    • PURPOSE: A protection element is provided to improve reliability by miniaturizing and thinning, with a fusible alloy fuse surely operated in response to the heating of a resistance heating element. CONSTITUTION: A protection element includes a ceramic chip body(12), a fusible alloy fuse element disposed on the surface thereof, a resistance heating element disposed in a through-hole, and leading-out leads(15-17) disposed on the back thereof. Since the heating element comprises a resistor having a predetermined resistance value, and is embedded and filled in the through-hole, heating of the resistor accurately and speedily operates the fusible alloy fuse element through the ceramic chip body having good heat conductivity.
    • 目的:提供一种保护元件,通过小型化和减薄来提高可靠性,通过电阻加热元件的加热,可熔合金保险丝可靠地运行。 构成:保护元件包括陶瓷芯片体(12),设置在其表面上的可熔合金熔丝元件,设置在通孔中的电阻加热元件和设置在背面的引出引线(15-17) 它们。 由于加热元件包括具有预定电阻值的电阻器,并且嵌入并填充在通孔中,所以电阻器的加热通过具有良好导热性的陶瓷芯片体精确地并且快速地操作熔断的合金熔丝元件。
