Applications
The EEE-FC1H3R3R is used as an output filter capacitor in switch-mode power supplies, DC-DC converters, and voltage regulator modules where a 50 V rated, 3.3 µF SMD aluminum electrolytic is required for bulk decoupling and ripple reduction. It also serves as a bypass and decoupling capacitor in motor drivers, LED driver circuits, and industrial automation control boards operating from 24 V or 48 V bus rails. Panasonic FC series capacitors are routinely specified in consumer appliances and audio equipment where compact size, 50 V headroom, and low ESR simultaneously matter.

Frequently Asked Questions
What are the capacitance and voltage ratings of the EEE-FC1H3R3R, and which power supply voltage rails does it suit?
The EEE-FC1H3R3R is rated at 3.3 µF capacitance and 50 V working voltage. These specifications make it appropriate for output filtering on 12 V, 24 V, and 36 V DC bus rails in switch-mode power supplies, where the 50 V rating provides at least a 1.4x derating margin relative to the peak rail voltage, extending capacitor service life.
How does the Panasonic FC series construction of the EEE-FC1H3R3R improve performance in a switching regulator output filter?
The Panasonic FC series uses a low-ESR electrolyte and tightly wound foil construction that reduces equivalent series resistance compared to standard aluminum electrolytics. Lower ESR means less ripple voltage across the capacitor at switching frequencies of 100 kHz to 500 kHz, lower self-heating at rated ripple current, and better transient response when load steps occur on the downstream DC rail.
Can the EEE-FC1H3R3R be assembled using standard SMT reflow soldering, and what is its package format?
The EEE-FC1H3R3R is a surface-mount device in Panasonic's FC SMD package, fully compatible with automated pick-and-place equipment and standard lead-free reflow profiles. The SMD format eliminates through-hole drilling and wave-solder steps, reducing assembly cost and enabling placement on both sides of a PCB in high-density layouts for consumer electronics and industrial control boards.
In a 24 V industrial motor driver, what role does the EEE-FC1H3R3R play in protecting the gate drive supply?
In a 24 V motor driver, the EEE-FC1H3R3R is typically placed on the 15 V gate drive supply rail to filter high-frequency switching noise and supply instantaneous charge during gate turn-on events. Its 3.3 µF capacitance sustains the gate drive voltage during current spikes of several amps lasting a few hundred nanoseconds, while the 50 V rating ensures reliable operation even when the motor back-EMF causes transient bus voltage rises above 30 V.
