What are the main features of the ECS-200-18-4X?
The ECS-200-18-4X is a 20 MHz quartz crystal designed for stable and accurate frequency generation. It offers a frequency tolerance of ±30 ppm, ensuring reliable timing performance in most general-purpose applications. The device is specified with an 18 pF load capacitance and 30 ohms equivalent series resistance, which helps maintain efficient oscillation. It is housed in a standard HC-49/US through-hole package, making it easy to integrate into a wide variety of circuit designs.
What is this part typically used for?
This crystal is commonly used as a clock source in microcontrollers, communication equipment, and digital circuits. It plays a critical role in maintaining precise timing for data processing, signal synchronization, and system control. Typical applications include consumer electronics, embedded systems, industrial controllers, and networking devices where stable clock signals are essential for proper operation.
Does it have alternative parts?
Yes, there are many alternative crystals available with similar specifications. Equivalent 20 MHz crystals with ±30 ppm tolerance, 18 pF load capacitance, and HC-49/US package from manufacturers such as Epson, TXC, or Citizen can often be used as substitutes. When selecting an alternative, it is important to match key parameters like frequency stability, load capacitance, ESR, operating temperature range, and package type to ensure compatibility and consistent performance.
