Berikut panduan umum untuk menentukan nilai kapasitor sesuai fungsinya dalam rangkaian elektronik:

Table

Fungsi KapasitorRumus/Aturan PemilihanContoh Nilai Standar (E-series)
Decoupling (dekupel)Pilih 0,01 µF–0,1 µF dekat tiap pin supply IC untuk meredam noise frekuensi tinggi.0,01 µF, 0,1 µF (0603, 0805)
Bulk-/Filter-SupplyGunakan 1 µF–100 µF pada rail daya untuk stabilisasi jangka panjang, tergantung arus beban dan regulator.1 µF, 4,7 µF, 10 µF, 22 µF
High-pass (kopling sinyal)Fc = 1/(2π·R_load·C) → C = 1/(2π·R·Fc). Pilih C sedemikian rupa agar Fc jauh di bawah frekuensi sinyal terendah.10 nF, 47 nF, 100 nF
Low-pass (RC filter)Fc = 1/(2π·R_source·C) → C = 1/(2π·R·Fc). Tentukan Fc sesuai noise atau bandwidth yang diinginkan.1 nF, 4,7 nF, 10 nF
Timing/oscillatorSesuai datasheet IC: C = 1/(f·K) (nilai K tergantung rangkaian). Ikuti rekomendasi pabrikan agar stabil.Sesuai datasheet
Snubber (RC dioda/flyback)R ~ 1–100 Ω, C ~ 100 pF–1 nF untuk meredam spike pada beban induktif.220 pF, 470 pF + R 10 Ω
ADC input samplingC_input ~ 1/(2π·R_source·Fs) agar settling time tercukupi sebelum konversi.100 pF, 220 pF
  1. Tentukan tujuan fungsi (dekupel, filter, timing, kopling, dsb.).
  2. Pilih rumus cutoff jika ada (filter/high-pass/low-pass).
  3. Perkirakan impedansi referensi (R_load atau R_source).
  4. Hitung C dengan C=12πR FcC = \frac{1}{2\pi R \, F_c} jika relevan.
  5. Pilih nilai kapasitor terdekat di E6/E12/E24 (misal 47 nF bukan 50 nF).
  6. Perhatikan tegangan kerja (V_rating ≥ 1,5× tegangan maksimum).
Contoh sederhana: untuk kopling audio antara tahap dengan R_load = 10 kΩ dan Fc = 20 Hz:
C = 1/(2π·10 000·20) ≈ 0,8 µF → pakai 1 µF (E6/E12).
Semoga membantu!
