7M48070012

Crystals Overview

The TXC Corporation 7M48070012 is a surface-mount quartz crystal resonator housed in a 3.2 x 2.5 mm SMD package. It operates at a nominal frequency of 48 MHz with an 8 pF load capacitance. The device provides a frequency tolerance of ±10 ppm and stability of ±15 ppm across the industrial temperature range of -40°C to +85°C. Key electrical characteristics include a maximum equivalent series resistance (ESR) of 50 Ohms and a typical drive level of 100 µW. The component complies with RoHS standards and features MSL Level 1 moisture sensitivity, allowing direct use without pre-soldering baking.

Crystals Feature Summary

• AT-cut thickness shear mode construction for stable thermal drift performance
• Industrial-grade operational temperature range suitable for demanding environments
• RoHS compliant manufacturing process ensuring environmental safety

Crystals Applications

• Microcontroller unit clock generation circuits
• Ethernet PHY interface timing references
• General-purpose digital logic synchronization

Crystals Procurement Notes

Verify that the specific ordering suffix corresponds to mass production versions rather than engineering samples. Confirm the load capacitance specification matches the target circuit design requirements to prevent frequency deviation issues during implementation.

Crystals Selection Notes

Select this component when a standard 48 MHz reference signal is required within a compact footprint. Ensure the application environment remains within the specified -40°C to +85°C operating limits. Verify that the system oscillator can support the maximum ESR value without compromising startup reliability.

Crystals Part Context

This part belongs to the TXC 7M series of surface-mount crystals. It utilizes a缝焊 (seam-welded) technology structure common in industrial-grade resonators. The 3225 package size allows for automated pick-and-place assembly in high-volume consumer and industrial electronics manufacturing.

Crystals Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 8 pF load capacitance, and 3225 package dimensions. Cross-reference datasheets for identical ESR and stability specifications to ensure functional equivalence in existing designs.
