402F38412ILT

Crystals Overview

The 402F38412ILT is a surface-mount quartz crystal manufactured by CTS-Frequency Controls. It operates at a fundamental frequency of 38.4 MHz with a load capacitance of 12 pF and a frequency tolerance of ±10 ppm. The component features an equivalent series resistance (ESR) of 60 Ohms and is housed in a 4-SMD, no-lead package measuring 2.00 mm x 1.60 mm x 0.55 mm. It supports base harmonic operation within a temperature range of -20°C to +70°C.

Crystals Feature Summary

• Fundamental mode quartz crystal resonator
• Compact 4-SMD surface mount footprint
• Automotive-grade reliability options available in series

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• Embedded system oscillators

Crystals Procurement Notes

Verify the specific suffix requirements for your design, as packaging variants like ILT indicate tape and reel configuration. Confirm that the operating temperature range of -20°C to +70°C meets your environmental specifications. Cross-reference the ESR value of 60 Ohms with your oscillator circuit design to ensure proper startup conditions. Check current availability status as supply levels may fluctuate.

Crystals Selection Notes

Select this component when a 38.4 MHz fundamental frequency is required with tight ±10 ppm stability. Ensure the PCB layout accommodates the 2.00mm x 1.60mm SMD package dimensions. Compare against higher stability variants if tighter tolerances are needed, or consider the CA70 series if an active oscillator output is preferred over a passive crystal.

Crystals Part Context

This part belongs to the 402 series of crystals from CTS-Frequency Controls, designed for general-purpose timing applications. It shares the same physical footprint and basic electrical characteristics with other frequencies in the series, such as the 402F19222ILT and 402F54022ILT, allowing for potential design flexibility across different clock speeds.

Crystals Replacement Considerations

Direct substitutes include 402F38412ILR and 402F38412IAR. Parameter-equivalent alternatives may exist within the same manufacturer's lineup. Verify that any replacement matches the 12 pF load capacitance and 60 Ohm ESR specifications exactly.
