18QHTF21-40.00833-PD

Oscillators Overview

The 18QHTF21-40.00833-PD is a 40.00833 MHz crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It features LVCMOS output logic and operates at a supply voltage of 1.8V. The device offers ±50ppm frequency stability and includes a standby (power down) function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Integrated standby mode to reduce power consumption during idle periods
• Compact 4-SMD no-lead surface mount package design

Oscillators Applications

• Portable electronic devices requiring low power operation
• Communication systems utilizing standard clock signals
• Embedded control circuits needing precise timing references

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD package footprint matches the PCB layout requirements. Check for RoHS compliance status if required by project specifications.

Oscillators Selection Notes

Select this component when a low-profile, low-voltage oscillator with standby capability is required. The 1.8V operation suits battery-powered applications. The ±50ppm stability is suitable for general-purpose timing needs. Consider the small 2.0x1.6mm footprint for space-constrained designs.
