405I35D16M38400

Crystals Overview

The CTS-Frequency Controls part number 405I35D16M38400 is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 16.384 MHz with a frequency tolerance of ±30 ppm and a stability of ±50 ppm. The component features an equivalent series resistance (ESR) of 60 Ohms and requires a load capacitance of 18 pF. It is housed in a compact 4-SMD, No Lead package with dimensions of 5.00 mm x 3.20 mm and a maximum height of 0.85 mm. The device supports industrial temperature ranges from -40°C to +85°C and complies with RoHS3 standards.

Crystals Feature Summary

• Utilizes ceramic packaging technology to achieve reduced physical size suitable for high-density circuit board layouts.
• Operates in fundamental resonance mode to provide stable frequency generation within specified tolerance limits.
• Designed for surface-mount installation using a leadless four-terminal SMD configuration.

Crystals Applications

• Clock signal generation for microprocessors and digital logic circuits
• Frequency reference sources for communication interface modules
• Timing components in consumer electronic devices requiring precise synchronization

Crystals Procurement Notes

Verify the specific suffix 'I' indicates the extended industrial temperature range (-40°C to +85°C), as opposed to commercial variants. Confirm that the 18 pF load capacitance matches the target oscillator circuit design requirements. Ensure the 4-SMD footprint aligns with the printed circuit board land pattern specifications to guarantee proper solder joint formation and mechanical reliability during assembly processes.

Crystals Selection Notes

Select this component when a 16.384 MHz fundamental frequency is required for timing applications. The choice depends on the necessity for a 60 Ohm ESR and 18 pF load capacitance compatibility. Consider the 4-SMD form factor for space-constrained designs. Evaluate the ±30 ppm tolerance against system clock accuracy requirements. Verify that the operating environment falls within the specified temperature range for reliable performance.

Crystals Part Context

This component belongs to the CTS 405 Series of ceramic packaged crystals. The series is characterized by its small footprint and robust construction for surface-mount technology. The '405I' designation typically denotes industrial temperature grade variants within this product line, distinguishing them from commercial or automotive grades based on thermal performance specifications.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 405C35D16M38400 and 403C35D16M38400. These alternatives share identical electrical parameters and physical dimensions but may differ in temperature rating or manufacturing origin. Verify compatibility before substitution.
