HC-49US 14.7456 MHz Quartz Crystal | 20pF | 20PPM | DIP Through-Hole

Description

The HC-49US 14.7456 MHz Crystal is a high-precision quartz resonator, highly valued in embedded systems design for its unique frequency. In digital communication applications, 14.7456 MHz is a “preferred” frequency because it is a direct multiple of standard serial (UART) baud rates. Using this crystal allows microcontrollers to generate precise bit rates—such as 9600, 19200, 38400, and 115200 bps—with virtually zero percentage error, effectively eliminating common framing errors in serial data transmission.

Housed in the industry-standard HC-49US 2-pin through-hole package, this crystal offers excellent mechanical durability and electrical stability. Its hermetically sealed, resistance-welded construction provides superior protection against environmental factors like oxidation and humidity. With a tight 20 PPM frequency tolerance and a standard 20 pF load capacitance, it delivers the consistent, low-jitter clock performance necessary for robust digital and communication hardware.

Key Features

• Perfect for UART/Serial Comms: Its 14.7456 MHz frequency is mathematically ideal for generating standard baud rates with negligible error.
