SXTHM219BA484-24.576M

Crystals Overview

The SXTHM219BA484-24.576M is a MHz crystal oscillator manufactured by Suntsu Electronics, Inc., designed for precise frequency control applications. It operates at a nominal frequency of 24.576 MHz with a frequency stability tolerance of ±30 ppm. The component features a load capacitance of 19 pF and an equivalent series resistance (ESR) of 30 Ohms. It utilizes the HC-49/US package style, which is a standard through-hole or surface-mount configuration depending on specific variant implementation, though datasheets often associate this series with SMD options. The device is rated for an operating temperature range of -20°C to +70°C, ensuring reliability in commercial environments.

Crystals Feature Summary

• Provides stable frequency generation at 24.576 MHz with high precision.
• Designed for robust performance within commercial temperature ranges.
• Features low equivalent series resistance for efficient circuit integration.

Crystals Applications

• Medical devices requiring ultra-reliable timekeeping
• Microcontroller clock sources

Crystals Procurement Notes

Verify the exact package type (through-hole vs. surface mount) against the manufacturer's latest datasheet, as part numbers may vary slightly between HC-49/U and SMD variants. Confirm RoHS compliance status directly with the supplier. Ensure the load capacitance matches your circuit design requirements before ordering. Check current availability as stock levels fluctuate.

Crystals Selection Notes

Select this component when a 24.576 MHz reference is required for UART or baud rate generation due to its commonality in serial communication standards. Consider the ±30 ppm stability if tighter synchronization is needed compared to lower-grade crystals. Evaluate the HC-49/US form factor for board space constraints and mounting preferences relative to smaller SMD alternatives.

Crystals Part Context

This part belongs to the SXTHM series from Suntsu Electronics, which focuses on cost-effective frequency control solutions. The series includes various frequencies and stability grades, such as ±50 ppm variants like the SXTHM219AA274. The BA484 suffix likely denotes specific packaging or tolerance characteristics within the product line.

Crystals Replacement Considerations

Direct substitutes include other 24.576 MHz crystals with similar ESR and load capacitance. Verify pin compatibility and thermal ratings. Cross-reference with generic HC-49/US specifications if sourcing from alternative distributors.
