Product Description (Detailed):
Ensure precise frequency tuning and stable oscillation in your electronic circuits with our essential 22pF 50V Ceramic Capacitor. This small yet critical component, often known as a 22 picofarad capacitor, is primarily recognized for its vital role in supporting crystal oscillators and in high-frequency applications. Housed in a compact DIP (Dual In-line Package) or disc configuration with through-hole leads, it's perfectly suited for a wide range of electronic designs.
Ceramic capacitors are renowned for their excellent high-frequency characteristics, low equivalent series resistance (ESR), and minimal inductance, making them ideal for bypassing high-frequency noise and for use in resonant circuits. The 22pF capacitance value is particularly common and often specified as the "load capacitance" for quartz crystal oscillators (e.g., 16 MHz or 20 MHz crystals) when building the clock circuit for microcontrollers like Arduino, PIC, or AVR. These small capacitors work in conjunction with the crystal to ensure it oscillates precisely at its rated frequency, providing the stable timing reference crucial for digital operations, communication protocols, and accurate execution of code.
With a robust 50V voltage rating, this ceramic capacitor offers ample safety margin for typical low-voltage digital and analog circuits operating from 3.3V, 5V, 12V, or 24V power supplies. Its non-polarized nature simplifies circuit assembly, as there's no specific orientation requirement for installation. The through-hole design allows for easy insertion into breadboards for prototyping and secure soldering onto printed circuit boards (PCBs) for permanent applications. Beyond crystal oscillators, this 22pF ceramic capacitor finds use in RF circuits, filter networks, and anywhere precise small capacitance is required to maintain signal integrity or shape frequency response.
The 22pF 50V Ceramic Capacitor is a disc-type capacitor used in high-frequency applications, particularly with crystal oscillators in microcontrollers and timing circuits. It features radial DIP leads for easy soldering and prototyping on both breadboards and PCBs.
With its low inductance, high stability, and temperature-resilient ceramic dielectric, it is ideal for resonance, signal coupling, filtering, and noise reduction tasks in both analog and digital circuits. These capacitors are standard components in Arduino crystal setups (16MHz XTAL with ATmega328P) and other clock generation modules.
