C1E-40.000-8-1550-X1-R

Crystals Overview

The C1E-40.000-8-1550-X1-R is a 40 MHz quartz crystal resonator manufactured by Aker Technology Corp. It operates in fundamental series resonance mode with a frequency tolerance of ±15 ppm at 25°C and stability over temperature of ±30 ppm across the -10 to +70 °C range. The component features an 8 pF load capacitance, 50 Ω equivalent series resistance (ESR), and 100 µW drive level. It utilizes a 4-SMD, no lead package measuring 2.0 x 1.6 x 0.6 mm.

Crystals Feature Summary

• Compact surface-mount design suitable for space-constrained applications
• High frequency stability within specified industrial temperature ranges
• RoHS compliant construction without lead content

Crystals Applications

• Ultra-wideband (UWB) communication modules
• Wireless sensor networks
• Precision timing circuits requiring stable 40 MHz reference

Crystals Procurement Notes

Verify that the specific suffix X1-R matches the required frequency tolerance and package variant. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates before finalizing procurement orders to ensure regulatory adherence.

Crystals Selection Notes

Select this component when a fundamental mode 40 MHz crystal with ±15 ppm initial tolerance is required. Ensure circuit design supports 8 pF load capacitance and 50 Ω ESR constraints. Consider thermal environment limits against the -10 to +70 °C operating specification.

Crystals Part Context

This part belongs to the C1E series of ultra-wideband crystals from Aker Technology Corp. These components are engineered for high-frequency wireless applications requiring precise timing references in compact form factors, distinguishing them from larger through-hole or parallel resonance variants.

Crystals Replacement Considerations

Direct substitutes include C1E-40.000-8-1030-A-X2-R and C1E-40.000-8-1050-A-X1-R. Verify electrical parameters such as load capacitance and ESR match before substitution.
