402WF25012IKR

Crystals Overview

The CTS-Frequency Controls 402WF25012IKR is a fundamental mode quartz crystal resonator designed for surface-mount applications. It operates at a nominal frequency of 25 MHz with a frequency tolerance of ±10 ppm and stability of ±15 ppm. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 4-SMD, No Lead package with dimensions of 2.00 mm in length, 1.60 mm in width, and a maximum seated height of 0.079 inches (2.00 mm). The device supports a wide operating temperature range from -40°C to +85°C.

Crystals Feature Summary

• Fundamental oscillation mode operation for stable frequency generation
• Surface-mount design compatible with automated assembly processes
• Wide industrial temperature rating for diverse environmental conditions

Crystals Applications

• Microcontroller clock sources
• Communication module timing references
• Industrial control system oscillators

Crystals Procurement Notes

Verify the specific package dimensions against the target PCB footprint, as this model measures 2.00mm x 1.60mm, which differs from standard 1612 packages. Confirm that the circuit design accommodates the 80 Ohm ESR value to ensure proper oscillator startup and stability. Ensure the selected variant matches the required RoHS compliance standards for the intended market.

Crystals Selection Notes

Select this component when a 25 MHz fundamental crystal is required with an 8 pF load capacitance. The 402W series offers a larger footprint than the 416W series, which may benefit certain layout constraints. Verify that the application environment falls within the -40°C to +85°C operational range. Consider the 80 Ohm ESR specification when designing the oscillator circuit feedback network.

Crystals Part Context

This part belongs to the CTS 402W series of surface-mount crystals. Unlike the smaller 416W series, the 402W series provides a 2.00mm x 1.60mm footprint. It shares the same 25 MHz frequency and 8 pF load capacitance profile but differs in physical size and ESR characteristics compared to other variants in the manufacturer's portfolio.

Crystals Replacement Considerations

The LFXTAL081609 by IQD Frequency Products is documented as a parameter-equivalent substitute. Verify mechanical fitment due to potential dimensional differences between the 402W and alternative series packages.
