7R-30.000MDAQ-T

Crystals Overview

The TXC Corporation 7R-30.000MDAQ-T is a surface-mount glass-sealed quartz crystal resonator operating at a fundamental frequency of 30 MHz. It features a compact 4-SMD, no-lead package with dimensions of 2.05 mm in length and 1.65 mm in width. The component exhibits a frequency tolerance of ±20 ppm at 25°C and maintains stability within ±30 ppm across the commercial temperature range of -20°C to +70°C. It utilizes a 10 pF load capacitance and has an equivalent series resistance (ESR) of 120 Ohms.

Crystals Feature Summary

• Glass-sealed construction for environmental protection
• Compact 2.0x1.6 mm SMD footprint
• Fundamental mode operation

Crystals Applications

• General purpose clock signal generation
• Microcontroller timing circuits
• Communication module reference clocks

Crystals Procurement Notes

Verify the specific suffix 'MDAQ' against official TXC documentation to confirm the exact tolerance and temperature specifications. Ensure the target application supports the -20°C to +70°C operating range. Confirm that the 10 pF load capacitance matches the circuit design requirements before finalizing procurement.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The glass seal offers durability compared to standard ceramic packages. Consider the ESR value for oscillator circuit compatibility. This part is suitable for applications where space constraints are critical but high-precision industrial temperature ranges are not mandatory.

Crystals Part Context

This model belongs to the 7R series of MHz quartz crystals from TXC Corporation. These components are designed as direct replacements for larger through-hole or standard SMD crystals in modern miniaturized electronics. The series emphasizes reliability through glass sealing technology while maintaining a low profile suitable for dense PCB layouts.

Crystals Replacement Considerations

Direct substitutes include the 7R-30.000MDA-T variant, which shares similar physical dimensions and electrical characteristics. Verify that any replacement maintains the 10 pF load capacitance and 120 Ohm ESR to ensure circuit oscillation stability without modification.
