7R-20.736MEDC-T

Crystals Overview

The 7R-20.736MEDC-T is a MHz quartz crystal resonator manufactured by TXC Corporation, designed for surface-mount applications. It operates at a nominal frequency of 20.7360 MHz with a load capacitance of 9 pF. The component features a compact 4-SMD, no lead package with body dimensions of 2.0 x 1.6 x 0.6 mm. Frequency stability is rated at ±10 ppm at 25°C and ±20 ppm over the operating temperature range of -20°C to +70°C. The equivalent series resistance is specified as 200 Ohms.

Crystals Feature Summary

• Utilizes glass seal technology for enhanced environmental protection and reliability in quartz crystal construction.
• Offers precise frequency tolerance of ±10 ppm at room temperature for accurate timing control.
• Features a compact 4-pad surface-mount footprint suitable for space-constrained PCB layouts.

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Crystals Procurement Notes

Verify the complete part number including the trailing suffix to ensure correct packaging and tape-and-reel specifications. Confirm that the load capacitance requirements of the host circuit match the 9 pF specification of this component. Check for any specific handling instructions related to the glass seal construction during assembly processes.

Crystals Selection Notes

Select this component when a stable 20.736 MHz reference is required in a small SMD form factor. Ensure the application environment stays within the -20°C to +70°C range to maintain the ±20 ppm stability rating. Consider the 200 Ohm ESR when designing oscillator circuits to guarantee reliable startup conditions.

Crystals Part Context

This part belongs to the 7R series of MHz quartz crystals from TXC Corporation. These components are engineered for general-purpose timing applications where moderate stability and a small physical profile are prioritized. The series utilizes standard AT-cut quartz elements housed in hermetically sealed packages.

Crystals Replacement Considerations

Direct substitutes must match the 20.736 MHz frequency, 9 pF load capacitance, and 2.0x1.6mm package dimensions. Verify that alternative manufacturers offer comparable ±10 ppm initial tolerance and similar ESR values to ensure circuit compatibility without redesign.
