D-F-18.432M-18-3050-1070-40

Crystals Overview

The CEC Xtal D-F-18.432M-18-3050-1070-40 is a surface-mount quartz crystal resonator designed for precision timing applications. It operates at a fundamental frequency of 18.432 MHz with a frequency tolerance of ±30 ppm. The component features a load capacitance of 18 pF and utilizes a four-terminal no-lead SMD package with dimensions of 3.0 mm by 5.0 mm. This device provides stable oscillation characteristics suitable for integration into compact electronic circuits requiring reliable clock signals.

Crystals Feature Summary

• Four-terminal no-lead surface mount construction
• Precision frequency stability within ±30 ppm tolerance
• Optimized for compact circuit board layouts

Crystals Applications

• Digital communication systems
• Microcontroller clock sources
• Consumer electronics timing circuits

Crystals Procurement Notes

Verify the specific manufacturer designation when sourcing, as CEC Xtal products may be distributed under various branding or subsidiary names. Confirm that the four-terminal no-lead package matches your PCB footprint requirements. Ensure the 18 pF load capacitance aligns with your oscillator circuit design to maintain the specified ±30 ppm accuracy. Cross-reference the part number with official distributor catalogs to confirm current availability and authenticity.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 18.432 MHz frequency is standard for baud rate generation in serial communications. The four-terminal design offers improved performance over two-terminal variants in certain high-stability applications. Evaluate the 18 pF load capacitance against your system's parasitic capacitance to ensure accurate frequency operation.

Crystals Part Context

This crystal belongs to the family of surface-mount quartz resonators used for providing reference frequencies in digital electronics. Unlike voltage-controlled oscillators, this component requires an external oscillator circuit to generate a square wave output. It serves as a passive timing element essential for synchronizing data transmission and processing operations in embedded systems.

Crystals Replacement Considerations

Substitutes must match the 18.432 MHz frequency, ±30 ppm tolerance, 18 pF load capacitance, and the 3.0 x 5.0 mm four-terminal no-lead package geometry. Verify that alternative manufacturers offer compatible footprints and electrical characteristics to ensure seamless integration without redesigning the host circuit.
