SXMH26.000F2020F30

Crystals Overview

The SXMH26.000F2020F30 is a passive crystal resonator manufactured by Shenzhen SCTF Electronics, designed for precision timing applications. It operates at a fundamental frequency of 26 MHz with a load capacitance of 20 pF and a frequency tolerance of ±20 ppm. The component utilizes the HC-49/US package style, providing a robust surface-mount form factor suitable for automated assembly processes. It features an equivalent series resistance (ESR) of 25 Ohms, ensuring stable oscillation characteristics within electronic circuits. The device is engineered to function reliably across an extended industrial temperature range of -40°C to +85°C, making it appropriate for demanding environmental conditions where consistent clock signal generation is critical.

Crystals Procurement Notes

Verify that the requested part number matches the specific electrical parameters required for your design, particularly the 26 MHz frequency and 20 pF load capacitance. Confirm compatibility with your PCB footprint, as the HC-49/US package has distinct dimensional requirements compared to other crystal packages. Ensure that the supplier provides authentic components from Shenzhen SCTF Electronics to guarantee performance reliability and adherence to the specified ±20 ppm tolerance standards.

Crystals Selection Notes

Select this component when a 26 MHz reference frequency is required for digital logic or communication interfaces. The HC-49/US package offers a balance between size and mechanical stability for surface-mount applications. Consider the ±20 ppm tolerance if high-precision timing is not critical, and verify that the operating environment falls within the -40°C to +85°C range to ensure long-term frequency stability without additional compensation.

Crystals Part Context

This crystal resonator belongs to the standard passive crystal family used in oscillator circuits. It requires external amplifier circuitry to generate a square wave output, distinguishing it from active crystal oscillators. The HC-49/US designation refers to a specific metal can-style surface-mount package that provides shielding against electromagnetic interference while maintaining a low profile suitable for modern printed circuit board layouts.

Crystals Replacement Considerations

Substitute parts must match the 26 MHz frequency, 20 pF load capacitance, and HC-49/US package dimensions. Verify that alternative manufacturers offer comparable ±20 ppm tolerance and ESR specifications to ensure circuit compatibility.
