C16-40.000-10-1010-R

Crystals Overview

The C16-40.000-10-1010-R is a parallel fundamental quartz crystal manufactured by Aker Technology Corp. It operates at a nominal frequency of 40 MHz with a frequency tolerance of ±10 ppm at 25°C. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 60 Ohms maximum. Designed for surface mount applications, it utilizes a 4-SMD, No Lead package configuration. The device supports a standard temperature range of -10 to +70 °C and exhibits an aging rate of ±3 ppm per year.

Crystals Feature Summary

• Fundamental mode parallel resonance operation
• Surface mount 4-pin no lead package design
• RoHS compliant and lead-free construction

Crystals Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Communication module timing references

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required load capacitance and tolerance specifications. Confirm that the 4-SMD package dimensions align with the target PCB footprint. Check for RoHS compliance status if restricted substances are mandated by the end product regulations. Ensure the operating temperature range meets the environmental requirements of the final assembly.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 40 MHz applications with moderate stability needs. The 10 pF load capacitance suits circuits designed for this specific capacitive load. Consider the 60 Ohm ESR limit for oscillator drive level calculations. The standard temperature range is suitable for commercial environments rather than harsh industrial conditions requiring extended ranges.

Crystals Part Context

This part belongs to Aker Technology Corp's line of surface mount quartz crystals. It is functionally comparable to other 40 MHz SMD crystals from various manufacturers, such as the 416F40011AAR from CTS-Frequency Controls or the Q40-JXS11-10-10/10-FU-LF from Jauch Quartz. These equivalents share similar electrical parameters and package types, allowing for potential cross-referencing in design phases.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 416F40011AAR from CTS-Frequency Controls and Q40-JXS11-10-10/10-FU-LF from Jauch Quartz. Verify pinout compatibility and mechanical footprint before substitution. Electrical parameters must match within acceptable tolerances for the specific oscillator circuit design.
