NOTE:
TAPING :Types LC2, LC4, LC5 & LC7 can be supplied in taped form.
NOTE:
Due to recent technological advances, the ceramic cases used may be
steatite ceramic/corderite ceramic/high alumina ceramic depending on the nature of
application. Hence the ceramic cases may be off-white/variations of brown and variations
of grey; colours which are inherent to these ceramic materials.
