SMD Common Mode Chokes SBA

SBA Family

SMD Multi-layer Common Mode Filter

The SBA family of surface mount common mode chokes represents a precision-engineered solution for electromagnetic interference (EMI) suppression in modern electronic systems. These ceramic multilayer EMI filters are designed to minimize noise on power and signal lines while maintaining signal integrity across high-speed differential pairs. As part of Ferrtx’s commitment to excellence in magnetics technology, the SBA series offers reliable performance under demanding environmental conditions.

Key Features
・Efficient EMI filtering for common mode noise with minimal impact on high-speed differential signals
・Ultra-low profile design ideal for compact PCB layouts
・Ceramic-based multilayer construction ensures consistent electrical characteristics
・Non-polarized configuration simplifies assembly and reduces error risk
・RoHS-compliant materials support environmentally responsible manufacturing
・Wide operating temperature range from -40°C to +85°C ensures reliability in diverse environments

Detailed Description
The SBA series includes three distinct models—SBA0302-2-900, SBA0805-4-101, and SBA0504ESD-350Y—each tailored to specific impedance and current requirements. These surface-mount devices provide targeted attenuation at 100 MHz, ranging from 35 to 100 ohms, making them suitable for applications where precise control over electromagnetic emissions is critical. With DC resistance values between 4.0 and 6.0 ohms, these components maintain low insertion loss while effectively suppressing unwanted common-mode signals. Their non-inductive structure supports stable operation even in high-frequency digital circuits such as LVDS, HDMI, MIPI, and USB interfaces. Designed for compliance with global EMI standards like CISPR 32 and EN 55032, they serve as essential elements in ensuring regulatory certification for consumer electronics and industrial equipment alike.

Applications
Ideal for use in laptops, mobile phones, audio systems, and multimedia devices, the SBA family excels in filtering EMI from LVDS data lines, USB 2.0 and IEEE 1394 connections, HDMI/DVI video interfaces, and MIPI camera links. These components are especially valuable in portable electronics where space constraints demand ultra-thin solutions without compromising performance. By integrating a ceramic multilayer structure, the SBA series delivers excellent thermal stability and mechanical robustness, enabling long-term reliability in harsh operating conditions.
