416F50022ASR

Overview

The CTS-Frequency Controls 416F50022ASR is a surface-mount MHz crystal resonator designed for precision timing applications. It operates at a fundamental frequency of 50.0000 MHz with a load capacitance specified as series. The component exhibits a frequency tolerance and stability of ±20 ppm, alongside an equivalent series resistance (ESR) of 60 Ohms. Housed in a compact 4-SMD, no-lead package measuring 1.60mm x 1.20mm with a maximum height of 0.45mm, it supports operation within a temperature range of -40°C to +85°C. This device complies with RoHS3 standards and features Moisture Sensitivity Level 1.

Feature Summary

• Fundamental mode oscillation for stable frequency generation
• Compact 4-SMD surface-mount footprint for automated assembly
• Wide industrial operating temperature range capability
• Compliance with RoHS3 environmental directives

Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Digital signal processing systems
• Consumer electronics timing references

Procurement Notes

Verify the specific load capacitance requirement against the target circuit design, as the datasheet lists this parameter as series rather than a fixed value. Confirm that the 60 Ohm ESR aligns with the oscillator circuit's drive level constraints to prevent over-driving the crystal. Ensure the PCB layout accommodates the 1.60mm x 1.20mm package dimensions and allows for proper solder joint formation on the four SMD contacts.

Selection Notes

Select this component when a 50 MHz fundamental frequency with ±20 ppm stability is required in a small form factor. The 4-SMD package suits high-density board designs. Consider the -40°C to +85°C temperature range for industrial or automotive environments. Verify compatibility with the host oscillator's input impedance and drive strength specifications before finalizing the bill of materials.

Part Context

This part belongs to the CTS 416 Series, a line of miniature surface-mount crystals. The series is characterized by its small 1.60mm x 1.20mm footprint, making it suitable for space-constrained portable and industrial devices. The 416 series generally offers fundamental mode operation with standardized electrical parameters to simplify integration into various digital timing applications.

Replacement Considerations

Direct substitutes within the same series include parts with identical frequency and package but different suffixes indicating variations in tolerance or packaging. Cross-manufacturer replacements must match the 50 MHz frequency, 60 Ohm ESR, and 1.60mm x 1.20mm SMD footprint to ensure mechanical and electrical compatibility.
