CANISTER DIODE HAVING IMPROVED ENVIRONMENT PROTECTIVE INSULATION AND ITS METHOD OF ASSEMBLY

摘要

A top hat or canister type diode is provided with improved insulation between its canister electrode and the oppositely poled electrical lead by the use of a hot melt adhesive material having a relatively high dielectric constant used to coat and electrically seal the insulator between the diode electrodes. By inserting a relatively rigid paper stiffener member, the hot melt material will be retained in the proper position with respect to the diode electrodes. The degree of improvement in the insulation between the canister and the oppositely poled electrical lead can be conveniently controlled by merely changing the diameter of the paper disc and the quantity of hot melt resin.
