416F50023ATR

Overview

The CTS-Frequency Controls 416F50023ATR is a 50 MHz fundamental mode crystal resonator designed for surface-mount applications. It features a frequency tolerance of ±20 ppm and a stability of ±30 ppm over the operating temperature range of -40°C to +85°C. The component utilizes an 8 pF load capacitance and exhibits an equivalent series resistance (ESR) of 60 Ohms. Housed in a compact 4-SMD, No Lead package with dimensions of 1.60mm x 1.20mm x 0.45mm maximum height, it is supplied in tape and reel packaging for automated assembly processes.

Feature Summary

• Fundamental mode operation ensures precise frequency generation at 50 MHz
• Compact 4-SMD no-lead footprint facilitates high-density PCB layouts
• Wide operating temperature range supports diverse environmental conditions

Applications

• High-speed digital clock signal generation
• Microcontroller and processor timing references
• Communication interface synchronization circuits

Procurement Notes

Verify that the specific suffix 'ATR' corresponds to the tape and reel packaging format required for your manufacturing line. Confirm that the 8 pF load capacitance matches the oscillator circuit design specifications. Ensure the ±20 ppm frequency tolerance meets the system's jitter and phase noise requirements. Cross-reference the RoHS compliance status with current regulatory standards for your target market.

Selection Notes

Select this component when a fundamental mode crystal is required for 50 MHz applications with strict size constraints. The 4-SMD no-lead package offers superior solder joint reliability compared to traditional leaded packages. Consider the 60 Ohm ESR value to ensure adequate drive level compatibility with the host oscillator circuit. The wide temperature stability makes it suitable for industrial or automotive environments where thermal variations are significant.

Part Context

This part belongs to the CTS 416 Series, which focuses on small-footprint surface-mount crystals. The series provides various frequency options and stability codes to support modern electronics miniaturization trends. The 416F50023ATR specifically addresses the demand for reliable timing solutions in space-constrained devices requiring stable 50 MHz reference clocks.

Replacement Considerations

The 416F50023IAR is listed as a similar alternative within the same manufacturer lineup. Verify mechanical compatibility and electrical parameter equivalence before substitution. Other variants in the 416 series may offer different load capacitances or stability ratings.
