G'day,

Summary: Are all ceramic capacitors naturally "low leakage?"

A friend is building a battery powered remote control and has realised
that low leakage (< 0.5uA) capacitors in the circuit will significantly
increase battery life given that the main chip will enter a low power
sleep mode.

His design uses 10uF and 0.1uF capacitors for regulator stabilisation
and supply filtering throughout the board.  He has found low leakage
variants of the 10uF size in the Farnell cattledog, but not for the
0.1uF ceramics.  Does he need to look for them or do ceramics have a low
leakage anyway?
