EEU-FR1H101
Panasonic EEU-FR1H101 FR aluminum electrolytic capacitor, 100 uF at 50 V, low impedance with a 6000-hour life at 105 C.
The EEU-FR1H101 is a Panasonic FR series radial-leaded aluminum electrolytic capacitor rated 50 V and 100 microfarads, in an 8 by 11.5 mm case. It is a low-impedance, high-ripple-current part with an endurance of 6000 hours at 105 degrees Celsius, which makes it suitable for a compact switch-mode power supply, a motor-control board or an LED driver where a standard capacitor would run too hot and fail early. The FR series is designed to pack a large capacitance and a high ripple-current capability into a small can, so it can replace a larger or hotter part without changing the circuit, and its low impedance keeps the internal heating down at the switching frequency. The tolerance is plus or minus 20 percent, the rated ripple current at 100 kHz is about 870 milliamps, and the part is available in bulk, ammo-taped and radial-taped packaging for automatic insertion. Choosing the right electrolytic means matching the voltage, the capacitance and the ripple current to the circuit, then checking that the case temperature and the ripple current keep the capacitor within its rated life, because the life of an electrolytic roughly doubles for every ten degrees below its maximum temperature. The FR series is used in switching supplies, inverters, motor drives, lighting and industrial electronics. Every capacitor BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file, and mainstream values are held in stock.
FAE Professional Review
The EEU-FR1H101 is a 50 V, 100 microfarad FR-series capacitor for a compact supply, and its value is the combination of a low impedance and a 6000-hour life at 105 C. Size it on ripple current at the hot case temperature, not on capacitance alone, and keep it away from the hottest parts of the board to win back life.

Frequently Asked Questions
What is the EEU-FR1H101 rated for?
It is a 50 V, 100 microfarad radial aluminum electrolytic capacitor in an 8 by 11.5 mm case, with a tolerance of plus or minus 20 percent, a rated ripple current of about 870 milliamps at 100 kHz and a 6000-hour endurance at 105 C.
Confirm the ripple current at your hot case temperature.
How long will it last in my supply?
The endurance is 6000 hours at the maximum rated temperature with the rated ripple current, and the life roughly doubles for every ten degrees below that. If the capacitor runs at 85 degrees instead of 105, its life is several times longer, so cooling it is the cheapest way to extend it.
Our FAE team can estimate the life at your temperature.
Is the capacitor genuine and in stock?
BeiLuo supplies factory-traceable capacitors through Panasonic authorized channels, with import declaration, certificate of origin and RoHS files on every order. Mainstream values are normally in stock.
