18QHTF21-26.650-PD

Oscillators Overview

The 18QHTF21-26.650-PD is a 26.65 MHz crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates with an LVCMOS output logic and requires a 1.8V supply voltage. The component supports a Standby (Power Down) mode for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Features LVCMOS output interface
• Includes standby power down capability

Oscillators Applications

• Battery-powered portable devices
• Low-power consumer electronics
• Compact embedded systems requiring precise timing

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 26.650 MHz specification. Confirm the package type is 4-SMD No Lead. Ensure the operating temperature range meets the application requirements. Check for RoHS compliance if necessary. Validate the manufacturer source to ensure authenticity.

Oscillators Selection Notes

Select this component when a small form factor is critical due to its 2.0x1.6mm footprint. Choose it for applications requiring low current consumption and a 1.8V supply. Consider it for designs needing a standard XO with LVCMOS outputs. Verify that the frequency stability meets system timing needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies with consistent electrical characteristics. The -PD suffix typically indicates a specific tape-and-reel packaging configuration for automated assembly processes.

Oscillators Replacement Considerations

Direct substitutes must match the 26.65 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pin compatibility and electrical specifications before substitution.
