SuperCap Energy Storage Unit20x15.5x5.8mm (17000uF)Suitable as stay-alive for Zimo decoders with 16V energy storage connections(MX645, MX631 etc.)Or via SACC16 kit for other decoders with +VE and GND connections.

Super capacitors offer huge electrical storage in small packages. YouChoos' SuperCap17000uF is rated at a whopping 17000uF/15V, but measuring only 20x15.5x5.8mm in a convenient flat block shape. Ideal for use with the MX645 sound decoders and any other Zimo decoder that has built-in connectors for a 16V energy storage. It can also be used with other decoders, such as the MX648, but you need to place it into a circuit with a SACC16 pack.

Suitable for DCC systems where the track voltage is 15V or less (most, but probably not large scale).

You can expect between 1 and 5 seconds backup time from this capacitor, depending upon the model and what it is doing at the time of power loss.
