Frequently Asked Questions
What is the capacitance and rated voltage of the EECS5R5H474, and how do these values compare to standard electrolytic capacitors?
The EECS5R5H474 provides 470,000 µF (0.47 F) capacitance at a 5.5 V rating. Standard aluminum electrolytic capacitors in a similar package typically reach only 4,700 µF to 10,000 µF, meaning the EECS5R5H474 offers 50 to 100 times more capacitance, enabling backup hold-up times of several seconds to minutes in low-power circuits drawing 1 mA to 10 mA.
How many charge and discharge cycles can the EECS5R5H474 sustain, and how does this affect long-term reliability?
Electric double-layer supercapacitors with activated carbon electrodes like the EECS5R5H474 typically sustain over 500,000 charge and discharge cycles with less than 20 percent capacitance degradation. This far exceeds lithium-ion batteries limited to 500 to 1000 cycles, making the EECS5R5H474 the preferred energy storage choice for systems requiring frequent cycling such as regenerative braking or industrial UPS modules.
In which real-time clock backup applications is the EECS5R5H474 a practical alternative to a coin cell battery?
The EECS5R5H474's 0.47 F at 5.5 V can supply a real-time clock drawing 1 µA to 5 µA for several hours to days after main power loss without requiring battery replacement or chemical disposal. For systems expecting power interruptions of less than 24 hours, this supercapacitor simplifies regulatory compliance by eliminating hazardous battery materials while providing the required 3 V to 5 V hold-up voltage across a 2 kΩ to 10 kΩ load.
What PCB mounting requirements must be considered when designing with the EECS5R5H474 through-hole package?
The EECS5R5H474 uses through-hole mounting with a 6.5 mm body height, requiring PCB drill holes sized to the lead diameter. Designers should allow a minimum 2 mm clearance radius around the component to prevent thermal stress during wave soldering at peak temperatures of 260°C, and should confirm footprint lead spacing matches the standard EECS series 5 mm pitch to avoid rework costs in production.
