3QHTF21-145.500-PD

Oscillators Overview

The 3QHTF21-145.500-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a nominal frequency of 145.5 MHz. It utilizes an LVCMOS output logic and requires a 3.3V supply voltage. The device features a maximum supply current of 29 mA and maintains a frequency stability of 50 ppm. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The component supports a standby power-down mode for energy efficiency.

Oscillators Feature Summary

• Supports low-voltage CMOS output logic for digital interface compatibility
• Includes standby power-down functionality to reduce consumption
• Utilizes a surface-mount crystal resonator base

Oscillators Applications

• Digital signal processing systems requiring precise clock timing

• Embedded systems needing compact clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 3.3V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific handling instructions regarding electrostatic discharge during assembly.

Oscillators Selection Notes

Select this model when a 145.5 MHz clock source is required with LVCMOS outputs. Consider the 50 ppm stability if tight frequency accuracy is necessary. The small 2.0x1.6 mm package suits space-constrained designs. Evaluate the 29 mA current draw against total system power budgets. Verify compatibility with the intended operating temperature range.

Oscillators Part Context

This part belongs to the 3QHTF21 series of SMD oscillators from Mercury Electronics. The series includes various frequencies such as 10.145 MHz and 145.2 MHz. These components are designed for general-purpose clock generation in electronic circuits. The manufacturer specializes in quartz-based frequency control products.

Oscillators Replacement Considerations

Direct substitutes within the same series include models like 3QHTF21-145.200-PD, though frequency differs. Cross-referencing with other manufacturers' 145.5 MHz LVCMOS oscillators in 4-SMD packages may be possible if electrical parameters match.
