EMI/RFI Filters (LC, RC Networks) are employed in electronic circuits and systems in order to inhibit high frequency electromagnetic interference or radio-frequency interference (EMI/RFI). Such filters are composed of a basic combination of inductors (L) and capacitors (C). Products such as the IP4254CZ8-4-TTL (IP4254) provides EMI/RFI filtering in both directions (ie. both transmitting and receiving, or bidirectional).

Introduction to the IP4254

The IP4254CZ8-4-TTL (IP4254) is a four-line, bidirectional Thyristor Transient Voltage Suppressors designed to protect electronic equipment from high-voltage transients. The IP4254 employs low pass LC networks to filter out electric and radio frequency interference (EMI/RFI). It is available in a variety of package styles, including surface mount, allowing for easy installation. The IP4254 is constructed of the highest quality dielectric materials, and is designed to withstand both temperature and voltage extremes.

Applications of the IP4254

The IP4254 is most suitable for low-impedance applications, such as power supply, output and input voltage protection, line cables, automotive applications, motor drive systems, railway systems and portable devices. This device can also be used in EMC testing and certification, as well as in the telecom, medical and industrial sectors.

Working Principle of the IP4254

The IP4254 utilizes a low-pass filter to reduce the amount of EMI/RFI that is transmitted through an electronic system. This filter is a combination of inductors and capacitors arranged in a series cathode-common configuration, which creates a low-impedance narrow bandwidth filter. The series arrangement of the inductor-capacitor connected elements act in parallel to shunt energy, thus providing the desired filtering effect.

The IP4254 is constructed of high-grade dielectric materials to ensure maximum performance and reliability. Its capacitors and resistors are rated to withstand the harshest conditions. The IP4254 is also designed to meet various industry and country standards and is fully compliant with the latest EMI/RFI regulations.

Conclusion

The IP4254CZ8-4-TTL (IP4254) is an excellent choice for EMI/RFI filtering in low-impedance applications. Its effective low-pass filter acts in series on both the signal input and output, making it ideally suited for both bidirectional data protection and immunity. IP4254 is a reliable, cost-effective solution that is designed to withstand high temperatures and voltage extremes.
