7V-32.000MDDV-T

Crystals Overview

The 7V-32.000MDDV-T is a 32 MHz fundamental mode quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It features a compact 4-SMD, No Lead package with dimensions of 1.6 mm x 1.2 mm and a maximum height of 0.50 mm. The component offers a frequency stability of ±20 ppm at both 25°C and across the -20°C to +70°C operating range. It utilizes an 8 pF load capacitance and exhibits a typical equivalent series resistance (ESR) of 60 Ohms. This device is RoHS compliant and suitable for general electronic timing circuits requiring precise frequency control.

Crystals Feature Summary

• Compact 1.6x1.2 mm surface-mount footprint for space-constrained designs
• High frequency stability of ±20 ppm across specified temperature ranges
• Fundamental oscillation mode ensuring low phase noise performance
• RoHS compliant construction for environmentally safe integration

Crystals Applications

• General-purpose digital circuit timing references
• Microcontroller clock sources
• Consumer electronics internal synchronization
• Industrial control system oscillators

Crystals Procurement Notes

Verify the specific package dimensions against the official datasheet to ensure compatibility with PCB footprints, as the 1.6x1.2 mm form factor differs from standard 3225 sizes. Confirm that the 8 pF load capacitance matches the oscillator circuit requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the ±20 ppm stability meets the system's timing accuracy needs.

Crystals Selection Notes

Select this component when a small form factor is critical for the design. The ±20 ppm stability is suitable for applications where moderate precision is required. Compare against the 7V-32.000MAAV-T if a wider temperature range (-40°C to +85°C) or different load capacitance is needed. Consider the ESR value of 60 Ohms to ensure it falls within the oscillator driver's capability. Evaluate cost-effectiveness against alternative crystals in the same size category.

Crystals Part Context

This part belongs to the 7V series of ceramic quartz crystals from TXC Corporation. The series is characterized by its small SMD packages and reliability for mass-produced electronics. The 7V series covers various frequencies and stability grades, with the MDDV suffix indicating specific tolerance and temperature characteristics. It serves as a standard timing element in modern consumer and industrial hardware.

Crystals Replacement Considerations

The 7V-32.000MAAV-T is a documented parameter-equivalent substitute offering similar electrical characteristics but potentially different temperature ranges or packaging options. Verify pinout and mechanical dimensions before substitution.
