Ceramic capacitors tuaj yeem faib ua ntau txoj hauv kev, suav nrog cov khoom siv dielectric, qhov kub thiab txias coefficient, thiab kev tsim kho. Nov yog qee txoj hauv kev los faib cov ceramic capacitors:
1. Dielectric Khoom - Ceramic capacitors tuaj yeem ua nrog ntau hom khoom siv ceramic, xws li:
- Chav Kawm 1 ceramics: Cov no suav nrog C0G, NP0, thiab UHF ceramics, uas muaj cov dielectric siab tas li thiab muaj kev ruaj khov nyob rau hauv qhov kub thiab txias. Lawv feem ntau yog siv nyob rau hauv high-frequency daim ntaub ntawv.
- Chav Kawm 2 ceramics: Cov no suav nrog X7R, Y5V, thiab Z5U ceramics, uas muaj qhov qis dielectric tas li thiab qhov kub thiab txias coefficient ntawm capacitance. Lawv feem ntau yog siv rau hauv cov ntawv thov tsawg zaus.
2. Temperature Coefficient - Ceramic capacitors tuaj yeem raug cais los ntawm lawv qhov kub coefficient ntawm capacitance (TCC). Lub TCC ntsuas qhov capacitance ntawm lub capacitor hloov nrog qhov kub thiab txias. Feem ntau TCC kev ntsuam xyuas yog:
- Chav Kawm 1 ceramics muaj TCC ntawm 0 ± 30 ppm / ° C.
- Chav Kawm 2 ceramics muaj TCC ntawm ± 15% txog ± 22% dhau qhov ntsuas kub tshwj xeeb.
3. Kev tsim kho - Ceramic capacitors tuaj yeem raug cais los ntawm lawv txoj kev tsim kho, xws li:
- Multilayer ceramic capacitors (MLCCs): Cov no yog tsim los ntawm stacking alternating txheej ntawm ceramic khoom thiab hlau electrodes. Lawv yog cov feem ntau hom ceramic capacitor thiab muaj lub siab capacitance ceev.
- Ib txheej txheej ceramic capacitors: Cov no yog tsim los ntawm txheej txheej ceramic nrog hlau electrodes. Lawv muaj lub peev xwm qis dua li MLCCs tab sis muaj qis inductance.
- Feedthrough capacitors: Cov no yog tsim los muab EMI lim thiab feem ntau yog siv rau hauv daim ntawv thov fais fab.
Zuag qhia tag nrho, kev faib tawm ntawm ceramic capacitors yog qhov tseem ceeb kom nkag siab vim tias ntau hom capacitors muaj cov kev siv sib txawv thiab cov yam ntxwv ua haujlwm.
