Description
The YXC HC-49US 4.192 MHz Crystal is a precision-engineered quartz resonator, valued for its stable frequency output in embedded timing applications. Operating at 4.192 MHz, this crystal is commonly found in microcontroller-based systems where a reliable base frequency is required for timing loops, real-time counters, or general-purpose clock generation.
Housed in the industry-standard HC-49US 2-pin through-hole package, this crystal is highly regarded for its physical durability and ease of integration into breadboards, development boards, and professional PCB designs. Its hermetically sealed, resistance-welded enclosure ensures excellent protection against environmental degradation, such as humidity or thermal expansion. With a tight 20 PPM frequency tolerance and a 20 pF load capacitance, it provides the low-jitter performance essential for synchronized digital communication.
Key Features
- Reliable Frequency Reference: 4.192 MHz nominal frequency ideal for stable timing in embedded systems.
