Murata Ferrite Bead (Chip Ferrite Bead), 1.6 x 0.8 x 0.8mm (0603), 647Ω impedance at 25 MHz, 1000Ω impedance at 100

The Murata BLM18SP series chip ferrite bead is designed to function nearly as a resistor at noise frequencies, which greatly reduces the possibility of resonance and leaves signal wave forms undistorted. It is effective in circuits without stable ground lines. It can be used in high current circuits due to its low DC resistance. It has impedance of 1000 ohm.

Nickel barrier structure of the external electrodes provides excellent solder heat resistance
Operating temperature range from -55 °C to 125 °C
Does not need a connection to ground
