A 0.47 µF 50 V capacitor is an electronic component used to store and release small amounts of electrical energy, commonly found in filtering, decoupling, and timing circuits. It can be made in various types, including ceramic, electrolytic, tantalum, and film, each suited for different applications. Ceramic and film versions are non-polarized and ideal for AC signals or general-purpose use, while electrolytic and tantalum types are polarized and preferred in DC filtering or power supply smoothing. The “50 V” rating indicates the maximum voltage the capacitor can safely handle, and “0.47 µF” (or 470 nF) denotes its capacitance value, which determines how much charge it can store.
A 2.2 µF 50 V capacitor is designed to store 2.2 microfarads of electrical charge and operate safely up to 50 volts DC. These capacitors are commonly available in several types: polarized aluminum electrolytic for DC filtering and smoothing in power supplies; non‑polarized bipolar electrolytic versions for AC-coupled or bidirectional circuits; and polyester film capacitors for stable, non‑polarized applications where low loss and accuracy matter. Aluminum electrolytics offer compact capacitance in a small package but have moderate tolerance (±20%) and higher ESR, while bipolar electrolytics allow reversed polarity operation. Film capacitors, though larger, deliver tighter tolerance (±5–10%), low dissipation, and more stable behavior over temperature. Ideal uses include decoupling, bypass, timing, and energy storage in analog and digital circuits.
A 220 µF, 16 V aluminum electrolytic capacitor is a polarized component packaged in a cylindrical aluminum can (typically around 6.3 mm diameter × 11–12 mm height) with radial leads and an insulated sleeve (often black or dark-colored). Designed for power supply smoothing, decoupling, and buffering in low‑voltage DC circuits, these capacitors offer modest ESR, ±20% tolerance, and long-term reliability—typically rated for ~2,000 hours at 85 °C or 105 °C, depending on series.
A 22 µF 50 V aluminum electrolytic capacitor with a black-coated case is a polarized, through-hole component frequently used for power supply smoothing, decoupling, and charge storage applications. These compact radial capacitors—typically 5 mm in diameter and 11 mm tall—offer high capacitance in a small footprint, usually with ±20% tolerance. Designed for operating temperatures from –40 to +85 °C or up to +105 °C depending on the series, they often have an ESR around 7–8 Ω and a rated lifetime of ~2000 hours at 105 °C.

The 5-Channel Flame Sensor Module is a 5-channel flame detector module used to detect flame in a larger area (>120 degrees). Each sensor is arranged at 30 degrees. This module outputs an analog signal, which would be more precise, and also a digital signal which would be easier to use, you can adjust the digital output sensitivity by the onboard potentiometer. The 5 LED indicators are helpful in your debugging, the high-precision resistors also make this sensor more precise than other flame sensors.
