Slide 3: 3 key points to remember
3 key points to remember 1. In general supercapacitors are an ideal buffer between a low power energy source and a load with high peak power 2. Supercapacitors enable 3 Volt coin cell batteries to be used where: ▪ a 3V coin cell battery alone could not work (e.g. Spire) or ▪ greatly extend battery r

Slide 7: When to use supercapacitors
When to use supercapacitors • Use supercapacitors when peak power exceeds the limits of the primary energy source ▪ Supercapacitors offer peak load support either as a power buffer or back-up energy reservoir ▪ While the source (battery or energy harvester) provides a constant, low power charge curr
Slide 8: Powering the IoT
Powering the IoT Many IoT applications use low power energy sources (small batteries & energy harvesters) ▪ Wearable electronics (activity/fitness bands, watches, healthcare) ▪ Portable electronics (smart cards, smart tags, key FOBs, handhelds) ▪ Connected electronics (smart home, wireless sensor ne
Slide 9: Supercapacitor options today
Supercapacitor options today If you are using a 3V coin cell battery then your supercapacitor options today are typically: 1. Use a low-drop out voltage regulator (LDO): ▪ Drops voltage from 3V to the maximum rated voltage of a single supercapacitor cell (typically 2.5V or 2.7V) ▪ Typical extra cost
