SXTHM218ED174-26.000M

Crystals Overview

The SXTHM218ED174-26.000M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 26 MHz with a load capacitance of 18 pF. The component exhibits a frequency stability of ±15 ppm and an equivalent series resistance (ESR) of 30 Ohms. Designed for base mode operation, it supports a commercial operating temperature range from -20°C to +70°C. The device utilizes a 4-SMD, no-lead package configuration suitable for automated assembly processes.

Crystals Feature Summary

• Provides precise timing reference with ±15 ppm frequency stability
• Utilizes low ESR design for efficient circuit integration
• Supports standard surface-mount mounting techniques

Crystals Applications

• Microcontroller clock sources
• Communication module timing circuits
• Consumer electronics control systems

Crystals Procurement Notes

Verify the specific suffix designation against official Suntsu documentation to ensure compatibility with required tolerance and temperature specifications. Confirm that the 4-SMD package dimensions align with the target PCB footprint. Request updated datasheets directly from the manufacturer or authorized distributors to validate current production status and electrical parameter consistency before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 26 MHz fundamental frequency with ±15 ppm stability is required for space-constrained designs. Ensure the application environment remains within the -20°C to +70°C operational range. Compare the 30 Ohm ESR against the oscillator circuit requirements to guarantee reliable startup and sustained oscillation without additional external components.

Crystals Part Context

This part belongs to the Suntsu SMD crystal series, designed for general-purpose timing applications. It differs from through-hole variants like HC-49/US packages by offering a compact surface-mount form factor. The model specifically targets cost-sensitive consumer and industrial electronics requiring stable clock signals in limited board space.

Crystals Replacement Considerations

Direct substitutes must match the 26 MHz frequency, 18 pF load capacitance, and 4-SMD package. Verify that alternative manufacturers offer identical ±15 ppm stability and 30 Ohm ESR specifications to maintain circuit performance without redesign.
