416F50022ATR

Overview

The CTS-Frequency Controls 416F50022ATR is a 50.0000 MHz fundamental mode crystal resonator designed for surface mount applications. It features a frequency tolerance and stability of ±20ppm with a load capacitance of 6pF. The component operates within a temperature range of -20°C to +70°C and exhibits an equivalent series resistance (ESR) of 60 Ohms maximum. Housed in a compact 4-SMD, No Lead package measuring 1.60mm x 1.20mm with a maximum height of 0.45mm, it supports automated assembly processes.

Feature Summary

• Fundamental mode operation ensures stable oscillation characteristics for precise timing requirements.
• Compact 4-SMD no-lead footprint facilitates efficient surface mount placement on printed circuit boards.
• Compliant with RoHS3 directives, supporting environmentally conscious manufacturing standards.

Applications

• Microcontroller clock sources requiring 50 MHz reference frequencies
• Communication modules utilizing standard crystal oscillators
• Consumer electronics with space-constrained surface mount designs

Procurement Notes

Verify the specific suffix 'ATR' corresponds to the required tape and reel packaging configuration for automated insertion equipment. Confirm that the 6pF load capacitance aligns with the host circuit's oscillator design specifications. Ensure the -20°C to +70°C operating temperature range meets the environmental conditions of the final application. Cross-reference the 60 Ohm ESR limit with system impedance requirements to guarantee reliable startup.

Selection Notes

Select this component when a 50 MHz fundamental frequency with ±20ppm stability is required in a small SMD form factor. The 6pF load capacitance dictates compatibility with specific oscillator circuits; mismatched capacitance may affect frequency accuracy. Consider the industrial temperature range limits if the application involves extreme thermal environments. The no-lead package design aids in lead-free soldering processes compliant with modern environmental regulations.

Part Context

This part belongs to the CTS 416 Series of general-purpose crystals, characterized by their small 1.6x1.2mm footprint. The series offers various load capacitances and frequency options tailored for high-volume consumer and industrial electronics. The 416F50022ATR specifically targets applications needing a 50 MHz reference in a compact, surface-mountable package suitable for dense PCB layouts.

Replacement Considerations

Direct parameter-equivalent substitutes include 416F50022CAR and 416F50022CLT from CTS-Frequency Controls. Verify that alternative parts match the 6pF load capacitance and 60 Ohm ESR specifications. Ensure replacement components maintain the same 4-SMD no-lead package dimensions for mechanical compatibility.
