BLM31AF700SN1L Datasheet PDF - muRata

●The Murata BLM31AF series are EMIFIL chip ferrite beads for suppressing high frequency noise in general signal line application. These chip ferrite beads are designed for reducing the possibility of resonance to provide undistorted signal waveform. EMIFIL chip ferrite beads do not require connection to ground so they are effectively used in circuits without stable ground lines. The nickel barrier structure of the external electrodes provides excellent solder heat resistance. BLM31AF series ferrite beads generates impedance from relatively low frequencies, therefore they are effectively used for noise suppression in wide frequency range (30MHz to several hundred MHz).

● EIA 1206 standard chip size

● Miniaturized ferrite beads

● Effective at low impedance line

● Available in selective impedance range values at 100MHz

● Operating temperature range -55°C to 125°C
