                                                M550B507K040AH Overview
In order to maintain high efficiency, the ESR (Equivalent Series Resistance) should remain at 50mOhm @ 100kHz.Capacitance 500μF governs its operation.Voltage - Rated AC is -55°C~105°CV.High efficiency is possible because of the voltage - Rated at 40V.Operating at [0.445 11.30mm°C]°C seated height makes it stable.
M550B507K040AH Features
a 50mOhm @ 100kHz ESR (Equivalent Series Resistance)
with a capacitance of 500μF
an AC voltage of -55°C~105°C
the voltage rating of 40V
