Ferrite Beads and Chips

Ferrite beads are one of the most important components in electronic circuits that help to control the undesirable noise. It acts as a filter, absorbing and dissipating the energy from fast switching signals to prevent it from radiating to other parts of the circuit or interfering with other signals. They are also used to protect against EMI (electromagnetic interference) and RFI (radio frequency interference). The PE-0603PFB121ST is a high-efficiency, low-cost ferrite bead specifically designed for use in RF applications.

Application Field

The PE-0603PFB121ST is a high-efficiency, low-cost ferrite bead designed with a 120Ω DC resistance and a 0-2GHz frequency range. This makes it suitable for use in RF applications such as modems, 802.11b/g/n/ac Wi-Fi devices, Bluetooth devices, GPS receivers, set-top boxes, and audio equipment. It is also suitable for use in automotive electronics, medical equipment, security systems, consumer electronics, and industrial control applications.

Working Principle

The PE-0603PFB121ST ferrite bead works by absorbing and dissipating the electrical energy of fast switching signals. This prevents the signal from radiating and causing EMI and RFI problems in other parts of the circuit. The bead features a very small inductance which allows it to be used for high-speed switching signals.

The bead has a low-resistance high-stability surface for easy soldering that ensures a reliable connection. The bead also features a high thermal shock tolerance so it can handle temperatures from -40°C to +105°C. It is also RoHS (Restriction of Hazardous Substances) compliant, making it suitable for use in various applications.
