402F38433CLT

Crystals Overview

The 402F38433CLT is a surface-mount MHz crystal manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 38.4 MHz with a frequency stability and tolerance of ±30ppm. The component requires a load capacitance of 12pF and exhibits an equivalent series resistance (ESR) of 60 Ohms. Designed for base harmonic operation, it functions within a temperature range of -20°C to +70°C. The device utilizes a compact 4-SMD, no-lead package measuring 3.2mm in length, 1.6mm in width, and 0.55mm in maximum height.

Crystals Feature Summary

• Provides stable 38.4 MHz timing signals via fundamental resonance mode
• Features low profile surface-mount construction for automated assembly
• Supports standard 12pF load capacitance requirements

Crystals Applications

• General purpose clock generation for digital circuits
• Timing references for microcontroller systems
• Synchronization sources for communication interfaces

Crystals Procurement Notes

This component is officially discontinued at Digi-Key and is not available for new orders or back-ordering. Procurement must rely on existing stock from secondary distributors or alternative sources. Verify the specific manufacturing date code and authenticity when sourcing from non-original channels, as availability is limited and supply chain continuity cannot be guaranteed through primary manufacturers.

Crystals Selection Notes

Engineers should evaluate the ±30ppm frequency stability against system timing requirements before implementation. The specified 12pF load capacitance must match the oscillator circuit design to ensure accurate frequency performance. Consider the -20°C to +70°C operating range to confirm suitability for the intended environmental conditions. Due to discontinuation status, identifying a direct replacement with identical electrical parameters and package dimensions is recommended for future designs.

Crystals Part Context

The 402F38433CLT belongs to the 402 Series of MHz crystals produced by CTS-Frequency Controls. This series focuses on small-footprint surface-mount components suitable for space-constrained electronic applications. The part represents a standard fundamental mode crystal designed for general-purpose timing needs rather than specialized high-stability or wide-temperature industrial automotive grades found in other product lines.

Crystals Replacement Considerations

CAUTION: This part is discontinued. No direct parameter-equivalent substitutes are listed in official distributor records. Designers should select alternative crystals with matching 38.4MHz frequency, 12pF load capacitance, 4-SMD (3.2x1.6mm) package, and ±30ppm stability.
