7M-20.000MAHI-T

Crystals Overview

The 7M-20.000MAHI-T is a surface-mount quartz crystal oscillator manufactured by TXC Corporation, designed for commercial applications. It operates at a fundamental frequency of 20 MHz with a load capacitance of 16 pF and an equivalent series resistance (ESR) of 60 Ohms. The component provides a frequency stability and tolerance of ±30 ppm across an operating temperature range of -40°C to +85°C. Housed in a compact 4-SMD, no-lead package measuring 3.20 mm x 2.50 mm with a maximum height of 0.80 mm, it supports RoHS3 compliance and MSL level 1 moisture sensitivity.

• Integrated enable/disable functionality within the oscillator circuit

Crystals Applications

• General purpose digital clock signal generation
• Microcontroller system timing references
• Communication interface synchronization
• Consumer electronic device clocks

Crystals Procurement Notes

Verify the specific load capacitance requirement of 16 pF against the target circuit design to ensure accurate frequency performance. Confirm that the PCB footprint matches the 3.20 mm x 2.50 mm dimensions and the 0.80 mm maximum height constraint. Ensure the application environment remains within the specified -40°C to +85°C operating range to maintain the stated ±30 ppm stability. Check for RoHS3 compliance requirements if restricted substances are prohibited in the final product assembly process.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±30 ppm stability is required for commercial-grade applications. The 16 pF load capacitance specification must align with the host circuit's capacitive loading to prevent frequency drift. Consider the 60 Ohm ESR value for oscillator circuit compatibility. The 4-SMD package offers space efficiency compared to larger through-hole alternatives, suitable for dense PCB layouts where vertical space is limited to under 1 mm.

Crystals Part Context

This part belongs to the 7M series of quartz crystals from TXC Corporation, which focuses on standard frequency components for general electronics. The series utilizes fundamental mode vibration for reliable performance at frequencies up to approximately 114 MHz. The 7M series is characterized by its small form factor and suitability for high-volume surface mount manufacturing processes, providing a balance between cost-effectiveness and consistent electrical characteristics for mainstream consumer and industrial devices.

Crystals Replacement Considerations

The 7V-20.000MAHE-T is listed as a direct substitute by the manufacturer. Verify pinout compatibility and exact parameter matching before implementation.
