435F18423IKT

Crystals Overview

The CTS-Frequency Controls 435F18423IKT 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 and an equivalent series resistance (ESR) of 90 kOhms. The component supports a wide operating temperature range from -40°C to +85°C, ensuring stability in demanding environments. Packaged in a compact 2-SMD, no lead form factor measuring 2.0mm x 1.2mm, it complies with RoHS3 standards and holds an MSL rating of 1.

Crystals Feature Summary

• Provides stable low-frequency timing reference using tuning fork technology
• Designed for surface mount assembly on printed circuit boards
• Maintains performance across extended industrial temperature ranges

Crystals Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system oscillators
• Portable battery-powered devices requiring low power consumption

Crystals Procurement Notes

Verify the specific suffix 'IKT' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the 12.5 pF load capacitance matches the oscillator circuit design specifications to ensure accurate frequency generation. Check for any recent lifecycle status updates or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Crystals Selection Notes

Select this component when a compact footprint is critical for space-constrained designs. The 32.768 kHz frequency is ideal for dividing down to one-second intervals in digital systems. Ensure the PCB layout accommodates the 2.0mm x 1.2mm package dimensions and allows for proper thermal management within the specified operating temperature range.

Crystals Part Context

This part belongs to the CTS tuning fork crystal family, specialized for low-frequency applications. Unlike high-frequency AT-cut crystals, these components utilize BT-cut quartz geometry optimized for 32.768 kHz operation. They are distinct from MEMS oscillators by offering passive frequency control without internal amplification circuits.

Crystals Replacement Considerations

Direct substitutes include other 32.768 kHz tuning fork crystals with identical 12.5 pF load capacitance and compatible ESR values. Verify that alternative parts match the 2-SMD package dimensions and meet the same -40°C to +85°C temperature requirements.
