To assist driver's safety and convenience, ADAS(Advanced Driver Assistance System) technology continues to evolve with improvement of the performance of ADAS SoCs (System on Chips).
The enhancement of SoC performance leads to increased power consumption. To ensure the stable operation of SoCs in high-power/high-frequency environments, high-capacitance and Low ESL MLCCs are required.
Samsung Electro-Mechanics provides high-capacitance, Low ESL MLCCs applicable to ADAS SoCs. They are as follows:

Second Solution: Low ESL(3T) MLCC
As ADAS SoCs evolve, there is a growing need for MLCCs which offer both high capacitance and low ESL characteristics for stable SoC operations under high power/high frequency circumstances. As the switching frequency of SoCs increases, loop inductance generates high-frequency noise, which is suppressed by MLCCs.
Low ESL(3T) MLCCs excel at mitigating high-frequency noise, enabling stable power supply with fewer devices compared to normal MLCCs. This makes them an excellent solution in circuits with limited board space.
In addition to meeting the electrical requirements of this application, Low ESL(3T) MLCCs can achieve space savings of over 30%.
