SEUL, Corea del Sur, 17 de mayo de 2023 /PRNewswire/ -- Samsung Electro-Mechanics anunció el día 16 que logró alcanzar la capacidad más alta de la industria en términos de MLCC de alta presión aplicable a vehículos eléctricos y comenzó a apuntar al mercado al expandir su línea de componentes electrónicos de automóviles de alta gama.

Samsung Electro-Mechanics develops the world's highest capacity MLCC for electric vehicles.

Los MLCC desarrollados esta vez son productos que tienen las características de clase 250V 33nF (nanofaradio) con baja tasa de cambio de capacitancia según la temperatura y clase 100V 10µF (microfaradio) para 125℃ y son productos con la capacidad más alta de la industria en términos de alta presión MLCC en la misma clase de tensión.

Cada producto se utiliza en sistemas eléctricos y faros LED, que son dispositivos clave para los vehículos eléctricos.

  * Faradio (símbolo: F): Unidad que representa la capacidad eléctrica

Los vehículos eléctricos funcionan con sistemas de baterías de alto voltaje, como los sistemas de gestión de baterías (BMS) y los cargadores a bordo (OBC).

Los MLCC utilizados en vehículos eléctricos deben poder soportar los altos voltajes de salida transmitidos desde la batería para una carga y suministro de energía ultrarrápidos.

Además, a medida que aumenta la cantidad de componentes electrónicos utilizados en los vehículos eléctricos, los semiconductores también deben tener características de alta capacidad para que puedan operar de manera estable.

El producto de clase 250V · 33nF desarrollado esta vez cuenta con la capacidad más alta de la industria al mismo nivel de voltaje. 22nF fue la capacidad más alta para los productos de clase de 250V existentes.

Este producto mejora la estabilidad de la batería al eliminar el ruido de alta frecuencia dentro del módulo de la batería mientras tiene la durabilidad para soportar altos voltajes.

Además, el producto clase 100V · 10µF se utiliza en faros LED para vehículos eléctricos y se ha duplicado su capacidad eléctrica respecto al producto anterior.

Los semiconductores utilizados en los faros LED requieren un alto consumo de energía, por lo que son esenciales los MLCC de alta capacidad que pueden almacenar una gran cantidad de energía y suministrarla a los semiconductores de manera rápida y estable mientras tienen una durabilidad de alto voltaje.

En general, es difícil para los MLCC satisfacer las características de voltaje y capacitancia al mismo tiempo. El diseño de dieléctricos más gruesos para aumentar las características de voltaje reduce la cantidad de electrodos internos que se pueden apilar, lo que dificulta aumentar la capacidad.

Samsung Electro-Mechanics ha logrado una alta capacidad al refinar dieléctricos como materia prima central en forma de polvo fino a nivel nanométrico.

La compañía también explicó que su método patentado de recubrimiento de superficies minimiza la aglomeración entre los polvos, lo que permite un funcionamiento estable a altos voltajes.

Mientras tanto, los MLCC desarrollados esta vez cumplen con AEC-Q200, un estándar de prueba de fiabilidad para componentes electrónicos de automóviles, lo que les permite usarse en otras aplicaciones como ADAS, carrocería, chasis e información y entretenimiento en vehículos.

El consejero delegado de Samsung Electro-Mechanics, Chang Duckhyun, dijo que "Samsung Electro-Mechanics ha establecido toda la línea para MLCC automotriz mediante el desarrollo de productos para vehículos eléctricos" y que "Samsung Electro-Mechanics desarrollará y fabricará materias primas básicas para MLCC por su cuenta para mejorar la competitividad tecnológica y ampliar su participación en el mercado de dispositivos electrónicos MLCC mediante la internalización de las instalaciones y el fortalecimiento de la capacidad de producción."
