TANCERAM CHIP CAPACITORS
TANCERAM chip capacitors can replace tantalum capacitors
in many applications and offer several key advantages over
traditional tantalums. Because Tanceram capacitors exhibit
extremely low ESR, equivalent circuit performance can often
be achieved using considerably lower capacitance values.
Low DC leakage reduces current drain, extending the battery
life of portable products. Tancerams high DC breakdown
voltage ratings offer improved reliability and eliminate large
voltage de-rating common when designing with tantalums.
ADVANTAGES
Low ESR Low DC Leakage
Higher Surge Voltage Non-polarized Devices
Reduced CHIP Size Improved Reliability
Higher Insulation Resistance Higher Ripple Current
APPLICATIONS
