TF161V32K7680R

Crystals Overview

TF161V32K7680R is a surface-mount tuning fork crystal manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 32.768 kHz with a frequency tolerance of ±10 ppm. The component features a load capacitance of 7 pF and an equivalent series resistance (ESR) of 90 kOhms maximum. Designed for low-power applications, it utilizes a 2-SMD, no-lead package with dimensions of 5.00 mm in length and 3.20 mm in width.

Crystals Feature Summary

• Utilizes a tuning fork resonator structure optimized for precise timekeeping applications
• Features a compact surface-mount footprint suitable for space-constrained PCB layouts
• Provides high frequency stability with tight tolerance specifications

Crystals Applications

• Real-time clock circuits in portable electronics
• Microcontroller system timing references
• Low-power embedded devices requiring accurate timebase generation

Crystals Procurement Notes

Verify the specific suffix 'R' indicates the required reel packaging configuration when ordering. Confirm that the 7 pF load capacitance matches the oscillator circuit design requirements. Ensure the 90 kOhm ESR limit is compatible with the driving circuit to prevent overdriving the crystal. Check RoHS compliance status against current project environmental regulations before finalizing procurement.

Crystals Selection Notes

Select this component when a 32.768 kHz reference with ±10 ppm accuracy is required. The 7 pF load capacitance dictates compatibility with specific oscillator topologies. Consider the 90 kOhm ESR for drive level sensitivity. The 2-SMD package size influences board space allocation compared to larger through-hole alternatives.

Crystals Part Context

This part belongs to the CTS-Frequency Controls crystal lineup, distinct from their TC series oscillators. While similar in frequency to other 32.768 kHz components, it lacks integrated CMOS output stages found in XO parts. It serves as a passive resonator element rather than an active signal generator.
