7B-10.000MAAE-T

Crystals Overview

The TXC Corporation 7B-10.000MAAE-T is a surface-mount quartz crystal resonator operating at a fundamental frequency of 10.000 MHz. It features a standard load capacitance of 12 pF and maintains a frequency tolerance and stability of ±30 ppm across the commercial temperature range of -20°C to +70°C. The component utilizes a compact 4-SMD, no-lead package with dimensions of 5.00 mm in length, 3.20 mm in width, and a maximum height of 1.05 mm. Designed for base harmonic operation, it exhibits an equivalent series resistance (ESR) of 40 Ohms. This device complies with RoHS3 standards and carries an MSL rating of Level 1.

Crystals Procurement Notes

This specific part number is officially obsolete and no longer manufactured by TXC Corporation. Procurement must focus on identifying verified substitute components from the manufacturer's current portfolio or authorized distributors. Verify that replacement parts match the original electrical parameters, specifically the 10 MHz frequency, 12 pF load capacitance, and 40 Ohm ESR requirements to ensure circuit compatibility.

Crystals Selection Notes

Engineers should prioritize replacement crystals within the same 7B series family to maintain consistent physical dimensions and mounting profiles. Ensure the substitute component supports the required 10 MHz fundamental mode and matches the 12 pF load capacitance specification. Verify that the alternative part meets the necessary ±30 ppm frequency stability and operates reliably within the -20°C to +70°C environmental range intended for the application.

Crystals Part Context

The 7B-10.000MAAE-T belongs to the TXC 7B series of seam-welded surface-mount crystals. This series is engineered for high performance in consumer electronics and wireless communications. The 5x3.2 mm package size represents a significant reduction compared to traditional through-hole packages, facilitating automated assembly and denser circuit board designs while maintaining robust mechanical integrity.

Crystals Replacement Considerations

Available substitutes include the 7M-10.000MAAE-T and other similar variants from TXC Corporation. These replacements offer comparable electrical specifications but may differ in physical package dimensions or manufacturing series. Validate pinout compatibility and thermal characteristics before implementation.
