we have a solution against THINKING gdt and mov . we have been bring down your failure ratio of your product which occurred by the high surge current or voltage . the THINKING providing the solution for surge by their gas discharge tub and metal oxide varistor , but , as people are not aware of advance technology - beyond the such type of components . " we offer a most advance technology compare with THINKING METAL OXIDE VARISTOR and GAS DISCHARGE TUBE solution. which is much more faster , very low clamping voltage , low capacitance , no thermal runaway , high insulation resistance , very fast response in nano sec. , long life and very small package like FILM CAPACITOR. product called PLM (power line module) the same can be with EPCOS MOV and GDT also. our"PLM" can used internally as well as externally also. these PLM'S are design for those people who want their product to be very superior and on top in class .
