Key Features
- 47 µF capacitance at 25 V DC rating with low 1.36 Ω ESR for efficient bulk decoupling in switching power supplies
- Surface-mount cylindrical package (5.8 mm height) enables automated PCB assembly and a smaller board footprint than radial through-hole alternatives
- RoHS and REACH compliant construction with aluminum wet electrolytic dielectric rated for long operational lifetime
Applications
The EEEFK1E470AP is suited for output bulk decoupling and energy storage in DC-DC converters and LDO power stages operating up to 25 V, where a 47 µF SMD capacitor reduces output voltage ripple below design margins. It is also used in audio amplifier power rails and motor driver supply lines to absorb transient load currents. The SMD format makes it straightforward to integrate into compact consumer electronics, industrial sensors, and telecommunications equipment.

Frequently Asked Questions
What is the rated capacitance and voltage of the EEEFK1E470AP and how do these values suit typical power supply designs?
The EEEFK1E470AP provides 47 µF at a 25 V DC working voltage with ±20% tolerance. These values cover the bulk output decoupling requirement of most 5 V to 12 V switching regulator stages, where 47 µF is a standard reservoir value for load transient suppression and output ripple reduction below 50 mV.
How does the 1.36 Ω ESR of the EEEFK1E470AP compare to polymer capacitors and when is it the better procurement choice?
At 1.36 Ω, the EEEFK1E470AP has higher ESR than polymer aluminum capacitors (typically 0.01–0.1 Ω), but its 25 V, 47 µF electrolytic construction costs significantly less per unit at volume. It is the preferred choice when ripple current requirements are below 50 mA RMS and cost targets limit the use of low-ESR polymer alternatives.
What is the leakage current specification for the EEEFK1E470AP and why does it matter in battery-powered circuits?
The EEEFK1E470AP specifies a maximum DC leakage current of 0.0118 mA (11.8 µA) at rated voltage and room temperature. In a battery-powered design with a 1000 mAh cell, this leakage alone contributes less than 0.1% continuous self-discharge per hour, making it acceptable for most sleep-mode applications that periodically charge the cap from a 25 V rail.
For a compact DC-DC converter PCB, what board height does the EEEFK1E470AP occupy and how does that affect component clearance?
The EEEFK1E470AP stands 5.8 mm tall on the PCB, requiring at least 6 mm of component clearance above the board surface. This height is compatible with standard 7 mm or 8 mm PCB-to-enclosure clearances found in power converter modules, and shorter than the 8–10 mm typical of equivalent radial through-hole 47 µF capacitors.
