416F50012IAT

Overview

The CTS-Frequency Controls 416F50012IAT is a surface-mount MHz crystal operating at a nominal frequency of 40.61 MHz. It features a load capacitance of 10pF and a frequency tolerance of ±10ppm, with a stability of ±20ppm. The component utilizes a 4-SMD, No Lead package measuring 1.60mm x 1.20mm x 0.45mm. It exhibits an equivalent series resistance (ESR) of 60 Ohms and operates in fundamental mode across a temperature range of -40°C to 85°C.

Feature Summary

• Compact 4-SMD no-lead surface mount design for automated assembly
• Fundamental mode operation ensuring stable oscillation
• Wide industrial temperature rating for harsh environments

Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Procurement Notes

Verify the specific suffix 'IAT' against current manufacturer documentation, as this part number may be discontinued or restricted. Confirm that the 40.61 MHz frequency and 10pF load capacitance match the target circuit requirements before procurement. Check for active replacement options if availability is limited.

Selection Notes

Select this component when a precise 40.61 MHz reference is required in a compact form factor. Ensure the application circuit supports a 10pF load capacitance to maintain the specified ±10ppm tolerance. Consider the 60 Ohm ESR value for oscillator drive level calculations to prevent overdriving the crystal.

Part Context

This component belongs to the CTS 416 series of miniature crystals. The series is characterized by small footprint dimensions suitable for space-constrained printed circuit boards. The 416F50012IAT specifically targets applications requiring high-frequency stability in a standard SMD package format.

Replacement Considerations

Public confirmed substitutes include 416F40612IKR and 416F40612ILR from CTS-Frequency Controls.
