416F50012IST

Overview

The 416F50012IST is a 50 MHz fundamental mode crystal resonator manufactured by CTS-Frequency Controls. It features a frequency tolerance of ±10 ppm and stability of ±20 ppm with a series load capacitance. The component utilizes a 4-SMD, No Lead package measuring 1.60mm x 1.20mm x 0.45mm maximum height. It operates within a temperature range of -40°C to +85°C and has an equivalent series resistance (ESR) of 60 Ohms. The device complies with RoHS3 standards and holds an MSL rating of Level 1.

Feature Summary

• Fundamental mode operation for precise frequency control
• Compact surface-mount footprint suitable for automated assembly
• Wide industrial operating temperature range capability
• Compliance with environmental directives including RoHS3

Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Procurement Notes

Verify the specific suffix IST against the manufacturer's current product lifecycle status, as availability may vary. Confirm that the 4-SMD package dimensions align with the PCB footprint requirements. Ensure the 60 Ohm ESR matches the oscillator circuit design specifications. Validate compliance with project-specific environmental regulations such as RoHS3 before finalizing procurement decisions.

Selection Notes

Select this component when a 50 MHz fundamental resonance is required with tight initial tolerance. The 4-SMD form factor supports high-volume surface mount processes. Consider the -40°C to +85°C range for industrial environments. Verify that the circuit can drive the specified ESR value without excessive loading effects on the frequency stability.

Part Context

This part belongs to the CTS 416 series of miniature crystals. The series offers various load capacitance options and frequency tolerances in a standardized small outline package. The 416F50012IST specifically targets applications requiring stable 50 MHz timing in space-constrained designs.

Replacement Considerations

Direct substitutes include other 416 series variants with matching 50 MHz frequency and 4-SMD packaging. Verify equivalent ESR and temperature range compatibility. Cross-reference with other manufacturers offering identical 1.6x1.2mm footprint crystals if supply constraints exist.
