CIG21L inductors, coils, choke 系列
Samsung Electronics Co., Ltd.功率芯片屏蔽多层电感器系列
三星生产的CIG21L系列是一种适用于高频应用的功率芯片屏蔽多层电感。这些电感常用于开关电源、DC/DC转换器和其他需要紧凑尺寸和高效率的电源管理电路中。它们采用屏蔽设计，有助于减少电磁干扰（EMI），因此特别适合对EMI合规性有要求的应用场合。
值得注意的是，它们在狭小空间中的性能表现优异。当工程师需要能够在非常小的外形尺寸下仍能可靠工作的电感时，往往会选用这些电感。屏蔽设计也有助于降低辐射发射，这对于密集的电子组装尤为重要。另一个实用观察是其坚固性；它们能够处理高电流，并能在恶劣的热条件下高效运行，因此适用于高功率应用。如果你正在从事与高频开关调节器或功率转换电路相关的工作，CIG21L系列绝对值得考虑。
