The QT532S-16.000MAHJ-T is a quartz crystal resonator manufactured by QST, operating at a nominal frequency of 16 MHz. It features a frequency stability of ±30ppm and a load capacitance of 18pF. The device exhibits an equivalent series resistance (ESR) of 40 Ohms and utilizes a 4-SMD, No Lead package with dimensions of 5.0mm x 3.2mm x 0.9mm. It is RoHS compliant and lead-free.
Verify the manufacturer marking on the component body to confirm authenticity as QST or TXC. Ensure the ordering suffix matches the required frequency tolerance and packaging format. Cross-reference the datasheet specifications against your circuit requirements before finalizing procurement orders.
Select this component when a 16 MHz surface-mount crystal with ±30ppm stability is required. Consider the 18pF load capacitance compatibility with the host oscillator circuit. Evaluate the 40 Ohm ESR against the driving level constraints of the application to ensure reliable operation.
This part belongs to the QT532S series of seam-sealed quartz crystals. The series offers various frequencies in a compact 5.0x3.2mm SMD package. It serves as a timing reference for digital systems requiring precise frequency generation without the complexity of active oscillators.
Compatible substitutes include other 16MHz SMD crystals with matching 18pF load capacitance and similar physical dimensions. Verify that alternative parts meet the ±30ppm stability requirement and operate within the -40°C to +85°C temperature range.
