Crystals Overview

The HKC 3225S41218BMDALCDJE-CT is a surface-mount crystal oscillator operating at a fundamental frequency of 12.187 MHz. It features a load capacitance of 15 pF and an equivalent series resistance (ESR) of 100 Ohms. The component exhibits a frequency tolerance of ±15 ppm and utilizes a 4-SMD, no lead package configuration.

Crystals Feature Summary

• Provides stable oscillation at 12.187 MHz with ±15 ppm tolerance
• Designed for surface-mount integration via a 4-SMD no lead package
• Operates with a standard 15 pF load capacitance

Crystals Applications

• Clock signal generation in digital circuits
• Frequency reference sources for microcontrollers
• Timing components in communication modules

Crystals Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 100 Ohm ESR specification aligns with the oscillator circuit's stability needs. Ensure the 4-SMD no lead package dimensions are compatible with the printed circuit board layout and assembly processes to prevent mechanical or electrical mismatches during production.

Crystals Selection Notes

Select this component when a precise 12.187 MHz reference is required with moderate stability. The ±15 ppm tolerance suits general-purpose timing applications rather than high-precision synchronization. Consider the 100 Ohm ESR value for impedance matching within the specific oscillator topology. The surface-mount form factor facilitates automated assembly in compact electronic designs.

Crystals Part Context

This part belongs to the family of surface-mount crystal resonators manufactured by HKC. It serves as a passive frequency control element essential for establishing accurate clock signals in electronic systems. The designation indicates specific electrical parameters including frequency, load capacitance, and package type, distinguishing it from other variants in the manufacturer's portfolio.

Crystals Replacement Considerations

Substitute parts must match the 12.187 MHz frequency, 15 pF load capacitance, and 4-SMD no lead package. Verify that the replacement component offers equal or better frequency stability and ESR characteristics to ensure circuit reliability without modification.
