7A-27.000MAHE-T

Crystals Overview

The 7A-27.000MAHE-T is a surface-mount MHz crystal manufactured by TXC Corporation, operating at a nominal frequency of 27.000MHz. It features a load capacitance of 12pF and a frequency stability of ±30ppm. The component utilizes a 4-SMD, No Lead package with dimensions of 5.00mm x 3.20mm. It supports fundamental mode operation and has an equivalent series resistance (ESR) of 60 Ohms. The device is rated for an operating temperature range of -40°C to +85°C.

Crystals Feature Summary

• Fundamental mode quartz crystal resonator
• Surface mount 4-SMD no lead package
• Wide industrial temperature rating

Crystals Applications

• Clock signal generation in embedded systems
• Frequency reference for microcontrollers
• Communication module timing circuits

Crystals Procurement Notes

Verify the specific ESR value against the official datasheet, as sources indicate variations between 50 and 60 Ohms. Confirm RoHS compliance status directly from the manufacturer documentation. Ensure the selected variant matches the required temperature range and package dimensions for your PCB layout.

Crystals Selection Notes

Select this component when a 27MHz fundamental frequency reference is required in a compact surface-mount form factor. Consider the ±30ppm stability requirement for your application's clock tolerance. Verify that the 12pF load capacitance aligns with your circuit design specifications.

Crystals Part Context

This part belongs to the 7A series of crystals from TXC Corporation. It serves as a passive frequency control element within oscillator circuits. The 4-SMD package allows for automated assembly processes. It is distinct from MEMS oscillators and other crystal series like 7M or TA.

Crystals Replacement Considerations

The 7M-27.000MAHE-T is a similar 27MHz crystal from the same manufacturer but uses a smaller 3.2x2.5mm package. Verify mechanical fit and electrical parameters before substitution.
