FAE Expert Insights
"The JJC0E156 is my go-to recommendation for energy harvesting applications where battery replacement is impractical. The 500,000+ cycle life essentially means infinite operational life in most energy harvesting scenarios. I've deployed this supercapacitor in numerous wireless sensor networks where it stores energy from solar or vibration harvesters and provides burst power for data transmission. The 15F capacitance provides adequate storage for most IoT applications, and the low ESR ensures efficient charge transfer from the harvester. The -25°C temperature rating is important for outdoor applications. For designs requiring higher voltage, I recommend series configurations with active balancing circuits."

Frequently Asked Questions
How do I calculate backup time for supercapacitor-powered applications?
Backup time calculation for supercapacitors: t = C × (V_initial² - V_final²) / (2 × P), where t is backup time, C is capacitance, V_initial is starting voltage, V_final is minimum operating voltage, and P is power consumption. Example: JJC0E156 (15F) charged to 2.5V, powering a 0.1W load down to 1.8V: t = 15 × (2.5² - 1.8²) / (2 × 0.1) = 15 × (6.25 - 3.24) / 0.2 = 15 × 3.01 / 0.2 = 226 seconds (~3.8 minutes). For constant current loads: t = C × (V_initial - V_final) / I. Example: 10mA load: t = 15 × (2.5 - 1.8) / 0.01 = 15 × 0.7 / 0.01 = 1050 seconds (~17.5 minutes). Note: Include self-discharge current (~10-50μA) in calculations for long backup times.

What is the difference between EDLC supercapacitors and batteries?
EDLC supercapacitors and batteries have different energy storage mechanisms: Energy Density: Batteries store 100-300 Wh/kg (lithium-ion), EDLCs store 5-10 Wh/kg - batteries store 10-50x more energy per weight. Power Density: EDLCs deliver 10,000+ W/kg, batteries deliver 100-500 W/kg - EDLCs can charge/discharge 10-100x faster. Cycle Life: Batteries last 500-2000 cycles, EDLCs last 500,000+ cycles - EDLCs last 100-1000x longer. Efficiency: Batteries are 70-90% efficient, EDLCs are 95-98% efficient. Temperature: Batteries work -20°C to +60°C, EDLCs work -40°C to +70°C. Self-Discharge: Batteries lose 1-5% per month, EDLCs lose 10-40% per day. Selection guidelines: Use batteries for long-term energy storage and applications requiring high energy density. Use EDLCs for high-power pulses, frequent cycling, and applications where maintenance-free operation is critical. Many designs use both - battery for bulk storage, EDLC for peak power.
Use EDLCs for high-power, high-cycle applications; use batteries for high-energy, long-term storage.
