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