Sabis na Masana'antar Lantarki ta Tasha ɗaya, yana taimaka muku samun samfuran lantarki cikin sauƙi daga PCB & PCBA

Common circuit Board GND da harsashi GND indirect daya resistor da capacitor daya, me yasa?

asd (1)

 

An yi harsashi ne da ƙarfe, tare da rami mai dunƙulewa a tsakiya, wanda ke haɗa da ƙasa. Anan, ta hanyar resistor 1M da capacitor 33 1nF a layi daya, hade da filin da'ira, menene amfanin wannan?

Idan harsashi ba shi da kwanciyar hankali ko yana da wutar lantarki, idan an haɗa shi kai tsaye zuwa allon kewayawa, zai karya guntu allon kewayawa, ƙara capacitors, kuma zaku iya ware ƙananan mita da babban ƙarfin lantarki, wutar lantarki da sauran su don kare kariya. allon kewayawa. Za a haɗa shi kai tsaye tare da tsangwama mai saurin kewayawa da makamantansu da harsashi ta capacitor, wanda ke yin aikin raba sadarwar kai tsaye.

Don haka me yasa ƙara resistor 1M? Wannan shi ne saboda, idan babu irin wannan juriya, lokacin da akwai wutar lantarki a tsaye a cikin allon kewayawa, 0.1uF capacitor da ke da alaƙa da ƙasa yana datsewa daga haɗin da harsashi ƙasa, wato, dakatarwa. Wadannan cajin sun taru zuwa wani matsayi, za a sami matsaloli, dole ne a haɗa su da ƙasa, don haka ana amfani da juriya a nan don fitarwa.

1M juriya yana da girma sosai, idan akwai wutar lantarki mai tsayi a waje, babban ƙarfin lantarki da makamantansu, kuma yana iya rage ƙarfin halin yanzu yadda ya kamata, kuma ba zai haifar da lalacewa ga guntu a cikin kewaye ba.
