SXT1148DB38-24.000M

Crystals Overview

The SXT1148DB38-24.000M is a 24 MHz surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It features a 4-SMD, No Lead package with dimensions of 1.6 x 1.2 mm. The component operates within a temperature range of -30°C to +85°C and has a load capacitance of 8 pF. Frequency stability is specified at ±30 ppm, with a normal temperature frequency tolerance of ±25 ppm. Equivalent Series Resistance (ESR) is rated at 150 Ohms for the 24 MHz frequency.

Crystals Feature Summary

• Ultra-compact 1.6 x 1.2 mm 4-pad SMT footprint designed for high-density PCB layouts.
• Dual grounding pads integrated into the package structure to enhance electromagnetic interference resistance compared to standard 2-pad designs.
• AT-cut fundamental frequency design ensuring reliable oscillation startup characteristics across operating conditions.

Crystals Applications

• Bluetooth wireless modules requiring stable clock sources
• Wi-Fi communication interfaces in compact devices
• Industrial wireless sensor networks

Crystals Procurement Notes

Verify the specific frequency tolerance requirement against the datasheet, as conflicting data exists regarding ±20 ppm versus ±30 ppm specifications. Confirm the operating temperature grade matches the application environment, noting the -30°C to +85°C rating. Ensure the 8 pF load capacitance aligns with the host circuit design. Check current availability status as stock levels may vary.

Crystals Selection Notes

Select this component when space constraints necessitate a 1.6 x 1.2 mm footprint. The 4-pad configuration offers superior noise immunity compared to smaller 2-pad alternatives. Consider the ESR value of 150 Ohms for matching network calculations. This part is suitable for applications where moderate frequency stability is acceptable without requiring active temperature compensation.

Crystals Part Context

This model belongs to the SXT114 series of miniature crystals from Suntsu Electronics. The series utilizes a standardized naming convention where '114' denotes the series, '12' indicates the 1.6 x 1.2 mm package, and suffixes define tolerance and temperature ranges. The SXT114 series covers frequencies from 24 MHz to 54 MHz, targeting consumer and industrial wireless applications.

Crystals Replacement Considerations

No public substitute part numbers are confirmed in the provided documentation. Direct replacement requires identical electrical parameters including 24 MHz frequency, 8 pF load capacitance, and compatible ESR values. Verify pinout compatibility despite the leadless package design.
