18QHTF21-33.825-PD

Oscillators Overview

The 18QHTF21-33.825-PD is a 33.825 MHz crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a supply voltage of 1.8V and features an LVCMOS output signal. The device supports a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The unit offers frequency stability of ±50ppm and functions within an operating temperature range of -40°C to 85°C. Maximum supply current is specified at 23mA.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Includes standby power-down functionality to reduce consumption
• Provides high frequency stability of ±50ppm across the industrial temperature range

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Industrial control systems operating in wide temperature environments
• Communication equipment utilizing standard clock signals

Oscillators Procurement Notes

Verify the specific frequency tolerance and package marking against official datasheets before integration. Confirm that the 1.8V supply rail meets the maximum current requirements during active operation. Ensure the PCB layout accommodates the 4-SMD no-lead footprint dimensions accurately to maintain signal integrity and thermal performance.

Oscillators Selection Notes

Select this component when a small form factor and low voltage operation are critical. The ±50ppm stability suits applications where moderate precision is required without the cost of higher-grade oscillators. Consider the standby feature if power management is a priority in battery-operated designs.
