LT240 thermal conductive ceramic has a high thermal conductivity : 24w/m.k, it is of simple construction and small volume, but it can
resist acid and alkali corrosio, work in high temperature and pressure and of stable performance for a long time.0.635mm, 1.0mm, 2.0mm,
3.0mm, 4.0mm can be offered for TO-220, TO-247, TO-264, TO-3P sizes,customized size is available, ROHS is compliant.
Typical applications:
IC, MOS, transistor, schottky, IGBT, high density switch
power supply, HF communications equipment and
brazing machine.
