402F38412ILR

Crystals Overview

The CTS-Frequency Controls 402F38412ILR is a surface-mount MHz crystal designed for precision timing applications. It operates at a fundamental frequency of 38.4 MHz with a frequency stability and tolerance of ±10ppm. The component features a load capacitance of 12pF and an equivalent series resistance (ESR) of 60 Ohms. Packaged in a compact 4-SMD, no-lead form factor measuring 2.00mm x 1.60mm with a maximum height of 0.55mm, it supports operation within a temperature range of -40°C to 85°C.

Crystals Feature Summary

• Provides high-frequency stability with ±10ppm tolerance for precise clock generation.
• Utilizes a low-profile 4-SMD no-lead package suitable for automated surface-mount assembly.
• Operates reliably across extended industrial temperature ranges from -40°C to 85°C.

Crystals Applications

• Precision clock signal generation for microprocessors and digital logic circuits
• Timing references for communication interfaces requiring stable baud rates
• Embedded systems and industrial control boards needing compact oscillators

Crystals Procurement Notes

Verify the specific suffix 'ILR' matches the required tape-and-reel packaging configuration. Confirm that the ±10ppm stability requirement aligns with system timing budgets. Ensure PCB land patterns accommodate the 2.00mm x 1.60mm footprint and 0.55mm height constraints. Cross-reference the ESR value of 60 Ohms with oscillator circuit design specifications to guarantee proper startup and sustainment.

Crystals Selection Notes

Select this component when strict frequency accuracy is critical compared to standard ±20ppm crystals. The 12pF load capacitance must match the host circuit's external capacitors. Consider the 4-SMD package size if board space is limited. Verify compatibility with the operating voltage and thermal environment of the target application before finalizing the bill of materials.

Crystals Part Context

This part belongs to the 402 Series of MHz crystals from CTS-Frequency Controls. The series offers various frequencies and stability grades in standardized SMD packages. The 402F38412ILR specifically addresses needs for higher precision timing than basic consumer-grade crystals, fitting into the industrial and professional electronics segment where reliability and accuracy are prioritized over minimal cost.

Crystals Replacement Considerations

Direct substitutes include parts with identical electrical parameters and package dimensions. Verify that any replacement maintains the 38.4 MHz frequency, 12pF load capacitance, and ±10ppm stability. Ensure the alternative component supports the same 4-SMD no-lead footprint and temperature range to maintain mechanical and thermal compatibility.
