CC7V-T1A-32.768KHZ-7PF-10PPM-TA-QC

Crystals Overview

The CC7V-T1A-32.768KHZ-7PF-10PPM-TA-QC is a surface-mount tuning fork quartz crystal manufactured by Micro Crystal AG. It operates at a standard frequency of 32.768 kHz with a load capacitance of 7 pF and a frequency tolerance of ±10 ppm at 25°C. The component utilizes a hermetically sealed ceramic package with a metal lid, measuring 3.2 mm in length, 1.5 mm in width, and 0.9 mm in height. It supports a base mode operation within an operating temperature range of -40°C to +85°C.

Crystals Feature Summary

• Hermetically sealed ceramic construction with a metal lid for environmental protection
• Tuning fork design optimized for low-frequency timing applications
• Surface-mount form factor suitable for compact PCB layouts

Crystals Applications

• Real-time clock circuits in portable electronics
• Low-power IoT sensor nodes
• Industrial metering devices requiring stable timekeeping

Crystals Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure the load capacitance and tolerance match the circuit requirements. Confirm that the TA temperature grade aligns with the operational environment limits. Cross-reference the package dimensions with the board layout constraints to ensure proper fitment during assembly.

Crystals Selection Notes

Select this component when a tighter frequency tolerance than the standard ±20 ppm is required for accurate long-term timekeeping. Ensure the host MCU RTC circuit can support the specified load capacitance without excessive external matching components. Consider the thermal profile compatibility if the application involves high-temperature soldering processes.

Crystals Part Context

This part belongs to the CC7V-T1A series, which represents Micro Crystal's line of miniature tuning fork crystals. The series is characterized by its small footprint and robust sealing technology, designed to provide reliable performance in space-constrained consumer and industrial applications where precise frequency generation is critical.

Crystals Replacement Considerations

Direct substitutes include other CC7V-T1A variants with different load capacitances or tolerances, such as the 9pF or 12.5pF versions, provided the electrical parameters are compatible with the existing design.
