C3E-12.000-18-3030-R

Crystals Overview

The C3E-12.000-18-3030-R is a parallel fundamental quartz crystal manufactured by Aker Technology Corp. It operates at a standard frequency of 12 MHz with a frequency tolerance and stability of ±30 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 80 Ohms. Designed for surface mount applications, it utilizes a 4-pin package with dimensions of 3.2 mm in length, 2.5 mm in width, and 0.75 mm in height. The device supports an operating temperature range from -40°C to +85°C and complies with RoHS standards.

Crystals Feature Summary

• Surface mount design with four terminals for automated PCB assembly
• Parallel fundamental resonance mode for stable oscillator circuits
• RoHS compliant construction for environmental safety

Crystals Applications

• Precision timing circuits requiring 12 MHz reference
• Microcontroller clock generation systems
• Communication interface synchronization modules

Crystals Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration when ordering. Confirm that the 18 pF load capacitance matches the target circuit design requirements. Ensure the 80 Ohm ESR value is compatible with the oscillator driver strength. Check for RoHS compliance documentation if required by project specifications. Validate the 4-pin SMD footprint against the PCB layout guidelines.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency with ±30 ppm stability is required. The 18 pF load capacitance must align with the external capacitors used in the oscillator circuit. Consider the 80 Ohm ESR for drive level limitations to prevent over-driving the crystal. The -40°C to +85°C temperature range suits general commercial applications. The compact 3225 package size is suitable for space-constrained designs.

Crystals Part Context

This part belongs to the C3E series of surface mount crystals from Aker Technology Corp. The series offers various frequencies and load capacitances. The C3E designation typically denotes a 3225 package size. This specific model provides a balance of performance and cost for standard digital electronics.

Crystals Replacement Considerations

Cross-reference with other 12 MHz, 18 pF, 4-pin SMD crystals from Aker or other manufacturers. Verify pin compatibility and electrical parameters such as ESR and stability before substitution.
