CX532Z-A2B3C5-70-50.0D18

Crystals Overview

The CX532Z-A2B3C5-70-50.0D18 is a parallel fundamental quartz crystal from the Cardinal Components CX532 series, designed for surface mount applications. It operates at a nominal frequency of 50 MHz with a load capacitance of 18 pF and an equivalent series resistance of 70 Ohms. The component features a frequency stability of ±30 ppm and a tolerance of ±20 ppm. It supports an operating temperature range of -40°C to +85°C and utilizes a 2-SMD no-lead ceramic package measuring 5.00 mm x 3.20 mm.

Crystals Feature Summary

• Surface mount ceramic construction in a compact 2-SMD no-lead package
• Parallel fundamental oscillation mode for stable clock generation
• Tape and reel packaging configuration for automated assembly

Crystals Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Digital communication interface timing

Crystals Procurement Notes

Verify that the specified 70 Ohm ESR matches the circuit design requirements, as this value differs from standard lower-resistance alternatives. Confirm the 18 pF load capacitance aligns with the host oscillator's external capacitor values to ensure accurate frequency performance. Ensure the -40°C to +85°C industrial temperature rating satisfies the operational environment constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency is required with specific impedance matching. The 70 Ohm ESR necessitates careful driver strength evaluation within the oscillator circuit. The 18 pF load capacitance is standard but must be verified against the PCB layout. Consider the tape and reel format for high-volume production lines requiring automated placement capabilities.
