C7S-20.000-12-1520-R

Crystals Overview

The C7S-20.000-12-1520-R is a surface-mount quartz crystal manufactured by Aker Technology Corp, operating at a standard frequency of 20 MHz. It features a frequency tolerance and stability of ±15 ppm with a load capacitance of 12 pF. The component utilizes a 4-SMD, no-lead package measuring 2.0 mm in length, 1.6 mm in width, and 0.55 mm in height. It operates within a temperature range of -40°C to +85°C and includes a maximum series resistance of 45 ohms.

Crystals Feature Summary

• Provides precise timing signals via a 20 MHz fundamental frequency output
• Ensures high frequency stability with ±15 ppm tolerance specification
• Designed for compact electronic assemblies using a small surface-mount footprint

Crystals Applications

• Microcontroller clock generation circuits

Crystals Procurement Notes

Verify the specific suffix 'R' against the manufacturer's current datasheet to confirm reel packaging configuration. Ensure the load capacitance requirement matches the target circuit design specifications. Confirm that the 45 ohm series resistance aligns with the oscillator driver strength capabilities. Validate compliance with RoHS standards if required by the assembly process.

Crystals Selection Notes

Select this component when a 20 MHz reference with tight ±15 ppm stability is required. The 12 pF load capacitance must match the system's capacitive loading requirements. Consider the 45 ohm series resistance for driver compatibility. The small SMD package size is suitable for space-constrained PCB layouts requiring reliable surface-mount integration.
