9B-32.000MAAJ-B

Crystals Overview

The TXC CORPORATION 9B-32.000MAAJ-B is a 32 MHz quartz crystal resonator designed for surface-mount or through-hole applications, depending on the specific variant configuration. It operates at the third overtone mode with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 80 Ohms. The component provides a frequency stability of ±30 ppm and a tolerance of ±30 ppm. It is housed in an HC-49/US package with dimensions of 20.5 mm x 4.6 mm x 7.0 mm. The device supports a standard operating temperature range of -20°C to +70°C and complies with RoHS3 specifications.

Crystals Feature Summary

• Third overtone operation for improved frequency stability
• HC-49/US package format for reliable mounting
• Compliance with RoHS3 environmental standards

Crystals Applications

• Clock signal generation in microcontroller circuits
• Timing references in communication modules
• Frequency control in consumer electronic devices

Crystals Procurement Notes

Verify the exact package type and pin configuration against the official datasheet before procurement, as HC-49 variants may differ in lead style. Confirm that the third overtone requirement aligns with the oscillator circuit design, as this component does not operate in fundamental mode. Ensure the loading capacitors in the target circuit match the specified 18 pF load capacitance to achieve the stated ±30 ppm stability. Check for any specific handling instructions regarding moisture sensitivity if applicable.

Crystals Selection Notes

Select this component when a stable 32 MHz reference is required in space-constrained designs utilizing HC-49 packages. The third overtone characteristic makes it suitable for applications where higher frequency accuracy is needed without increasing the physical size significantly. Consider the 80 Ohm ESR value when designing the oscillator circuit to ensure sufficient loop gain. Verify compatibility with the operating temperature range of -20°C to +70°C for the intended environment.

Crystals Part Context

The 9B series represents a line of quartz crystals from TXC Corporation, typically characterized by their robust construction and consistent performance. This specific model falls under the MHz Crystal category, distinct from oscillators or resonators, requiring an external oscillator circuit to function. The HC-49/US package is a widely recognized standard in the industry, facilitating easy integration into existing PCB layouts and manufacturing processes.

Crystals Replacement Considerations

Direct substitutes must match the 32 MHz frequency, 18 pF load capacitance, 80 Ohm ESR, and HC-49/US package. Verify that any replacement also supports third overtone operation and meets the ±30 ppm stability requirement. Cross-reference the pinout and mechanical dimensions to ensure compatibility with the existing footprint.
