7R-25.000MEIK-T

Crystals Overview

The 7R-25.000MEIK-T is a MHz quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a fundamental frequency of 25.000 MHz with a load capacitance of 20 pF. The component features a glass seal package in a 2.0 x 1.6 mm footprint and utilizes a four-pad SMD configuration without leads. Frequency stability is specified at ±10 ppm at 25°C and ±20 ppm over the -40°C to +85°C temperature range.

Crystals Feature Summary

• Ultra-miniature glass seal construction for high reliability
• Four-pad surface mount design for automated assembly
• High accuracy frequency stability across industrial temperatures

Crystals Applications

• Precision timing circuits requiring compact form factors
• Consumer electronics with strict space constraints
• Industrial control systems operating in variable thermal environments

Crystals Procurement Notes

Verify the specific suffix 'MEIK' against official TXC documentation to confirm the glass seal variant and pad configuration. Ensure compatibility with the target PCB land pattern dimensions of 2.0 x 1.6 mm. Confirm that the 20 pF load capacitance aligns with the oscillator circuit requirements before finalizing procurement.

Crystals Selection Notes

Select this component when a small footprint and high stability are required. The glass seal offers superior environmental protection compared to ceramic alternatives. Consider the four-pad layout for solder joint integrity. Verify that the ±20 ppm stability meets the system's jitter and clock accuracy specifications.

Crystals Part Context

This part belongs to the 7R series of ultra-miniature crystals from TXC Corporation. The series focuses on providing high Q-factor and low phase noise characteristics within a reduced physical size. It serves as a frequency reference solution for modern portable and embedded devices where space is limited.

Crystals Replacement Considerations

Direct substitutes must match the 2.0 x 1.6 mm glass seal package and 20 pF load capacitance. Verify that alternative parts maintain the same four-pad SMD configuration and ±20 ppm stability range to ensure electrical and mechanical compatibility.
