Q14.74560-SMU4-30-30/30LF – JAUCH QUARTZ AMERICA INC

The Q14.74560-SMU4-30-30/30LF is a 14.7456 MHz quartz crystal resonator manufactured by JAUCH Quartz America, Inc. It is a through-hole mounted device, conforming to a standard HC-49/US package outline. The “SMU4” likely refers to a specific crystal cut and manufacturing process optimized for stability and low aging characteristics. The “30-30/30LF” denotes a load capacitance of 30 pF, a series resistance (ESR) of 30 ohms, and that the device is lead-free (LF) and RoHS compliant, as indicated by the “2007 ROHS” designation, suggesting compliance with the 2002/95/EC directive and subsequent amendments. This crystal is suitable for applications requiring a precise and stable frequency reference, such as microcontrollers, communication systems, and real-time clocks.
