416F40613ALT

Crystals Overview

The CTS-Frequency Controls 416F40613ALT is a fundamental mode MHz crystal resonator operating at 40.61 MHz. It features a frequency tolerance of ±10ppm and a load capacitance of 12pF. The equivalent series resistance (ESR) is specified as 60 Ohms in primary documentation, with some sources indicating 100 Ohms. The component utilizes a 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm. It supports a temperature range of -10°C to 60°C.

Crystals Feature Summary

• Fundamental oscillation mode for stable frequency generation
• Compact surface-mount design suitable for space-constrained PCB layouts
• Low profile no-lead package construction

Crystals Applications

• Clock signal generation for microprocessors
• Timing reference for communication interfaces
• Frequency control in consumer electronics

Crystals Procurement Notes

Verify the specific ESR value (60 Ohms vs 100 Ohms) against the official manufacturer datasheet prior to procurement, as discrepancies exist between different data sources. Confirm that the -10°C to 60°C temperature range meets the operational requirements of the target application environment. Ensure the 12pF load capacitance matches the circuit design specifications to maintain the required ±10ppm frequency accuracy.

Crystals Selection Notes

Select this component when a precise 40.61 MHz timing source is required within a compact footprint. The ±10ppm tolerance offers higher precision than standard ±30ppm crystals. Consider the limited temperature range (-10°C to 60°C) and ensure it aligns with the environmental conditions. The 4-SMD package requires appropriate reflow soldering profiles compatible with no-lead components.

Crystals Part Context

This part belongs to the CTS 416 series of surface-mount crystals. The series is characterized by small form factors designed for modern electronic assemblies. The 416F40613ALT specifically targets applications requiring high-frequency stability in a minimal physical size, distinguishing it from larger through-hole or industrial-grade variants.

Crystals Replacement Considerations

The 416F40613ALR is an alternative variant within the same series offering identical electrical characteristics and package dimensions. Substitution should be verified against the specific ESR and temperature rating requirements of the original design.
