C7S-22.1184-12-1520-R

Crystals Overview

The C7S-22.1184-12-1520-R is a surface-mount quartz crystal oscillator manufactured by Aker Technology Corp. It operates at a standard frequency of 22.1184 MHz with a frequency tolerance and stability of ±15 ppm. The component features a load capacitance of 12 pF and a series resistance of 30 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 5 mm in length, 3.2 mm in width, and 1 mm in height. The device is rated for an operating temperature range of -20°C to 70°C and complies with RoHS standards.

Crystals Feature Summary

• Surface-mount design for automated assembly
• High frequency stability with ±15 ppm tolerance
• RoHS compliant construction

Crystals Applications

• Clock generation for digital circuits
• Communication interface timing
• Microcontroller system oscillators

Crystals Procurement Notes

Verify the specific frequency tolerance requirement against the datasheet specification of ±15 ppm, as other variants may differ. Confirm that the 12 pF load capacitance matches the target circuit design parameters. Ensure the operating temperature range of -20°C to 70°C meets the environmental conditions of the intended application. Check for RoHS compliance requirements if restricted substances are prohibited in the final product assembly process.

Crystals Selection Notes

Select this component when a precise 22.1184 MHz reference is required for SMD applications. The ±15 ppm tolerance offers higher precision than standard ±30 ppm crystals. Consider the 12 pF load capacitance compatibility with the host oscillator circuit. The compact 3.2mm x 5.0mm footprint suits space-constrained PCB layouts. Evaluate the -20°C to 70°C temperature range against operational extremes.

Crystals Part Context

This part belongs to the C7S series of surface-mount crystals from Aker Technology Corp. The series includes various frequencies and tolerances, such as the C7S-22.1184-12-1530-X-R variant which differs in tolerance specifications. The C7S designation indicates a specific package style and mounting configuration distinct from through-hole or larger surface-mount alternatives.

Crystals Replacement Considerations

Direct substitutes include C7S-22.1184-12-1530-X-R, though it specifies a ±30 ppm tolerance rather than ±15 ppm. Other family members like C7S-22.1184-10-1530-X-M share similar physical dimensions but may have different electrical characteristics. Verify pinout and load capacitance compatibility before substitution.
