Abstract

본 발명은 박막형 칩 저항기의 퓨즈형 안정장치에 관한 것으로 그 기술적인 구성은 세라믹 기판(1) 상에 양측으로 은 도금에 의한 1차전극(5)이 형성되고 그 사이에 저항체가 인쇄되고, 상기 1차전극(5) 및 저항체(2) 사이에 얇은 금속막으로 이루어진 퓨즈형 안전장치(3)가 착설되어 그 상측으로 보호막(9)이 형성되며, 1차전극(5) 상측으로 2차전극(6)이 마련되고, 그 상측으로 니켈(Ni)도금(7)층과, 최종적으로 땜납(Sn/Pb)도금(8)층이 형성되는 것이다.The present invention relates to a fuse type stabilizer of a thin film type chip resistor, the technical configuration of which is formed on both sides of the primary electrode (5) by the silver plating on the ceramic substrate (1) and a resistor printed therebetween, A fuse-type safety device 3 made of a thin metal film is installed between the primary electrode 5 and the resistor 2 to form a protective film 9 thereon, and the secondary electrode above the primary electrode 5. (6) is provided, and the nickel (Ni) plating 7 layer and the solder (Sn / Pb) plating 8 layer are formed on the upper side.

이에 따라서, 칩 저항기의 과전압 및 과전류 인가시 퓨즈형 안전장치의 단락으로 칩 저항기내의 회로가 차단토록 되어 칩 저항기의 파손이 방지되고, 이에 따라 회로 내의 전자 부품의 연속적인 파손 및 오염이 방지토록되어 제품의 수명이 향상됨은 물론, 간단한 구성으로 인하여 제작이 용이한 것이다.Accordingly, when the overvoltage and overcurrent of the chip resistor are applied, a short circuit of the fuse type safety device may cause the circuit in the chip resistor to be blocked, thereby preventing the chip resistor from being damaged, thereby preventing the continuous damage and contamination of electronic components in the circuit. Product life is improved, as well as easy to manufacture due to the simple configuration.
