C3E-20.000-12-1520-R

Crystals Overview

The C3E-20.000-12-1520-R is a surface-mount quartz crystal resonator manufactured by Aker Technology Corp. It operates at a fundamental frequency of 20 MHz with a nominal load capacitance of 12 pF. The component exhibits a normal temperature frequency tolerance of ±15 ppm and an equivalent series resistance (ESR) of 100 Ω. Designed for commercial applications, it supports an operating temperature range from -20°C to +70°C. The device utilizes a 4-SMD, no-lead package configuration, specifically the SMD3225 form factor, ensuring compatibility with standard automated assembly processes.

Crystals Feature Summary

• Surface-mount quartz crystal resonator designed for commercial-grade timing applications
• Stable frequency performance with ±15 ppm tolerance at normal temperature
• Compact 4-SMD no-lead package suitable for space-constrained PCB layouts

Crystals Applications

• General-purpose digital circuit timing references
• Microcontroller clock sources in consumer electronics
• Communication interface synchronization modules

Crystals Procurement Notes

Verify the complete part number including the suffix '-R' to ensure compliance with RoHS standards and reel packaging specifications. Confirm that the required load capacitance matches the oscillator circuit design, as mismatched capacitance values will result in frequency deviation outside the specified ±15 ppm tolerance. Ensure the operating environment remains within the -20°C to +70°C range to maintain guaranteed performance characteristics.

Crystals Selection Notes

Select this component when a 20 MHz reference signal is required for commercial-grade applications without automotive qualification requirements. The 12 pF load capacitance specification must align with the host oscillator circuit's input capacitance to achieve accurate frequency output. Consider the 100 Ω ESR value when evaluating drive level sensitivity and power consumption constraints within the target system design.

Crystals Part Context

This model belongs to the C3E series of surface-mount crystals from Aker Technology Corp. The series offers various frequency options in standardized SMD packages. Unlike the AECQ-200 qualified products mentioned in corporate capabilities, this specific part is designated for general commercial use rather than automotive or high-reliability industrial sectors, reflecting its standard temperature range and tolerance specifications.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' 20 MHz crystals with identical 12 pF load capacitance, ±15 ppm tolerance, and 4-SMD 3225 package dimensions. Verify that alternative components meet the same 100 Ω ESR requirement and operate within the -20°C to +70°C range to ensure functional equivalence in existing designs.
