402F25022IKR

Crystals Overview

The CTS-Frequency Controls 402F25022IKR is a surface-mount MHz crystal operating at a fundamental frequency of 25 MHz. It features a load capacitance of 8 pF and a frequency tolerance of ±20 ppm, with stability rated at ±20 ppm. The component exhibits an equivalent series resistance (ESR) of 100 Ohms and utilizes a 4-SMD, no-lead package measuring 2.50mm in length, 2.00mm in width, and 0.70mm in maximum height. Designed for operation between -40°C and +85°C, it complies with RoHS3 standards and holds an MSL rating of 1.

Crystals Feature Summary

• Fundamental mode oscillation capability
• Surface-mount compatible 4-SMD footprint
• Industrial temperature range support

Crystals Applications

• Microcontroller clock sources
• Communication interface timing
• General-purpose digital circuit synchronization

Crystals Procurement Notes

Verify the specific suffix IKR against the manufacturer's current datasheet to confirm pin configuration and tape-and-reel specifications. Ensure the design-in process accounts for the 8pF load capacitance requirements of the target oscillator circuit. Confirm that the 100 Ohm ESR value aligns with the driving strength limitations of the host device to prevent over-driving or failure to start.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency crystal is required in a compact 2.5x2.0mm SMD package. The 8pF load capacitance suits circuits designed for lower capacitive loading compared to 12pF or 18pF variants. Consider the ±20ppm tolerance if higher precision is not mandated by the system timing budget.

Crystals Part Context

This part belongs to the CTS 402 series of general-purpose crystals. The series offers various frequencies and packages, providing designers with standardized options for embedded systems. The 402F25022IKR specifically addresses the need for cost-effective, small-footprint timing solutions in consumer and industrial electronics where moderate stability suffices.

Crystals Replacement Considerations

Direct substitutes include parts from the same series with identical electrical parameters but different packaging suffixes, such as 402F25022IAR or 402F25022ILR, provided the mechanical footprint remains compatible.
