Coilcraft Unveils 0805 Wire-wound Ferrite Beads
26 June, 2023
The 0805PB Series offers extremely low DCR that is optimized for high-frequencynoise suppression on high current power supply lines
Coilcraft announced new release of its 0805PB Series automotive small size wire-wound ferrite beads. The series features robust mechanical structure, and is approved for the automotive applications and harsh environments standard AEC-Q200 Grade 1 (–40°C to +125°C).
Ferrite beads, or ferrite chokes, are used as low pass filters to eliminate high frequency noise while allowing low frequency signals or DC current to pass through a circuit. The noise may come from any number of sources including high-frequency switching noise from a power-supply circuit or RF noise in an RF signal-isolation circuit that must be minimized to ensure both signal integrity and antenna efficiency.
Wirewound ferrite beads also provide lower DC resistance (DCR) and higher current ratings without core saturation, resulting in the highest possible performance in the smallest size
The 0805PB Series offers extremely low DCR that is optimized for high-frequency (up to 1.7GHz) noise suppression on high current power supply lines of up to 4.4 Amps. The new products provide wider spectrum of suppression than traditional ferrite beads, with inductance ranging from 0.1μH up to 3.6μH (±20% Tolerance). It is RoHS compliant , halogen free, and can be stores in wide range of tempertures (–40°C to +140°C).
Coilcraft is represented and supported in Israel by Elina Electronic Engineering Group.
