7M-30.000MAHE-T

Crystals Overview

The 7M-30.000MAHE-T is a fundamental mode quartz crystal resonator manufactured by TXC Corporation, operating at a nominal frequency of 30 MHz. It features a load capacitance of 12 pF and an equivalent series resistance (ESR) of 60 Ohms. The component exhibits a frequency tolerance and stability of ±30 ppm across a temperature range of -40°C to +85°C. It utilizes a 4-SMD, no-lead package with dimensions of 3.20 mm in length, 2.50 mm in width, and a maximum height of 0.80 mm. The device supports surface mount installation and operates in the fundamental mode.

Crystals Procurement Notes

Verify the specific suffix HE against the manufacturer's official part number guide to ensure correct load capacitance and packaging specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the bill of materials. Cross-reference the datasheet for any recent updates regarding pin configuration or recommended soldering profiles to guarantee assembly reliability.

Crystals Selection Notes

Select this component when a 30 MHz fundamental frequency with ±30 ppm stability is required within the -40°C to +85°C operational range. Ensure the circuit design accommodates the specified 12 pF load capacitance and 60 Ohm ESR characteristics. Verify that the PCB footprint matches the 3.2x2.5 mm SMD package dimensions and that the application does not require higher precision tolerances than provided.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation, designed for surface mount applications. The series covers frequencies from 10 MHz to 114.285 MHz. The 7M-30.000MAHE-T specifically addresses the common 30 MHz requirement using a standard 4-SMD no-lead form factor, offering a balance of performance and size for embedded systems.

Crystals Replacement Considerations

Direct substitutes include other 30 MHz crystals with identical 12 pF load capacitance, ±30 ppm tolerance, and 3.2x2.5 mm SMD footprint. Verify electrical parameters such as ESR and frequency stability match before substitution. Alternative packages may require PCB re-layout.
