Zimo SuperCap68 Stay-Alive super capacitor
Super capacitors offer huge electrical storage in small packages. Zimo's SuperCap68 is rated at a whopping 6800uF/15V, but measuring only 20x15.5x5.8mm in a convenient flat block shape. Ideal for use with the MX645/MX644 sound decoders and any other Zimo decoder that has built-in connectors for 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 SPEIKCOMP pack.
Suitable for DCC systems where the track voltage is 15V or less (most, but probably not large scale).
