Good Quality MCH Disc Resistor Heater Ceramic Core Heating Element 5V 5W is produced by implementing unique ceramic lamination processes. MCH prints resistors on
alumina sheet, and it's laminated and sintered for one piece.Our ceramic heaters can operate in atmospheric and vacuum environment. MCH technology offers significant advantages over metal basic sheath heaters,while the latter has limitations in thermal performance and material compatibility.Compared with PTC, MCH is more energy saving, safer and higher efficient. Currently, MCH is widely used as innovative heater in machinery, medical, semiconductor, electronic & electrical industries,etc.
