Learn how to select 47uF 16V capacitors for your electronics projects. Understand types, tolerance, ESR, and sourcing them locally at Communica.
Learn which type-electrolytic, ceramic, or tantalum-best fits your project.
Compare specs like ESR, ripple current, and tolerance for your circuit's needs.
Explore popular 47uF 16V capacitor brands and categories available at Communica.
Capacitors are essential passive components in almost all electronic circuits, used for energy storage, filtering, decoupling, and timing. The 47uF 16V capacitor is a popular value in both analog and digital designs, particularly for power supply smoothing and decoupling purposes. It is commonly chosen because 47 microfarads is often sufficient to filter out voltage dips and noise, while 16 volts covers most low-voltage rails found in microcontroller, sensor, or audio circuits.
At 47uF and 16V, you will typically find three main capacitor types:
| Type | Polarity | Size | ESR | Typical Uses |
|---|---|---|---|---|
| Aluminum Electrolytic | Polarized | Larger | Medium/High | Bulk filtering, power rails |
| Tantalum | Polarized | Smaller | Low | Decoupling in compact designs |
| Ceramic (MLCC) | Non-polarized | Smallest (SMD) | Very Low | High-frequency bypassing |
When shopping at Communica, you'll notice all three types are available in both through-hole and SMD packages, depending on your assembly preference and space constraints. For hand-soldering or educational use, through-hole electrolytics are most popular. For compact or automated builds, consider SMD ceramics or tantalums.
Capacitor markings often show capacitance, voltage, and series codes. For example, a typical electrolytic will read "47uF 16V". Tantalum and ceramic SMD types may use a three-digit code.
Suppose you need to filter the 5V supply on a microcontroller board drawing 200mA. Choose a 47uF 16V electrolytic capacitor, rated for at least 150-200mA ripple current, with temperature rating >=85 degreesC. If the board is compact, a 47uF 16V SMD ceramic (X5R or better dielectric) provides low ESR for noise suppression.
+5V ----||---- GND ("||" = 47uF 16V electrolytic)
Installed near the microcontroller power pin to reduce supply noise.| Type | Best For | Popular Brands |
|---|---|---|
| Electrolytic | General, power rails | Panasonic, Nichicon, Rubycon |
| Tantalum | Space-tight designs | Kemet, Vishay, AVX |
| Ceramic MLCC | Low-ESR, noise filtering | Murata, Samsung, TDK |
