60% smaller footprint and 70% smaller volume than
our conventional 1608(0603)-sized TCM series capacitors.
2) High capacitance : 1.0F to 4.7F ( 15F Under development )
Ideal for coupling and noise reduction in audio circuits
3) High productivity, high reliability
Featuring the popular underside electrode configuration
4) Environmentally friendly halogen-free package
