Ceramic capacitors inogona kuiswa nenzira dzakasiyana, kusanganisira ne dielectric zvinhu, tembiricha coefficient, uye nzira yekuvaka. Heano dzimwe nzira dzakajairwa dzekuisa ceramic capacitors:
1. Dielectric Material - Ceramic capacitors inogona kugadzirwa nemhando dzakasiyana dzeceramic zvinhu, senge:
- Kirasi 1 Ceramics: Izvi zvinosanganisira C0G, NP0, uye UHF ceramics, ine yakakwira dielectric inogara uye yakagadzikana zvakanyanya pane yakafara tembiricha. Iwo anowanzo shandiswa mune yakakwira-frequency application.
- Kirasi 2 ceramics: Izvi zvinosanganisira X7R, Y5V, uye Z5U ceramics, iyo ine yakaderera dielectric inogara uye yakakwirira tembiricha coefficient ye capacitance. Iwo anowanzo shandiswa mune yakaderera-frequency application.
2. Temperature Coefficient - Ceramic capacitors inogona kurongeka nehuwandu hwekushisa kwe capacitance (TCC). Iyo TCC inoyera kuti capacitance ye capacitor inoshanduka sei nekushisa. Iwo anonyanyozivikanwa TCC ratings ndeaya:
- Kirasi 1 ceramics ine TCC ye0 ± 30 ppm/°C.
- Kirasi 2 ceramics ine TCC ye ± 15% kusvika ± 22% pane yakatarwa tembiricha renji.
3. Kuvaka - Ceramic capacitors inogona kuiswa nenzira yavo yekuvaka, yakadai se:
- Multilayer ceramic capacitors (MLCCs): Izvi zvinogadzirwa nekuturika alternating layers eceramic material uye simbi electrodes. Ndidzo dzinowanzozivikanwa mhando dzeceramic capacitor uye dzine yakakwira capacitance density.
- Single-layer ceramic capacitors: Izvi zvinogadzirwa nekuputira ceramic disk nesimbi electrodes. Ivo vane yakaderera capacitance density pane MLCCs asi vane yakaderera inductance.
- Feedthrough capacitors: Aya akagadzirirwa kupa EMI kusefa uye anowanzo shandiswa mumagetsi ekupa maapplication.
Pakazara, kurongeka kweceramic capacitors kwakakosha kuti unzwisise nekuti akasiyana marudzi emacapacitor ane akasiyana maapplication uye maitiro ekuita.
