EMIF06-USD05F3中文资料6-line EMI filter and ESD protection for SD card, mini-SD card and micro-SD card interfaces数据手册ST规格书

描述 Description

The EMIF06-USD05F3 is a 6-line EMI filter dedicated to SD, mini-SD and micro-SD card applications. It provides an efficient attenuation at 900 MHz to reduce or suppress the antenna de-sense. This filter includes ESD protection circuitry, which prevents damage to the protected device when inserting the card. Pull-up resistors are not integrated inside the chip, hence the EMIF06-USD05F3 gives the flexibility to customers to use controllers with embedded resistance. This 6-line IPAD™ is packaged into a flip-chip solution, saving PCB space.

简介

EMIF06-USD05F3属于滤波器的EMI/RFI滤波器（LCRC网络）。由制造生产的EMIF06-USD05F3EMI/RFI 滤波器（LC，RC 网络）该系列产品将几种无源元器件集成到单个装置中，可用于产生电流的频率依赖性阻抗。尽管有其他类型，但大多数都是用于抑制不必要高频信号传输的低通型，否则可能会导致干扰或意外操作。
