World’s smallest LED blinky
https://www.electronics-lab.com/worlds-smallest-led-blinky/
Mike Harrison has build what he claims the “world’s smallest” led blinky. Likely it is based on the CPH3225A supercapacitor giving the blinky a footprint of 3.2 x 2.5 mm. With that in hand he added a PIC 10f322 microcontroller in a SOT23 package, an 0603 smoothing capacitor, and an SMD LED. The tiny […]
Back-up power manager can support two supercapacitors
https://www.electronics-lab.com/back-up-power-manager-can-support-two-supercapacitors/
A complete supercapacitor back-up power management system for 2.9 to 5.5V supply rails is available from Analog Devices. The LTC4041 uses an on-chip bi-directional synchronous converter to provide high efficiency step-down supercapacitor charging. There is also high current, high efficiency boost back-up power. When external power is available, the device operates as a step-down battery […]

Peggy Lee @ newelectronics.co.uk discuss about MURATA’s ultra thin supercapacitor. The DMH series from Murata is said to be the lowest profile supercapacitor. The product is designed for peak power assist duties in wearable applications and various other devices. Measuring 20 x 20mm, the 0.4mm thick DMHA14R5V353M4ATA0 supercapacitor is claimed to be suitable for use […]
Supercapacitors Surpassing Conventional Batteries
https://www.electronics-lab.com/supercapacitors-surpassing-conventional-batteries/
Researchers at the University of Central Florida have been looking for alternatives for lithium rechargeable batteries which are largely used in every device. Using two-dimensional (2D) transition-metal dichalcogenides (TMDs) capacitive materials, they are building a new supercapacitor that overcomes the performance of conventional lithium battery and replaces its efficiently. Transition metal dichalcogenide monolayers (TMDs) are […]
These tiny batteries can be charged in seconds and last for a week
