Electrical
properties
|
| With negligible dependence of electrical
properties on temperature, voltage, frequency and
time. |
|
| With predictable change of properties with
temperature, voltage, frequency and time, this
dielectric is ferroelectric and offers higher capacitance
ranges than NPO |
|
| With high twist dielectric constant and greater
variation of properties with temperature and test
condition, very high capacitance per unit volume. |
|
|
Application
|
| Use in circuits need stable performance. Be
produced 100/200V high volt. |
|
| Use as blocking, coupling, by-passing
discriminating element. |
|
| Suited for by-passing and coupling application
such store power and memory circuit. High
cap-value with lower voltage. |

a 25% methanol solution of rosin and then into molten
solder of 235¡æ ¡À5¡æ for 2¡À0.5seconds,in both cases
the depth of dipping is up to about 2.5 to 3.0mm
from the root of lead. |
|
|
Resistance
to soldering
heat
|
| There shall be no evidence of damage or flash
over during the test and sign in focus. |
