7V-27.000MDDJ-T

Crystals Overview

The TXC Corporation 7V-27.000MDDJ-T is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 27 MHz with a load capacitance of 18 pF and a frequency tolerance of ±20 ppm. The component features an equivalent series resistance (ESR) of 60 Ohms and functions within a temperature range of -20°C to +70°C. It utilizes a 4-SMD, no-lead package measuring 3.20 mm in length, 2.50 mm in width, and 0.90 mm in maximum height.

Crystals Feature Summary

• Fundamental mode quartz crystal operation
• Surface-mount 4-SMD no-lead package configuration
• Stable frequency output for timing sources

Crystals Applications

• Low-power embedded designs
• General-purpose timing source circuits
• Consumer electronics requiring 27 MHz reference

Crystals Procurement Notes

Verify the specific suffix 'MDDJ' against official TXC documentation to confirm the exact electrical parameters, particularly the 18 pF load capacitance and ±20 ppm tolerance. Ensure the operating temperature range of -20°C to +70°C aligns with the target application environment. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement specifications.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 27 MHz applications with moderate stability needs. The 18 pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C temperature range suitability. The compact 3.2x2.5 mm footprint is appropriate for space-constrained PCB layouts where surface-mount technology is preferred over through-hole alternatives.

Crystals Part Context

This part belongs to the 7V series of ceramic crystals from TXC Corporation. It is distinct from MEMS oscillators like the TA series or VCXOs like the 6U series. The 7V series generally offers fundamental mode operation suitable for cost-sensitive applications requiring standard crystal performance without the integrated circuitry found in active oscillators.
