Panasonic Electrolytic Capacitor Distributor | FR Series

BeiLuo supplies genuine Panasonic aluminum electrolytic capacitors, the capacitors that filter, smooth and store energy in power supplies, motor drives and industrial equipment. An aluminum electrolytic capacitor packs a large capacitance into a small can, which makes it the workhorse of the DC bus and the output filter, but it is also a wear-out component whose life is set by its temperature and its ripple current. The Panasonic FR series is a radial-leaded electrolytic with a long endurance of 5000 to 10000 hours at 105 degrees Celsius, a low impedance and a high ripple current, so it suits a compact switch-mode supply or a motor-control board where a standard capacitor would run too hot. The series covers 6.3 V to 100 V and a wide capacitance range, with a tolerance of plus or minus 20 percent, in case sizes from 5 mm to 18 mm diameter, and it is available in bulk, ammo-taped and radial-taped packaging for automatic insertion. Choosing the right part means matching the voltage, the capacitance and the ripple current to the circuit, and then checking that the case temperature and the ripple current keep the capacitor within its rated life, because an electrolytic that runs hot loses life quickly. The FR series is used in switching power supplies, inverters, motor drives, lighting and industrial electronics. BeiLuo holds mainstream FR values in stock and ships every capacitor with an import declaration, a certificate of origin and a RoHS file, and our FAE team helps with the ripple-current and lifetime estimation.
