SXTHM218BB174-26.000M

Crystals Overview

The SXTHM218BB174-26.000M is a surface-mount MHz crystal manufactured by Suntsu Electronics, Inc. It operates at a nominal frequency of 26.000MHz with a load capacitance of 18pF. The component exhibits a frequency stability of ±30ppm and a tolerance of ±25ppm. Equivalent series resistance (ESR) is specified at 30 Ohms for this variant, while the SXT21418CB27-26.000M counterpart lists 100 Ohms. Operating temperature ranges vary from -20°C to 70°C in some listings, whereas others indicate -40°C to +85°C. The package dimensions are 0.524 inches in length and 0.197 inches in width.

Crystals Feature Summary

• Surface-mount configuration for automated assembly
• Base harmonic operation mode
• RoHS3 compliant construction

Crystals Applications

• General electronic circuit timing
• Microcontroller clock sources
• Communication device oscillators

Crystals Procurement Notes

Verify the specific ESR value and operating temperature range against the official datasheet, as documentation indicates discrepancies between 30 Ohms/100 Ohms and -20°C/+70°C versus -40°C/+85°C. Confirm package dimensions match the 0.524" L x 0.197" W specification. Ensure the supplier provides the correct RoHS3 compliance documentation for regulatory adherence.

Crystals Selection Notes

Select this component when a 26MHz surface-mount crystal with 18pF load capacitance is required. Consider the ±30ppm stability requirement for timing accuracy. Evaluate the thermal environment to determine if the -20°C to 70°C or -40°C to 85°C rating is necessary. Compare ESR specifications of 30 Ohms versus 100 Ohms based on oscillator circuit design constraints.

Crystals Part Context

This part belongs to the Suntsu Electronics crystal family, sharing characteristics with models like SXTHM218BB484-26.000M and SXTHM218BB164-26.000M. These components typically utilize similar packaging and electrical parameters, differing primarily in frequency or specific suffix designations. The SXTHM218BB174-26.000M represents a standard 26MHz option within this series.

Crystals Replacement Considerations

SXT21418CB27-26.000M is listed as a related model but differs in ESR (100 Ohms vs 30 Ohms) and potentially temperature range. Verify circuit compatibility before substitution due to these electrical differences.
