Overview
A 600-piece ceramic capacitor assortment in a labelled plastic storage case — essentially every value you need for high-frequency bypassing, RC filters, oscillator timing, and signal-coupling work, from 10 pF picofarads up to 10 µF microfarads, all rated 50V. Ceramic caps are non-polarised, physically tiny, and have very low ESR, which makes them the right choice for digital decoupling next to microcontroller pins, RF filtering, and any application where the dielectric losses of an electrolytic would matter.
Each compartment of the included case is labelled with its capacitance, so you can find a 100 nF (0.1 µF) for decoupling or a 22 pF for a crystal oscillator without sorting through hundreds of identical-looking yellow lozenges. Multilayer construction (MLCC) and through-hole leads make these compatible with breadboards, perfboard, and conventional PCB pads.
This is the companion kit to the electrolytic-capacitor assortment — together they cover the full capacitance range from picofarads up through hundreds of microfarads, which is everything an Arduino, ESP, RF, audio, or analog signal-conditioning project needs.

Reading the Cap
Ceramic capacitors use a 3-digit code printed on the body:
| Marking | Capacitance |
| "103" | 10 × 10³ pF = 10 nF = 0.01 µF |
| "104" | 10 × 10&sup4; pF = 100 nF = 0.1 µF |
| "105" | 10 × 10&sup5; pF = 1 µF |
| "106" | 10 × 10&sup6; pF = 10 µF |
| "22" (no third digit) | 22 pF |
| "100" (with no multiplier code) | 10 pF (= 10 × 10&sup0;) |
| "472" | 47 × 10² pF = 4.7 nF |
The first two digits are the significant figures; the third is the power-of-10 multiplier. Read in picofarads, then divide by 1000 for nanofarads or 1,000,000 for microfarads.

| Coupling between op-amp stages | 0.1 µF |
| RF / WiFi module shielding | 1 nF + 100 pF in parallel |
| I2C bus snubber (slow rise time) | 10 pF on each line if needed |
| Local LED current ripple smoothing | 0.1 µF across the LED supply rail |
