Silicon Nitride Ceramic Heat Component made of silicon nitride are normally rectangular in shape. Alloy wire is wrapped in dense silicon nitride ceramic body, where silicon nitride plays the role of heat transfer medium, dielectric medium as well as protect cover of alloy wire. With excellent thermal conductivity, insulation performance and comprehensive mechanical properties, the thickness of Torbos silicon nitride ceramic heat component is only 4 mm. The unmatched thermal expansion coefficient makes the scale crack and fall off on their own from the ceramic heater surface. The maximum safe heat load can reach 70 W/cm2, this makes this ceramic heat component only 1/3 in size compared with traditional electric heater.  This extraordinary heat component is your reliable choice for you heat solution and will provide you open ended design possibility.

Although the leakage current is negligible, we still highly recommend you set the ground connection

This 10 mA is the safe limitation stated in IEC60335 (GB4706.1-2005)

The maximum surface heat load of a ceramic heat component depends on the property

medium haba, mekanisme pemindahan haba dan suhu kerja (WT). Contohnya

beban haba permukaan boleh menjadi 70 W cm2 apabila memanaskan air pada WT di bawah 80 oC
