Key Features
- 47µF capacitance at 6.3V rated voltage provides effective energy storage and bulk decoupling for low-voltage DC power rails
- ±20% capacitance tolerance suits non-critical filtering and decoupling roles where tighter tolerance is not required
- SMD surface-mount form factor enables automated reflow soldering and high-density PCB layouts in consumer electronics
- Full reel packaging minimizes handling and supports uninterrupted automated pick-and-place production runs at high volume
Applications
The Panasonic EEE-FK0J470R is commonly used as a bulk energy storage and decoupling capacitor on 5V and 3.3V power rails in smartphones, tablets, wearables, and IoT devices where compact board area is at a premium. Its 6.3V rating and 47µF capacitance make it ideal for output filtering on low-dropout regulators (LDOs) and DC-DC converters in portable consumer electronics. Full reel delivery supports high-volume SMT production lines with minimal component replenishment interruptions.

Frequently Asked Questions
What capacitance, voltage rating, and tolerance does the EEE-FK0J470R offer for power supply filtering?
The Panasonic EEE-FK0J470R provides 47µF capacitance rated at 6.3V with a ±20% tolerance. These parameters make it well-suited for bulk decoupling and output filtering on 3.3V and 5V power rails in DC-DC converters and LDO regulators, where the 47µF value helps smooth transient load currents and reduce output voltage ripple to acceptable levels.
For a portable wearable device design, how does the SMD package of EEE-FK0J470R save board space compared to through-hole alternatives?
The SMD package of the EEE-FK0J470R eliminates through-hole drilling, allowing the capacitor to be placed on the bottom side of a double-sided PCB and reducing the required board area footprint compared to radial through-hole electrolytic capacitors of the same 47µF value. This is particularly important in wearables and IoT devices where PCB dimensions may be constrained to under 20mm x 20mm, and every square millimeter of board area has a direct impact on product size.
When should a designer choose EEE-FK0J470R over a ceramic capacitor of the same capacitance for a 5V bus decoupling role?
The EEE-FK0J470R aluminum electrolytic is preferred when cost is a priority for bulk capacitance above 10µF on a 5V rail, since multi-layer ceramic capacitors (MLCCs) of 47µF at 6.3V in comparable SMD packages can cost 3 to 5 times more per unit at volume. However, if the design requires very low ESR below 10 mΩ or operation above 85°C, a polymer aluminum or MLCC alternative may be more appropriate, as standard electrolytic capacitors typically have higher ESR and a narrower operating temperature range of -40°C to +85°C.
