7M-48.000MAHC-T

Crystals Overview

The TXC Corporation 7M-48.000MAHC-T is a parallel fundamental quartz crystal operating at a nominal frequency of 48 MHz. It features a frequency tolerance and stability of ±30 ppm, with a load capacitance of 9 pF. The component has an equivalent series resistance (ESR) of 60 Ohms and operates within a temperature range of -40°C to +85°C. It utilizes a surface-mount package measuring 3.2 mm in length, 2.5 mm in width, and 0.7 mm in height. The unit weight is 16 mg, and it supports a maximum shunt capacitance of 3 pF.

Crystals Feature Summary

• Fundamental mode parallel resonance operation for stable frequency generation
• Surface-mount design compatible with automated assembly processes
• Wide industrial temperature rating ensuring reliability across varying thermal conditions

Crystals Applications

• Microcontroller clock sources requiring precise timing references
• Communication interfaces utilizing standard baud rates derived from 48 MHz
• Industrial control systems operating in extended temperature environments

Crystals Procurement Notes

Verify the specific load capacitance requirement of the host oscillator circuit against the 9 pF specification to ensure frequency accuracy. Confirm that the application environment remains within the -40°C to +85°C operational range. Check for RoHS compliance documentation if environmental regulations apply. Ensure the PCB footprint matches the 3.2 x 2.5 mm SMD package dimensions. Validate that the driving level does not exceed the specified limits to prevent frequency drift or damage.

Crystals Selection Notes

Select this component when a 48 MHz reference is required with moderate stability needs. Consider the 30 ppm tolerance for applications where tighter precision is unnecessary. Evaluate the 60 Ohm ESR against the oscillator circuit's drive capability. Compare physical size constraints against alternative packages if space is limited. Assess temperature requirements to confirm the industrial grade meets the deployment environment.

Crystals Part Context

This part belongs to the 7M series of high-precision quartz crystals manufactured by TXC Corporation. The series is designed for general-purpose timing applications requiring reliable performance in surface-mount configurations. The 7M designation indicates a specific family of fundamental mode crystals optimized for cost-effective integration into consumer and industrial electronics.

Crystals Replacement Considerations

The 7M-48.000MAHV-T is a documented substitute within the same series, featuring an 8 pF load capacitance instead of 9 pF. Verify circuit compatibility regarding load capacitance differences before substitution. Other variants in the 7M series may offer different tolerances or packaging options.
