Resistor ụkpụrụ na ha designation

Resistor - ihe circuit, nke na-eje ozi iji belata ugbu a nime ya. Ọzọkwa, resistors na-eji iji belata nchegbu na ụfọdụ na nkewa n'ime ya akụrụngwa ugbu a. Ke eletriki na sekit na sekit resistors na-denoted site obere rectangles na a ụzọ nke mkpọ (onye na abụọ n'akụkụ dị). Abroad resistors na-anọchi anya a gbajiri akara.

Resistors bụ atọ isi parameters:

1. Standard eguzogide (resistor ụkpụrụ).
2. Ndidi.
3. Power dissipation.

Resistor ụkpụrụ - uru nke ha elu ọnụ na-eguzogide, ya bụ, uru kpọmkwem site na emeputa. Elu ọnụ na-eguzogide tụrụ na ohms. Resistors na-eji ihe fọrọ nke nta niile ọrụ, na-enwe a nta eletriki na ngwaọrụ. Nke a na-eduga ná nnukwu nso nke na-eguzogide ụkpụrụ. Otú ọ dị, e nwere resistor ụkpụrụ, nke bụ eluigwe na ala.

Echepụta resistor na a ụfọdụ kpọmkwem elu ọnụ uru bụ nnọọ ike, ya mere, iji nke a bara uru dị ka a na ndidi. Ka ihe atụ, ọ bụrụ na a kpọmkwem elu ọnụ na-eguzogide hà 10 ohms, N'ezie ọ ga-abụ ihe 10.1 9,98- ohms. Nke a na-akpọ ekwe omume njehie tolerances na tụrụ ka a pasent.

Power dissipation - otu n'ime ndị kasị mkpa ihe na-ekpebi resistor. Kọwaa pụtara nyere uru. A resistor site na nke ihe ọkụ ugbu a na-nọgidere na-ewe iwe. Heating na-adabere na nke ugbu a ike. Onye ọ bụla resistor nwere ụfọdụ okpomọkụ ịgba n'ofè nke ọ overheats na anyụ anyụ. Dissipation - bara uru nke ike nke electric ugbu a, agaghi asu resistor ga-akpọ. Dị ka ụkpụrụ nke resistors, ike dissipation - bụ a mgbe nile maka nke ọ bụla n'ime ha. Ọ na-egosi site na emeputa. On eletriki na sekit na sekit agamevu ike nke resistor ga-kpọmkwem. N'ihi ya designation eji kpọrọ ihe, kwụ na kwụ ọtọ. Site image na resistor icon edoghi ndị pụrụ iche n'ịgwa na-anọchi dị iche iche ike ụkpụrụ. Ahụkarị ụkpụrụ ke obere atụmatụ mbio n'etiti 1/8 watt na ise watts. Power dissipation maka ihe ọ bụla resistor nwere ike gbakọọ si Ohm iwu maka subcircuit. Iji kọwaa ya, mkpa ka ị mara na nke ugbu a na sekit na elu ọnụ uru nke resistor.

All ratings bụ etozu eguzogide. Nke ahụ bụ, na e nwere ụfọdụ ọkọlọtọ resistor ụkpụrụ. Ndị a ụkpụrụ, n'aka nke ya, na-grouped na ahịrị nke ihu ụkpụrụ nke resistors. N'ihi na ndị dị otú ahụ usoro DC guest 6: E6, E12, E24, E48, E96, E192.

N'ihi na ugbu a variables na-eji nanị mgbe ụfọdụ kwubara E6 na E3. The nọmba aha nke e nyere ahịrị na-anọchi anya na ọnụ ọgụgụ nke kwere omume ratings na usoro isiokwu a. Dị ka ihe atụ, a ọnụ ọgụgụ nke iche E6 agụnye nanị kwe omume na-esonụ ndị na-eguzogide: 1.0; 1.5; 2.2; 3.3; 4.7; 6.8.
