8 / 84 page Effects of Mechanical Stress – High “K” dielectric ceramic capacitors exhibit some low level piezoelectric reactions under mechanical stress. As a general statement, the piezoelectric output is higher, the higher the dielectric constant of the ceramic. It is desirable to investigate this effect before using high “K” dielectrics as coupling capacitors in extremely low level applications. Reliability – Historically ceramic capacitors have been one of the most reliable types of capacitors in use today. The approximate formula for the reliability of a ceramic capaci- tor is: L o = V t X T t Y L t V o T o where Lo = operating life Tt = test temperature and L t = test life To = operating temperature in °C V t = test voltage Vo = operating voltage X,Y = see text Historically for ceramic capacitors exponent X has been con- sidered as 3. The exponent Y for temperature effects typically tends to run about 8. 7 The Capacitor Figure 8 .001mF .01mF .1mF .33mF 1 10 100 1000 Log Frequency, MHz 10.00 1.00 0.10 0.01 1 10 100 200 Log Frequency, MHz 10.0 1.0 0.1 1 10 100 1000 Log Frequency, MHz 10.0 1.0 0.1 100.0 .500" .250" .062" 0" 1 10 100 1000 10,000 100,000 Hours +1.5 0 -1.5 -3.0 -4.5 -6.0 -7.5 Characteristic Max.
