SX1B40.000F0810F30

Crystals Overview

The SX1B40.000F0810F30 is a surface-mount passive crystal manufactured by Shenzhen SCTF Electronics. It operates at a nominal frequency of 40 MHz with a frequency tolerance of ±10ppm and a load capacitance of 8pF. The component features an equivalent series resistance (ESR) of 60 Ohms and is housed in a 4-SMD package. This AT-cut crystal is designed for stable timing applications requiring precise frequency control.

Crystals Feature Summary

• AT-cut crystal construction for high stability
• Surface-mount 4-SMD packaging format
• Designed for standard load capacitance requirements

Crystals Applications

• Industrial equipment timing circuits
• Portable electronic devices
• Short-range wireless modules
• Computer systems and modems

Crystals Procurement Notes

Verify the specific manufacturer datasheet to confirm electrical parameters such as ESR and load capacitance match system requirements. Ensure the 4-SMD package dimensions align with PCB footprint constraints. Confirm that the ±10ppm tolerance meets the application's frequency accuracy needs before finalizing procurement.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required with moderate stability. The 8pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level compatibility. Verify temperature range specifications if operating in extreme environments beyond standard commercial ranges.

Crystals Part Context

This part belongs to the SCTF SX1B series of passive crystals. It shares the same package style and basic electrical characteristics with other frequencies in the lineup, such as the SX1B38.400F0810F30 and SX1B50.000F0810F30, differing primarily in resonant frequency.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz passive crystals with identical 8pF load capacitance and similar ESR values. Cross-reference with other manufacturers offering 4-SMD AT-cut crystals to ensure pinout and mechanical compatibility.
