Key Features
- 4.7 µF capacitance at 35 V rated voltage with ±20% tolerance for robust filtering and decoupling in power supply circuits
- SMD (surface-mount device) package enables automated pick-and-place assembly and high-density PCB layouts compared to through-hole alternatives
- Full reel packaging supports high-volume production runs with consistent tape-and-reel pitch for uninterrupted SMT assembly lines
Applications
The EEE-FC1V4R7R is commonly used as a bulk decoupling and filtering capacitor in DC-DC converters, power management modules, and voltage regulator output stages operating up to 35 V. Its 4.7 µF capacitance value makes it effective for smoothing ripple currents in switching frequencies from 100 kHz to 1 MHz in compact consumer electronics and industrial power supplies. The SMD form factor also suits audio amplifier input coupling and signal bypass applications in space-constrained designs.

Frequently Asked Questions
What are the key electrical ratings of the Panasonic EEE-FC1V4R7R aluminum electrolytic capacitor?
The EEE-FC1V4R7R is rated at 4.7 µF capacitance and 35 V working voltage with a ±20% tolerance. These parameters make it suitable as an output filter capacitor in DC-DC converters and LDO regulators operating up to 35 V, where bulk capacitance in the 4 µF to 10 µF range reduces output voltage ripple below 50 mV in typical switching designs.
How does the SMD package of the EEE-FC1V4R7R benefit PCB assembly compared to through-hole capacitors?
The surface-mount package of the EEE-FC1V4R7R eliminates the need for drilled PCB holes, reducing board area by up to 30% compared to a radial through-hole 4.7 µF capacitor. It is compatible with standard reflow soldering at peak temperatures up to 260°C and supports automated pick-and-place assembly at line speeds over 10,000 components per hour, improving throughput in high-volume production.
Which power supply topologies benefit most from using a 4.7 µF, 35 V aluminum electrolytic capacitor like the EEE-FC1V4R7R?
Buck converters and synchronous rectifiers operating between 12 V and 28 V rails particularly benefit from the EEE-FC1V4R7R's 4.7 µF at 35 V rating. The capacitor provides bulk energy storage that limits output voltage droops below 100 mV during fast load transients of 500 mA or more. It is also used in flyback converter secondary stages where hold-up time of several milliseconds is required.
Is the EEE-FC1V4R7R available on a full reel, and what quantities does a reel typically contain?
Yes, the EEE-FC1V4R7R is supplied on a full reel in standard tape-and-reel packaging, which typically contains 2,000 units per reel for SMD aluminum electrolytic capacitors of this size. Full-reel ordering minimizes per-unit cost and ensures continuous feeding into SMT pick-and-place machines without manual reloading, making it the preferred format for production runs exceeding 500 units.
