CS15186-12M

Overview

The NDK CS15186-12M is a surface-mount quartz crystal resonator operating at a fundamental frequency of 12 MHz. It features a load capacitance of 8 pF and a frequency tolerance of ±15 ppm. The component utilizes a 4-SMD, no-lead package with dimensions of 3.20 mm x 2.50 mm and a maximum height of 0.60 mm. It exhibits an equivalent series resistance (ESR) of 100 Ohms and supports base harmonic operation. The device is rated for a working temperature range of -10°C to 75°C and complies with RoHS3 standards.

Feature Summary

• Provides robust environmental resistance against heat, vibration, and shock, suitable for demanding applications.
• Utilizes a compact 4-SMD surface-mount package for efficient PCB integration.
• Operates in fundamental mode with stable frequency characteristics.

Applications

• Automotive electronic systems requiring high vibration resistance
• General-purpose microcontroller clock sources
• Communication modules requiring stable 12 MHz timing

Procurement Notes

Verify the specific ordering suffix matches the required datasheet version, such as STD-CSR-1, to ensure correct specifications. Confirm that the package type corresponds to the 4-SMD, no-lead configuration. Check for RoHS3 compliance status if environmental regulations apply to the final assembly. Ensure the load capacitance requirement aligns with the circuit design's 8 pF specification.

Selection Notes

Select this component when a 12 MHz fundamental frequency crystal is required with moderate stability. The 100 Ohm ESR value should be compatible with the oscillator circuit's drive level requirements. Consider the -10°C to 75°C operating range for standard commercial or automotive environments. The small form factor makes it suitable for space-constrained designs.

Part Context

This part belongs to the NX3225SA series of small surface-mount crystals from NDK. The series is designed to offer excellent durability against physical stressors like shock and vibration. It serves as a timing reference for digital circuits where size and reliability are critical factors.

Replacement Considerations

The KYOCERA AVX CX3225SB30000D0FLJCC is listed as a substitute option. Verify electrical compatibility, including frequency, load capacitance, and ESR, before substitution. Ensure the replacement package dimensions fit the existing footprint.
