T10GC1-40.000MHZ-T

Crystals Overview

The T10GC1-40.000MHZ-T is a surface-mount crystal oscillator manufactured by MMD, designed for industrial applications. It operates at a nominal frequency of 40 MHz with a frequency tolerance of ±10 ppm and stability of ±30 ppm across the operating temperature range of -40°C to +85°C. The device utilizes a standard 3225 SMD package (3.2mm x 2.5mm) and supports a load capacitance of 10 pF. It features a maximum equivalent series resistance (ESR) of 50 Ohms in the base fundamental AT-cut mode. The component is RoHS compliant and suitable for compact designs requiring reliable clock signals.

Crystals Procurement Notes

Verify that the specific part number matches the required frequency tolerance and stability specifications for your application. Confirm the operating temperature range aligns with environmental conditions. Ensure the load capacitance requirement matches the system design. Check for RoHS compliance if exporting to regulated regions. Validate package dimensions against PCB footprint requirements.

Crystals Selection Notes

Select this component when a compact 3225 SMD form factor is required for industrial-grade timing. Consider the ESR value of 50 Ohms for low-power sleep mode reliability. Ensure the 40 MHz frequency fits the MCU or communication interface needs. Verify that the ±30 ppm stability meets synchronization requirements. Compare against commercial grade options if wide temperature operation is not necessary.

Crystals Part Context

This model belongs to the T-series of surface-mount crystals from MMD. It is distinct from the MLH series oscillators which offer hermetic sealing and wider frequency ranges. The T-series focuses on cost-effective, compact solutions for general industrial use. It shares the 3225 package dimension with other variants in the lineup but differs in electrical parameters and stability ratings.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching frequency, tolerance, stability, package size, and load capacitance. Verify compatibility with existing PCB footprints and driver circuits before substitution.
