1900 Italian L. Lombardo Duab Ming, ceramic dielectric capacitors. Nws tau pom nyob rau hauv lub 1930s lig kom ntxiv titanate ceramics tuaj yeem loj hlob tshaj tawm dielectric tas mus li, thiab yog li tsim ib lub cheaper ceramic dielectric capacitors.

Xyoo 1940 tom qab nws pom tias tus thawj xib fwb cov khoom siv yog ceramic capacitors BaTiO3 (barium titanate) muaj cov cuab yeej insulating tom qab pib lub ceramic capacitor hauv cov khoom siv hluav taws xob uas ob qho me me, thiab qhov tseeb ntawm cov tub rog. Thaum ceramic laminations capacitor nyob ib ncig ntawm 1960 pib tsim los ua khoom muag. Xyoo 1970, nrog kev nce qib ntawm hybrid IC, khoos phis tawj, thiab cov khoom siv hluav taws xob nqa hluav taws xob kuj tseem yuav loj hlob sai, thiab dhau los ua qhov tsis tseem ceeb hauv cov khoom siv hluav taws xob. Tag nrho cov xov tooj ntawm cov xaib (dielectric capacitor) li txog 70% ntawm cov lag luam capacitor.
