Pamene anazindikira mwa mtundu 'kala' ikusonyeza wa resistors

Resistor - ndi chinthu wambiri, anapatsa dera pakompyuta. Iwo akhoza kulikonse, kuchokera losavuta kwa makina ochapira ndi kompyuta ano. Kusonyeza katundu wawo mitundu iwiri ya masanjidwe ntchito: choyamba - njira mtundu 'kala' ikusonyeza ntchito kwa mphete resistor thupi akuda, wachiwiri - alphanumeric.

Nthawi resistors ndi capacitors ndi lalikulu kukula kukaniza awo mwadzina (mphamvu) oyambitsa ntchito achidule muyezo zoti mayunitsi, ndi lotsatira - Nkosatheka kupatuka pa mtengo mwadzina anati, mwachitsanzo: 1.5% 10 ohms, 33 ohms 20%. mfundo izi encode ndi resistor mtundu code. Kubisa zipembedzo ka mankhwala tichipeza akonzedwa wapadera wa anthu otchulidwa alphanumeric. Koma nthawi yomweyo lero konsekonse ntchito malamulo mnemonic, amene utoto mphete amapanga resistors mitundu yosiyanasiyana. Malinga ndi dongosolo limenelo, ohm kukana ndiyotengera ndi kalata (E), 1000 ohm - ngati (K) megohms - ndi (M). Kukhoza mwadzina la 100-910 ohm resistors kuimira kiloomah mu tuzigawo twa, ndi osiyanasiyana 100000-910000 - megohms. Mu nkhani ya mwadzina kukana inteja lettering aikidwa pambuyo manambala a - ZZE (33 ohms), 1 M (1 M). Kujambulitsa kachigawo decimal kakang'ono kuposa umodzi amaika zizindikiro alifabeti pamaso chiwerengero, mwachitsanzo, M47 (470 ohms). Ndipo mu nkhani ya inteja decimal, kalata zinalembedwa pambuyo koma ndi: 1E5 (1.5 ohms), 1M5 (1.5 megohms). Zopezeka kulolerana chizindikiro kufufuza kukana chinaperekedwa: 5%, 10%, 15%. Mtundu wolemba pulogalamu resistor akhoza kuphatikiza mitundu onse kulemba.

mtundu 'kala' ikusonyeza

Amakhala mu tagging chipolopolo kunja kwa chipangizo kudzera 3 kapena zambiri concentric n'kupanga wachikuda. Njira iliyonse chifukwa kupenta ali ndi zina mtengo n'zosangalatsa kumva, disclosing katundu wa resistor lapansi. Kawirikawiri, Mzere otsiriza kuzichita kuchuluka kwa kulolerana ananena za mankhwala ndi Mzere woyamba wa nkhani zokhudza mankhwala. Mwachitsanzo, olemba ndi 4 mikwingwirima encode woyamba awiri chidebe kukula (Ohm), ndi chachitatu ndi chinthu cha mfundo anati. Mitundu yosiyanasiyana resistors akhoza decrypted ngati mankhwala ali pabwino kuti gulu lonse ndi kutsatira iye mphete onse anali pafupi dzanja lamanzere. Ndiye muyenera kugwiritsa ntchito poyerekezera tchati kuthandiza kumveketsa phindu kusiyana popemphera.

Mitundu yosiyanasiyana resistors osati kuitanitsa masamba onse bwino lomwe. mfundo ndi yakuti zopangidwa zoweta ali chizindikiro chake umagwiritsidwa, ndi achilendo - wina. Anthu ena opanga ndi chimasintha mfundo ndi kulenga anu mtundu chiwembu. kulemba zachilendo ntchito kusiyanitsa katundu amene amapangidwa malingana ndi zofuna MIL kuti zimasiyana annotations zolinga mafakitale ndi zoweta, apakamwa moto kukana katundu, etc. Mwachitsanzo kampani "Philips" akusonyeza ubwino resistors monga analandira kulikonse, mwachitsanzo manambala zikusonyeza kanjedza mu ohms, ndi wotsiriza - ichi ndi multiplier. Malinga ndi lolondola ananena za resistor alandire mu mawonekedwe a zilembo 3-4. Kusiyana kwa ochiritsira 'kala' ikusonyeza bodza mu zamalankhulidwe katundu 7, 8 ndi 9, manambala lomaliza.
