9B-25.000MBBK-B

Crystals Overview

The TXC Corporation 9B-25.000MBBK-B is a through-hole parallel fundamental quartz crystal resonator designed for standard clock applications. It operates at a nominal frequency of 25.000 MHz with a load capacitance of 20 pF and a frequency tolerance of ±50 ppm. The component utilizes the HC-49/S package, measuring 11.5 mm in length and 5 mm in width. It supports an operating temperature range from -10°C to +70°C and complies with RoHS standards.

Crystals Feature Summary

• Parallel fundamental quartz crystal construction
• Through-hole mounting via HC-49/S package
• Standard CMOS clock oscillator compatibility

Crystals Applications

• General purpose timing circuits
• Microcontroller clock sources
• Consumer electronics control boards

Crystals Procurement Notes

Verify the specific suffix 'BBK-B' against the manufacturer's current datasheet to confirm active status and exact pin configuration. Ensure the target circuit design accommodates through-hole assembly requirements and matches the 20 pF load capacitance specification for accurate frequency operation.

Crystals Selection Notes

Select this component when through-hole reliability is prioritized over surface-mount density. Confirm that the system environment remains within the -10°C to +70°C operational range. Validate that the ±50 ppm frequency tolerance meets the timing accuracy requirements of the host application.

Crystals Part Context

This part belongs to the 9B series of quartz crystals from TXC Corporation. It serves as a passive frequency-determining element, distinct from active oscillators. The HC-49/S form factor is widely used in legacy and industrial designs requiring robust mechanical stability and ease of manual or wave soldering.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49/S crystals with identical 25 MHz frequency, 20 pF load capacitance, and ±50 ppm tolerance. Verify that replacement parts maintain the same physical dimensions and electrical characteristics to ensure board compatibility.
