402F25033CKR

Crystals Overview

The CTS-Frequency Controls 402F25033CKR is a surface-mount crystal resonator operating at a fundamental frequency of 25 MHz. It features a frequency stability and tolerance of ±30 ppm, with a load capacitance of 8 pF and an equivalent series resistance (ESR) of 100 Ohms. The component utilizes a 4-SMD, no-lead package measuring 1.60 mm in length, 1.20 mm in width, and 0.45 mm in maximum height. Designed for base harmonic operation, it supports a wide operating temperature range from -40°C to +85°C. The device complies with RoHS3 standards and holds a Moisture Sensitivity Level (MSL) rating of 1, indicating unlimited exposure to ambient conditions.

Crystals Feature Summary

Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct load capacitance and tolerance specifications. Confirm that the 4-SMD package dimensions align with the target PCB land pattern. Check current product status as distribution listings may indicate discontinuation or limited availability despite active manufacturing designations.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required rather than an overtone variant. Ensure the circuit design accommodates the specified 8 pF load capacitance to maintain the stated ±30 ppm accuracy. Consider the physical size constraints of the 1.60 x 1.20 mm package during layout planning. Verify that the application environment remains within the -40°C to +85°C operational limits.

Crystals Part Context

This part belongs to the 402 series of surface-mount crystals from CTS-Frequency Controls. The series offers various frequency options and package sizes optimized for consumer and industrial electronics. The 402F25033CKR specifically addresses the common need for 25 MHz timing in compact SMD designs.

Crystals Replacement Considerations

Direct parameter-equivalent replacements are not explicitly confirmed in public documentation. Substitution requires verifying identical frequency, load capacitance, ESR, and package dimensions. Cross-reference with other manufacturers' 25 MHz 4-SMD crystals ensuring matching electrical characteristics.
