NOTE:
TAPING :Type C-2A, C-4, C-5B and C-7B can be supplied in taped form..
Please refer to the Taping Specification.

NOTE:
Due to recent technological advances, the ceramic cases used may be steatite ceramic / corderite ceramic / high alumina ceramic depending on the nature of the application. Hence the ceramic cases may be off-white / variations of brown and variations of grey; colours which are inherent to these ceramic materials.
