CM1483中文资料EMI Filter with ESD Protection数据手册ONSEMI规格书

描述 Description

CM1483 is an L-C EMI filter array with ESD protection, which integrates two Pi-filters (C-L-C) for the headset speaker. The CM1483 has component values of 100pF-3nH-100pF. The parts include ESD protection diodes on all input/output pins, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD diodes connected to the filter ports safely dissipate ESD strikes of ±8 kV, beyond the maximum requirement of the IEC61000-4-2 international standard. Using the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD, the pins are protected for contact discharges at greater than ±15 kV.

特性 Features

• 2 channels of EMI filtering
• ±15 kV ESD protection (HBM)
• I/O port protection for mobile handsets, notebook computers, PDAs, etc.

应用 Application

• Headset speaker port in mobile handsets
• EMI filtering for data ports in cell phones, PDAs or notebook computers

简介

CM1483属于滤波器的EMI/RFI滤波器（LCRC网络）。由ONSEMI制造生产的CM1483EMI/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。
