T10GC1-30.000MHZ-T

Crystals Overview

The MMD T10GC1-30.000MHZ-T is a 30 MHz surface-mount quartz crystal oscillator in the T series, manufactured by Abracon (MMD). It features a compact 4-SMD, No Lead package with dimensions of 3.45 mm length, 2.75 mm width, and 0.75 mm height. The component operates within an industrial temperature range of -40°C to +85°C. Key electrical specifications include a frequency tolerance of ±10 ppm, frequency stability of ±30 ppm, a load capacitance of 10 pF, and an equivalent series resistance (ESR) of 50 Ohms. The device utilizes fundamental AT-cut mode operation.

Crystals Feature Summary

• Compact 3225-style SMD footprint suitable for space-constrained designs
• Industrial-grade temperature rating for reliable performance in harsh environments
• Low equivalent series resistance facilitating stable oscillation in low-power circuits

Crystals Applications

• General microcontroller unit (MCU) main clock generation
• Ethernet PHY reference clock sources
• Bluetooth and Wi-Fi peripheral timing references

Crystals Procurement Notes

Verify the manufacturer designation carefully, as the T-series is produced by Abracon under the MMD branding. Confirm that the specific lot documentation requirements align with project quality standards. Ensure the PCB land pattern matches the 3.45mm x 2.75mm outline to prevent soldering defects. Cross-reference the 10pF load capacitance requirement with the host circuit design to maintain frequency accuracy.

Crystals Selection Notes

Select this component when a 30 MHz fundamental frequency is required with ±10 ppm initial tolerance. The 50 Ohm ESR specification makes it suitable for applications where lower drive levels are preferred or where standard crystals might fail to start. Consider the -40°C to +85°C operating range for industrial deployments. Verify that the 10 pF load capacitance matches the oscillator circuit's input capacitance settings.

Crystals Part Context

This part belongs to the T series of surface-mount crystals from Abracon/MMD. The series covers frequencies from 12 MHz to 54 MHz, targeting general-purpose digital logic and communication interfaces. The T10GC1 variant specifically denotes the industrial grade with defined stability and aging characteristics, distinguishing it from commercial grade alternatives in the same physical package.

Crystals Replacement Considerations

Direct substitutes must match the 30 MHz frequency, 10 pF load capacitance, 4-SMD no-lead package, and 50 Ohm ESR. Verify that any alternative offers comparable ±10 ppm tolerance and -40°C to +85°C operating range. Check if the replacement supports fundamental AT-cut operation to ensure similar startup reliability.
