Transistor Parts Power transistors and diodes need an insulation to prevent excessive heat reducing their performance, Precision punched mica washers help the transistor to be insulated from the chassis and to dissipate the heat away from the transistor and other semi-conductors.	Mica Washers These are mica discs with a round opening in the centre, which can be   bonded by shellac or epoxy into considerable lengths. Maximum use is in railways.
Mica for Liquid Level Indicators Mica being unaffected by high temperature and high pressure, is an ideal optical medium for checking the measurements in boilers for liquid level and pressure of steam.	Heating Elements Due to micas electrical insulation, it is used in irons, toasters and kettles for heating elements. In all these applications, the electrical wire is wound around the mica.
Cut Mica Discs Die cut or lathe cut round discs are used in liquid level indicators, breathing apparatus, communication devices, fuses, etc.	Window Mica Owing to thermal insulation and transparency, it is used as a see-through medium for kerosene stoves, petromax lamps, furnaces, etc.
