416F50023ISR

Crystals Overview

The CTS-Frequency Controls 416F50023ISR is a surface-mount MHz crystal operating at a nominal frequency of 50 MHz. It features a frequency tolerance of ±20ppm and a stability of ±30ppm. The component utilizes a fundamental mode of operation with an equivalent series resistance (ESR) of 60 Ohms and a load capacitance of 8pF. Packaged in a compact 4-SMD, no-lead form factor measuring 1.60mm x 1.20mm x 0.45mm, it supports an industrial temperature range of -40°C to +85°C.

Crystals Feature Summary

• Fundamental mode quartz crystal resonator for precise timing applications
• Compact 4-SMD no-lead package suitable for automated surface mount assembly
• Industrial temperature rating ensuring reliable performance across wide thermal ranges

Crystals Applications

• Clock signal generation for microprocessors and microcontrollers
• Timing references for communication interfaces such as UART and SPI
• Frequency synthesis circuits in wireless modules
• Real-time clock oscillators requiring stable base frequencies

Crystals Procurement Notes

Verify the specific suffix 'ISR' corresponds to tape-and-reel packaging when sourcing. Confirm RoHS3 compliance and MSL level 1 status for soldering profile compatibility. Ensure the 8pF load capacitance matches the circuit design requirements. Cross-reference the manufacturer part number against distributor databases to avoid confusion with similar series variants like IAR or IST.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency is required with ±20ppm initial accuracy. The 60 Ohm ESR value must be compatible with the oscillator circuit's drive level constraints. Consider the 1.60mm x 1.20mm footprint for PCB space limitations. Verify that the ±30ppm stability over temperature meets the system's jitter and phase noise specifications.

Crystals Part Context

This part belongs to the CTS 416 Series of surface-mount crystals. The series offers various frequencies and packages optimized for high-volume manufacturing. The 416F50023ISR specifically addresses the need for standard 50 MHz timing in consumer and industrial electronics where small form factors are critical.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers include 416F50023IAR and 416F50023ITR from CTS-Frequency Controls. These alternatives share identical electrical characteristics and physical dimensions, allowing for direct pin-compatible replacement without circuit redesign.
