What are the key features of EEEFK2A470AQ?
- 47 µF, 100 V rating supporting high-voltage bulk energy storage in industrial power supply designs
- Low leakage current of 0.047 mA maintaining charge retention efficiency in voltage hold circuits
- 12.5 mm × 13.5 mm aluminum can package providing thermal mass for stable operation in harsh environments
- RoHS and REACH compliant wet electrolytic construction suitable for long-lifetime industrial applications
What is EEEFK2A470AQ used for?
EEEFK2A470AQ is used as a bulk filter capacitor on high-voltage DC bus rails in industrial power supplies and motor drives where 47 µF at 100 V provides energy storage to ride through transient load steps. The low leakage current makes it suitable for energy hold circuits in uninterruptible power supplies (UPS) and backup power modules where stored charge must be retained during standby periods. Its robust aluminum wet construction is also applicable in power factor correction (PFC) stages and industrial inverter DC link filtering.

Frequently Asked Questions
What voltage and capacitance does the EEEFK2A470AQ offer for high-voltage power supply filtering?
The EEEFK2A470AQ provides 47 µF capacitance at a 100 V working voltage, placing it in the class of high-voltage bulk filter capacitors suitable for DC bus rails in industrial equipment operating from rectified 60 V to 85 V AC lines. This combination stores approximately 235 µJ of energy, providing hold-up capability for transient load steps of several amps over microsecond time windows in switch-mode power supply output stages.
How does the 0.047 mA leakage current of EEEFK2A470AQ affect circuit design in energy-hold applications?
A leakage current of 0.047 mA through the 47 µF capacitor means that in a 100 V hold circuit with no active discharge, the capacitor will self-discharge at approximately 3.76 V per second, calculated as I/C = 0.047 mA / 47 µF. For UPS and backup power designs requiring the capacitor to hold charge for several seconds, this leakage rate is acceptable, but for hold times exceeding 30 seconds, additional charge refresh circuitry or parallel capacitor banks may be required.
What PCB mounting and can dimensions must designers account for when using EEEFK2A470AQ in a board layout?
EEEFK2A470AQ uses a through-hole radial lead configuration with a 12.5 mm diameter can and 13.5 mm body height, requiring a PCB pad hole pattern sized for the standard FK series lead spacing of 5 mm. Designers must reserve a component keep-out zone of at least 13 mm × 15 mm including lead bend radius, and ensure 15 mm minimum clearance above the board surface for the capacitor body to allow conformal coating and adequate airflow in forced-convection cooling designs.
When should an engineer choose EEEFK2A470AQ over a film capacitor for 100 V rail filtering?
EEEFK2A470AQ with 47 µF at 100 V is the better choice over a film capacitor when the application requires bulk energy storage at relatively low frequency ripple (below 100 kHz) and cost-optimized solution size is prioritized, since a 47 µF, 100 V film capacitor would be 5 to 10 times larger and more expensive. Film capacitors are preferred when high-frequency ripple above 100 kHz or operating temperatures above 105°C are required, scenarios where aluminum electrolytic ESR becomes too high or lifetime degrades.
