Market Factors Accelerating the Shift to Soft-Termination
Growing Demand for Fail-Safe Designs
The adoption of soft-termination products is strongly recommended, particularly in battery lines and low-voltage, high-power lines
Increased Importance of Countermeasures for Board Flexure
With the adoption of thicker boards for higher power and the integration of heavy, large components, countermeasures against board flexure have become critical priority.
Smaller Stress from Smaller, Higher-Performance ECUs
High-density mounting not only increases thermal stress on the board but also causes rapid temperature changes (thermal shock) due to the introduction of advanced liquid-cooling systems.
Replacement of Ta/Al Polymer Capacitors
To ensure a stable supply of components and reduce mounting area, there is a growing trend. Toward replacing conventional polymer capacitors with highcapacitance MLCCs. In such cases, soft-termination is increasingly selected to reduce the risk of cracking
