402F50033CKR

Crystals Overview

The CTS-Frequency Controls 402F50033CKR is a 50 MHz fundamental mode crystal resonator designed for surface-mount applications. It features a frequency stability of ±30 ppm and an equivalent series resistance (ESR) of 60 Ohms. The component operates within a temperature range of -20°C to +70°C and utilizes an 8 pF load capacitance. Housed in a compact 4-SMD, no-lead package measuring 1.6 mm x 1.2 mm with a maximum height of 0.45 mm, it supports automated assembly processes.

Crystals Feature Summary

• Fundamental mode operation ensures stable oscillation at the specified frequency.
• Compact surface-mount footprint facilitates high-density PCB layout.
• Low equivalent series resistance supports efficient circuit drive levels.

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Digital signal processing circuits

Crystals Procurement Notes

Verify the specific suffix 'CKR' against the manufacturer's current datasheet to confirm package dimensions and termination style. Ensure the operating temperature range of -20°C to +70°C aligns with the target application environment. Cross-reference the ESR value of 60 Ohms with the oscillator circuit design requirements to prevent startup failures or excessive power consumption.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency is required with moderate stability. The 8 pF load capacitance must match the oscillator circuit's external capacitors. Consider the -20°C to +70°C range; if wider industrial temperatures are needed, verify alternative part numbers from the same series that support -40°C to +85°C operation.
