SXT21420EB38-37.400M

Crystals Overview

The SXT21420EB38-37.400M is a surface-mount crystal oscillator manufactured by Suntsu Electronics, Inc. It operates at a fundamental frequency of 37.4 MHz with a frequency stability tolerance of ±15 ppm. The component features a load capacitance of 20 pF and an equivalent series resistance (ESR) of 100 Ohms. It utilizes a 4-SMD, no-lead package configuration designed for automated assembly processes. This piezoelectric resonator is engineered to provide precise timing signals for digital circuits requiring stable clock references within specified operational temperature ranges.

Crystals Feature Summary

• Provides high-frequency stability with ±15 ppm tolerance for accurate timing applications
• Utilizes a compact 4-SMD no-lead package suitable for space-constrained PCB designs
• Operates with a standard 20 pF load capacitance for easy integration into existing circuit topologies

Crystals Applications

• Microcontroller clock generation in embedded systems
• Communication module timing references
• Digital signal processing circuit synchronization

Crystals Procurement Notes

Verify the specific suffix EB38 against official Suntsu Electronics documentation to confirm package dimensions and terminal plating specifications. Ensure that the required ±15 ppm stability meets the system's jitter and phase noise requirements. Cross-reference the 100 Ohm ESR value with the oscillator circuit design to guarantee proper startup conditions and sustained oscillation amplitude.

Crystals Selection Notes

Select this component when a 37.4 MHz reference is required with tight frequency tolerance. The 4-SMD form factor supports reflow soldering processes. Confirm that the 20 pF load capacitance matches the host oscillator's internal capacitive requirements. Evaluate the thermal performance characteristics if the application involves significant ambient temperature variations beyond standard commercial ranges.

Crystals Part Context

This part belongs to the SXT214 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and stability grades. The specific model integrates a quartz resonator element within a standardized footprint. It serves as a passive timing component distinct from active oscillator modules, requiring external amplifier circuitry to function.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, ±15 ppm stability, 20 pF load capacitance, and 4-SMD no-lead package geometry. Verify pin compatibility and mounting pad layout equivalence to ensure mechanical fit without PCB redesign.
