will continue to reshape the competitive landscape. When selecting, it is necessary to balance performance requirements and costs. In industrial scenarios, Japanese high-frequency capacitors and domestic main filtering capacitors can be mixed and optimized.
