402F25022IJR

Crystals Overview

The CTS-Frequency Controls 402F25022IJR is a surface-mount quartz crystal resonator operating at a fundamental frequency of 25 MHz. It features a load capacitance of 9 pF and a frequency stability of ±20 ppm. The component exhibits an equivalent series resistance (ESR) of 100 Ohms and supports base harmonic operation. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.00 mm x 1.60 mm and a maximum height of 0.55 mm. The device operates within a temperature range of -40°C to +85°C and complies with RoHS3 standards.

Crystals Feature Summary

• Provides precise timing signals through fundamental mode quartz resonance
• Ensures stable oscillation with low equivalent series resistance
• Supports automated assembly via standard surface-mount packaging

Crystals Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Precision measurement instrumentation

Crystals Procurement Notes

Verify the specific suffix IJR against official CTS documentation to confirm lead frame material and termination plating specifications. Ensure compatibility with reflow soldering profiles defined for the 4-SMD package. Confirm that the 9 pF load capacitance matches the oscillator circuit design requirements before integration.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency is required with strict ±20 ppm stability limits. The 9 pF load capacitance distinguishes it from other variants in the 402 series, such as those requiring 12 pF. Consider the 100 Ohm ESR value for driving level sensitivity analysis in the target application circuit.

Crystals Part Context

This part belongs to the CTS 402 Series of miniature crystals designed for high-volume surface-mount applications. The series offers various frequencies and load capacitances within a standardized 2.00 x 1.60 mm footprint. The 402F25022IJR specifically addresses needs for 25 MHz timing with lower load capacitance requirements compared to standard 12 pF variants.

Crystals Replacement Considerations

Direct substitutes include parts with identical electrical parameters and package dimensions. Verify that any replacement maintains the 9 pF load capacitance and 100 Ohm ESR to ensure circuit stability without modification.
