7V-32.768MAAV-T

Crystals Overview

The 7V-32.768MAAV-T is a MHz quartz crystal manufactured by TXC Corporation, designed for surface-mount applications. It operates at a fundamental frequency of 32.768 MHz with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 60 Ohms. The component features a frequency stability of ±30 ppm at 25°C and ±30 ppm across the operating temperature range of -20°C to +70°C. Housed in a compact 4-SMD, No Lead package measuring 3.2 mm x 2.5 mm with a maximum height of 0.90 mm, it utilizes a glass seal construction.

Crystals Feature Summary

• Utilizes glass seal construction for enhanced environmental durability
• Supports surface-mount installation via 4-SMD no-lead configuration
• Maintains consistent frequency stability across specified industrial temperature ranges

Crystals Applications

• Clock signal generation in digital circuits
• Timing references for microcontrollers
• Communication interface synchronization

Crystals Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to integration. Confirm that the specific ordering suffix matches the required load capacitance and tolerance specifications. Ensure the selected package variant aligns with PCB footprint constraints. Cross-reference datasheet parameters against system requirements to guarantee operational reliability within the defined temperature limits.

Crystals Selection Notes

Select this component when a precise 32.768 MHz reference is required in space-constrained designs. The 8 pF load capacitance dictates oscillator circuit design compatibility. Consider the 60 Ohm ESR value for drive level sensitivity. The -20°C to +70°C range suits general commercial electronics rather than harsh industrial environments requiring wider thermal margins.

Crystals Part Context

This part belongs to the 7V series of ceramic crystals from TXC Corporation. The series focuses on providing reliable timing solutions in small form factors suitable for modern consumer electronics. The 7V designation indicates specific manufacturing characteristics regarding the crystal blank and packaging technology used by the manufacturer.
