402F3741XIDR

Crystals Overview

The CTS-Frequency Controls 402F3741XIDR is a surface-mount crystal resonator operating at a fundamental frequency of 37.4 MHz. It features a load capacitance of 18 pF and offers a frequency tolerance of ±10 ppm with a stability of ±15 ppm across the commercial temperature range of -40°C to +85°C. The component utilizes a 4-SMD, no-lead package measuring 2.50mm x 2.00mm x 1.00mm maximum height. It exhibits an equivalent series resistance (ESR) of 60 Ohms and is designed for base harmonic operation mode.

Crystals Feature Summary

• Compact 4-SMD no-lead surface mount package design
• Fundamental mode resonance at 37.4 MHz
• High frequency stability within specified temperature range

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• Digital signal processing circuits

Crystals Procurement Notes

Verify the specific suffix 'IDR' against the manufacturer's current datasheet to confirm package dimensions and termination style. Ensure the load capacitance requirement of the target circuit matches the 18 pF specification. Confirm that the ±10 ppm tolerance meets the system timing accuracy requirements before finalizing the bill of materials.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required in a small form factor. The 18 pF load capacitance must align with the oscillator circuit design. Consider the 60 Ohm ESR value for startup reliability. This part is suitable for applications requiring moderate stability without the need for active oscillator components.

Crystals Part Context

This crystal belongs to the 402 series from CTS-Frequency Controls, which provides various fundamental mode crystals in SMD packages. The series supports frequencies ranging from low kilohertz to high megahertz ranges. The 402F3741XIDR specifically addresses the need for precise timing in compact electronic devices where space constraints limit larger through-hole or larger SMD options.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals with identical 18 pF load capacitance and similar ESR values. Verify that any replacement maintains the same 4-SMD footprint and pin configuration. Cross-reference with CTS part numbers such as those in the 402 series having matching electrical parameters.
