Polyester capacitor parameter kev txheeb xyuas thiab daim ntawv lo

Parameter identification

Txawv teb chaws capacitor withstand voltage qhov tseem ceeb yog feem ntau qhia nyob rau hauv cov tsiaj ntawv, thiab cov code thiab cardinality yog:

A: 1.0; B: 1.25; C: 1.6; D: 2.0; E: 2.5; F: 3.15; G4.0;

H: 5.0; J: 6.3; K: 8.0; Z: 9.0;

Tus lej ua ntej tsab ntawv qhia tias lub zog ntawm 10, xws li 2A, uas yog 102 * 1.0=100V, 2C yog 102 * 1.6=160V, thiab lwm yam.

Tsab ntawv tom qab qhov hluav taws xob tiv taus qhia tias muaj peev xwm hauv pF.

Piv txwv li, 823 qhia tias muaj peev xwm ntawm 82 * 10^3=82000Pf, 224 qhia 22*104=220000pf=0.22μF; tsab ntawv kawg qhia qhov tseeb, xws li J qhia lub peev xwm kam rau siab ntawm ± 5% thiab lwm yam.

Cov piv txwv ntawm kev txheeb xyuas qhov muaj peev xwm: 2A823J yog 82000Pf ± 5%, withstand voltage 100V [1].

Parameter labeling method

Txoj kev ncaj ncaj

Lub ntsiab tsis muaj peev xwm ntawm lub capacitor (nominal peev, ntsuas qhov ntsuas hluav taws xob, thiab qhov sib txawv ntawm qhov tso cai) yog cim ncaj qha rau ntawm lub capacitor, xws li {{0}}.0047μf / 275V, 0.0047μf yog lub peev xwm, sib npaug rau 4700Pf, 275V yuav tsum tiv taus voltage (tsis nyiam series).

Cov ntawv sau

Cov tsis tseem ceeb ntawm lub capacitor yog sau los ntawm tus lej lossis sib xyaw ntawm cov ntawv thiab cov lej.

1. Digital notation Feem ntau, lub peev xwm ntawm lub capacitor yog sawv cev los ntawm tus lej 3-tus lej. Thawj ob tus lej yog tus lej rms, thiab tus lej thib peb yog tus lej sib npaug (piv txwv li, pes tsawg tus lej muaj tom qab tus nqi rms). Piv txwv li, 104 qhia tias tus nqi zoo yog 10, ua raws li plaub xoom, uas yog, 100000 Pf=0.1 μf.

2. Kev sib xyaw ua ke ntawm cov tsiaj ntawv thiab cov lej Siv 2-4 tus lej los sawv cev tus nqi zoo, thiab siv P, n, M, μ, G, m thiab lwm yam tsiaj ntawv los qhia qhov loj tom qab tus lej tseem ceeb. Imported capacitors tsis siv tus lej lej thaum cim qhov tseem ceeb, tab sis sau tus lej ua ntej tsab ntawv thiab tus lej lej tom qab tsab ntawv. Piv txwv li, 4P7 sawv cev rau 4.7Pf, thiab 3m3 sawv cev rau 3300μf (3.3mf) lossis lwm yam.
