DF18CC1-12.000MHZ-T

Crystals Overview

The DF18CC1-12.000MHZ-T is a surface-mount MHz crystal from the MMD D Series, operating at a nominal frequency of 12 MHz. It features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. The component provides a frequency tolerance of ±15 ppm and stability of ±30 ppm. Designed for fundamental mode operation, it utilizes an HC-49/US package with dimensions of 11.70mm x 5.00mm x 4.50mm maximum height. It supports reel, cut tape, and Digi-Reel packaging options.

Crystals Feature Summary

• Surface mount construction in standard HC-49/US package
• Fundamental mode operation for precise timing
• High frequency stability within specified temperature range

Crystals Applications

• General purpose clock generation circuits

• Digital communication interfaces

Crystals Procurement Notes

Verify the specific suffix against official MMD documentation to ensure the correct frequency and tolerance match the design requirements. Confirm that the HC-49/US surface mount footprint aligns with the PCB layout. Check for RoHS compliance status if required by project specifications. Ensure the selected packaging type (TR, CT, or Digi-Reel) matches the assembly equipment capabilities.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency with 18 pF load capacitance is required. Consider the 50 Ohm ESR value for oscillator circuit compatibility. The -40°C to +85°C operating range suits industrial applications. Verify that the surface mount profile fits within the mechanical constraints of the enclosure.

Crystals Part Context

This part belongs to the MMD D Series of crystals, which offers a wide frequency range from 3.2 MHz to 80 MHz. The series supports both fundamental and third overtone modes. These components are designed for high reliability and are often used in demanding electronic environments requiring stable frequency references.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz HC-49/US SMD crystals with matching 18 pF load capacitance and similar ESR values. Cross-reference with other manufacturers' HC-49/US SMD series for pin-compatible alternatives. Ensure any replacement meets the same frequency tolerance and stability specifications.
