DF18CC1-25.000MHZ-T

Crystals Overview

The MMD DF18CC1-25.000MHZ-T is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 25 MHz with an HC-49/US package footprint. The component features a load capacitance of 18 pF and offers a frequency tolerance of ±15 ppm at 25°C. Frequency stability is rated at ±30 ppm over the operating temperature range of -40°C to +85°C. Equivalent series resistance (ESR) is specified at 30 Ohms, with a maximum drive level of 1 mW. Physical dimensions are 11.7 mm in length, 4.8 mm in width, and 4.5 mm in height.

Crystals Feature Summary

• Fundamental mode operation within an HC-49/US surface-mount package
• High frequency stability across extended industrial temperature ranges
• Low equivalent series resistance for efficient circuit integration

Crystals Applications

• Microcontroller clock generation circuits
• Communication interface timing references
• Digital signal processing system clocks

Crystals Procurement Notes

Verify that the specific order matches the MMD manufacturer part number DF18CC1-25.000MHZ-T, as identical specifications exist under ABRACON branding. Confirm RoHS compliance status through official datasheets prior to procurement. Ensure supply chain sources provide valid traceability documentation for quality assurance purposes.

Crystals Selection Notes

Select this component when a standard HC-49/US footprint is required for surface-mount assembly processes. The 18 pF load capacitance must match the oscillator circuit design requirements. Verify that the ±15 ppm tolerance meets the system's timing accuracy constraints. Consider the 30 Ohm ESR value for driver circuit compatibility.

Crystals Part Context

This component belongs to the D Series family of quartz crystals manufactured by MMD. It represents a transition from traditional through-hole HC-49/U packages to surface-mount variants while maintaining similar electrical characteristics. The product line supports high-volume manufacturing needs for consumer and industrial electronics requiring precise timing signals.

Crystals Replacement Considerations

Substitutes must maintain the HC-49/US SMD footprint and 18 pF load capacitance. Compatible alternatives include other manufacturers' 25 MHz crystals with matching ±15 ppm tolerance and ≤30 Ohm ESR specifications.
