9B-25.000MAAJ-B

Crystals Overview

The TXC Corporation 9B-25.000MAAJ-B is a through-hole quartz crystal resonator operating at a fundamental frequency of 25 MHz. It features an HC-49/S package with radial leads and a bulk packaging style. The component exhibits a frequency tolerance and stability of ±30 ppm across the commercial temperature range of -20°C to +70°C. Designed for standard circuit integration, it utilizes a load capacitance of 18 pF and maintains an equivalent series resistance (ESR) of 30 Ohms. The device supports a maximum drive level of 100 µW and measures 11.5 mm in length, 5 mm in width, and 3.68 mm in height.

Crystals Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited supply conditions. Confirm that the HC-49/S package dimensions and lead spacing match the target PCB footprint requirements. Ensure the 18 pF load capacitance aligns with the host circuit design specifications before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a through-mount solution is required for 25 MHz applications. Consider the HC-49/S form factor for compatibility with existing legacy board layouts. Evaluate the ±30 ppm stability against system timing requirements to ensure adequate performance margins for the intended operational environment.

Crystals Part Context

This part belongs to the 9B product family from TXC Corporation, which specializes in general-purpose quartz crystals. The 9B series typically offers standard frequencies in through-hole packages suitable for cost-sensitive consumer electronics and industrial control systems requiring basic timing precision.

Crystals Replacement Considerations

For direct replacement, consider the 9B-25.000MDXT-T variant if surface mount technology is acceptable. Verify that any substitute maintains the same 25 MHz frequency, 18 pF load capacitance, and HC-49/S mechanical dimensions to ensure electrical and physical compatibility.
