The QT49-48.000MAAE-B is a 48 MHz quartz crystal manufactured by QST, designed for through-hole mounting in the HC-49/US package. It features a frequency stability of ±30ppm and a load capacitance of 12pF. The component exhibits an equivalent series resistance (ESR) of 80 Ohms and operates within a temperature range of -40°C to +85°C. This fundamental mode crystal is suitable for precision timing applications requiring reliable frequency generation.
Verify that the specific suffix AAE corresponds to the required 12pF load capacitance and 80 Ohm ESR specifications. Confirm that the HC-49/US through-hole package aligns with the target PCB layout requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Cross-reference the manufacturer part number against official QST documentation to validate availability and lead times.
