416F50025IST

Crystals Overview

The 416F50025IST is a 50 MHz fundamental mode crystal resonator manufactured by CTS-Frequency Controls. It features a frequency tolerance of ±20ppm and stability of ±30ppm. The component operates within a temperature range of -40°C to +85°C and utilizes a 12pF load capacitance with an equivalent series resistance (ESR) of 60 Ohms. It is housed in a compact 4-SMD, no-lead package measuring 1.60mm x 1.20mm x 0.45mm maximum height. This surface-mount device is designed for precision timing applications requiring high reliability.

Crystals Feature Summary

• Fundamental mode operation ensures stable oscillation characteristics
• Compact 4-SMD no-lead footprint facilitates automated surface-mount assembly
• Wide industrial operating temperature range supports diverse environmental conditions

Crystals Applications

• Precision clock generation for microprocessors and microcontrollers
• Timing references for communication interfaces such as UART and SPI

Crystals Procurement Notes

Verify the specific suffix IST against official CTS documentation to confirm the extended temperature rating and RoHS compliance status. Ensure that the required load capacitance matches the circuit design specifications. Cross-reference the ESR value with oscillator circuit requirements to guarantee startup reliability. Confirm package dimensions align with PCB layout constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 50 MHz fundamental crystal with ±20ppm initial tolerance is required. The -40°C to +85°C temperature range makes it suitable for industrial applications. Consider the 60 Ohm ESR and 12pF load capacitance when designing the oscillator circuit. The small 1.60mm x 1.20mm package is ideal for space-constrained designs compared to larger through-hole alternatives.
