C1E-20.000-10-1520-R

Crystals Overview

The C1E-20.000-10-1520-R is a passive crystal resonator manufactured by Aker Technology Corp. It operates at a fundamental frequency of 20 MHz with a frequency tolerance of ±15 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 120 Ohms. It is housed in a compact 4-SMD, No Lead package, specifically the SMD2016-4P form factor, designed for surface-mount assembly.

Crystals Feature Summary

• Provides stable 20 MHz timing reference
• Compact surface-mount footprint
• Low ESR design for efficient oscillation

Crystals Applications

• Microcontroller clock circuits
• Communication module timing
• Embedded system oscillators

Crystals Procurement Notes

Verify the specific suffix -R against the manufacturer's current datasheet to confirm RoHS compliance status and lead-free solder composition requirements. Ensure the ordering part number matches the exact load capacitance and tolerance specifications required by the target circuit design before finalizing procurement.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±15 ppm stability is required. The 10 pF load capacitance must match the oscillator circuit's external capacitors. The 120 Ohm ESR value should be compatible with the driving circuit's gain capabilities to ensure reliable startup.

Crystals Part Context

This part belongs to the C1E series of surface-mount crystals from Aker Technology Corp. These components are engineered for general-purpose timing applications where space constraints necessitate small packages like the 2016 size. They serve as primary frequency references for digital logic and communication interfaces.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals with identical 10 pF load capacitance and similar ESR values. Verify mechanical dimensions and pin compatibility. Cross-reference with Aker's own variants such as C7S-20.000-10-1520-R if package differences are acceptable.
