For over 40 years Coin Cell super capacitors have served the Electronics market well for the purpose of Back up for RTCs especially. The technology is now very old and manufacturers are no longer committing to maintenance of production, lead times are extending and some manufacturers are withdrawing production, so what is there to replace this reliable product?
Other manufacturers of smaller capacitance Super Capacitors have not been successful filling this void but EDLC's maybe the best solution
Farnell are now stocking the VINATech 2846641 WEC6r0 504QG-I (0.5F) and 2846642 WEC6r0 155QG-I (1.5Farad) RoHS , WEEE & REACH compliant products.
This modern technology covers the required voltages and capacitance ranges of Coin cells but offers huge benefits of longer life , greatly improved ESR , higher current ratings , wider temperature range whilst being in a similar size to its predecessor . The EDLC version offers VINATech’s leading Anti Wetting technology and is perfect for IoT communication pulse demands.
