435F286X3IDT

Crystals Overview

The CTS-Frequency Controls 435F286X3IDT is a surface-mount tuning fork crystal designed for precise timing applications. It operates at a fundamental frequency of 32.768 kHz with a load capacitance of 12.5 pF. The component features an equivalent series resistance (ESR) of 90 kOhms and supports a wide operating temperature range from -40°C to +85°C. Packaged in a compact 2-SMD configuration measuring 5.0mm x 3.2mm, it ensures reliable performance in space-constrained designs while maintaining high stability.

Crystals Feature Summary

Utilizes tuning fork architecture for low power consumption and stable oscillation
Designed for surface mount integration to support automated PCB assembly processes
Operates reliably across extended industrial temperature ranges

Crystals Applications

Real-time clock circuits in embedded systems
Microcontroller system clocks
Portable battery-powered devices requiring low current draw

Crystals Procurement Notes

Verify the specific suffix IDT corresponds to the required tape and reel packaging format before ordering. Confirm that the 12.5 pF load capacitance matches the oscillator circuit design requirements. Ensure the 90 kOhm ESR is compatible with the host controller's drive level specifications to prevent overdriving the crystal element during operation.

Crystals Selection Notes

Select this component when a standard HC-49 through-hole crystal is unsuitable due to board space limitations. The 5.0mm x 3.2mm footprint offers a significant size reduction compared to traditional packages. Consider the higher ESR value typical of tuning fork crystals when designing the feedback loop impedance to ensure proper startup conditions.

Crystals Part Context

This part belongs to the 435F series of surface-mount tuning fork crystals manufactured by CTS-Frequency Controls. These components are engineered as direct replacements for legacy through-hole 32.768 kHz crystals in modern consumer electronics. The series emphasizes miniaturization while maintaining the accuracy required for timekeeping functions in digital interfaces.
