Infineon BCM856SH6327: High-Performance Dual Common Mode Choke for EMI Suppression
In the realm of modern electronics, managing electromagnetic interference (EMI) is a critical challenge for designers. Uncontrolled EMI can severely degrade the performance and reliability of electronic systems, leading to malfunctions and compliance failures. Addressing this, Infineon Technologies has developed the BCM856SH6327, a state-of-the-art dual common mode choke engineered to provide superior EMI suppression in a compact and efficient package.
This component is specifically designed to attenuate common mode noise, which is a prevalent type of EMI where unwanted signals appear in-phase on two or more lines. The BCM856SH6327 excels in this role, featuring two independent choke windings on a single core. This dual configuration makes it an ideal solution for differential data lines, such as those found in high-speed communication interfaces (USB, HDMI), power supply systems (DC-DC converters), and automotive networks (CAN, LIN). Its ability to effectively suppress noise while maintaining signal integrity is a key performance advantage.
A standout feature of the BCM856SH6327 is its exceptional high-frequency performance. It offers a broad effective frequency range, providing significant impedance to common mode noise currents across a wide spectrum. This ensures robust suppression of interference that could otherwise disrupt sensitive circuitry. Furthermore, the component is characterized by its low insertion loss for differential signals, meaning desired data signals pass through with minimal attenuation or distortion, while unwanted common mode noise is effectively filtered out.
The device is housed in a compact, surface-mount (SMD) package, making it perfectly suited for space-constrained PCB designs common in today's portable and miniaturized electronics. Its construction ensures high reliability and stability under various operating conditions, including elevated temperatures, which is paramount for automotive and industrial applications. The BCM856SH6327 is not just a filter; it is a critical enabler for achieving compliance with stringent EMC regulations like CISPR 25 and IEC 61000-4-6, simplifying the path to market for new products.
The Infineon BCM856SH6327 stands out as a high-performance, integrated solution for complex EMI challenges. Its dual-channel design, excellent high-frequency suppression, and minimal impact on signal integrity make it an indispensable component for engineers designing reliable and compliant systems in the automotive, industrial, and consumer electronics sectors.
