SXTHM218EC174-32.000M

Crystals Overview

The SXTHM218EC174-32.000M is a 32 MHz fundamental mode crystal oscillator manufactured by Suntsu Electronics, Inc. It operates within an extended temperature range of -30°C to +85°C and maintains a frequency stability of ±25 ppm across this range. The component features a load capacitance of 18 pF and a maximum equivalent series resistance (ESR) of 30 Ohms. It utilizes the HC-49/US surface-mount package configuration with two pads, measuring approximately 11.7mm x 4.4mm. This device is designed for precision timing applications requiring reliable performance in industrial environments.

Crystals Feature Summary

• Surface-mount HC-49/US package design for automated assembly
• Extended industrial temperature operation from -30°C to +85°C
• High frequency stability of ±25 ppm over full operating range

Crystals Applications

• Industrial control systems requiring precise clock signals
• Microcontroller base clock sources in harsh environments
• Communication equipment timing circuits

Crystals Procurement Notes

Verify the specific suffix 'EC174' against official Suntsu documentation to confirm the exact temperature grade and tolerance specifications. Ensure the ordering part number matches the required load capacitance and package type. Cross-reference with authorized distributors to confirm current availability status and lead times before finalizing procurement plans.

Crystals Selection Notes

Select this component when an HC-49/US form factor is required but surface-mount mounting is preferred over through-hole. It is suitable for designs needing ±25 ppm stability at 32 MHz within an extended temperature window. Consider the 18 pF load capacitance requirement for circuit matching. Evaluate ESR limits against driver circuit capabilities.

Crystals Part Context

This part belongs to the SXTHM218 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and temperature grades within the standard HC-49/US footprint. The EC174 suffix typically denotes specific environmental and electrical characteristics distinct from other series variants like DC or CC.

Crystals Replacement Considerations

Direct substitutes must match the 32 MHz frequency, HC-49/US SMD package, 18 pF load capacitance, and ±25 ppm stability. Verify pin compatibility and mechanical dimensions. Consult manufacturer cross-reference lists for approved alternatives.
