7B-27.000MEEQ-T

Crystals Overview

The 7B-27.000MEEQ-T is a surface-mount fundamental mode quartz crystal manufactured by TXC Corporation. It operates at a nominal frequency of 27 MHz with a load capacitance of 10 pF and an equivalent series resistance (ESR) of 40 Ohms. The component provides high frequency stability and tolerance, both rated at ±10 ppm. Designed for industrial applications, it functions within a temperature range of -20°C to +70°C. The device utilizes a 4-SMD, no lead package with dimensions of 3.20 mm x 2.50 mm and a maximum height of 0.80 mm.

Crystals Feature Summary

Crystals Procurement Notes

Verify the current lifecycle status before procurement, as this specific part number may be obsolete or discontinued. Confirm that the 4-SMD package dimensions align with existing PCB footprints. Ensure the 10 pF load capacitance matches the oscillator circuit design specifications. Check for RoHS compliance documentation if required for regulatory standards. Validate availability through authorized distributors due to potential supply constraints.

Crystals Selection Notes

Select this component when a fundamental mode crystal with ±10 ppm stability is required. The 10 pF load capacitance must match the system's oscillator circuit. Consider the 40 Ohm ESR value for drive level sensitivity. The -20°C to +70°C range defines the operational limits. Compare against the 7M series for alternative packaging or performance options if this model is unavailable.

Crystals Part Context

This component belongs to the 7B series of quartz crystals from TXC Corporation. It is designed for general-purpose timing applications in electronic circuits. The 7B series typically offers reliable performance in consumer and industrial markets. This specific variant focuses on the 27 MHz frequency band with standard SMD packaging.

Crystals Replacement Considerations

The 7M-27.000MEEQ-T serves as a direct substitute, offering identical electrical parameters including 27 MHz frequency, 10 pF load capacitance, and ±10 ppm stability. Both components share the same 4-SMD package outline. Verify that the ESR specification meets the circuit requirements, as variations may exist between series.
