LFXTAL081609

Overview

The LFXTAL081609 is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a fundamental frequency of 25 MHz with a load capacitance of 8 pF. The component exhibits a frequency tolerance of ±10 ppm and stability of ±20 ppm. Key electrical parameters include an equivalent series resistance (ESR) of 150 Ohms and a drive level of 1 mW. The package is a 4-SMD, no-lead type measuring 1.60 mm x 1.20 mm x 0.45 mm maximum height. It supports a temperature range from -40°C to +85°C.

Feature Summary

• Fundamental mode operation for precise timing applications
• Compact 4-SMD no-lead surface mount package design
• Wide industrial operating temperature range capability

Applications

• Microcontroller clock sources
• Communication interface timing circuits
• Industrial control system oscillators

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and specifications. Confirm that the requested variant matches the required load capacitance and frequency tolerance for the target circuit design. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when a 25 MHz fundamental frequency with tight ±10 ppm tolerance is required in a small footprint. Ensure the application circuit provides the specified 8 pF load capacitance to maintain accuracy. Verify that the 150 Ohm ESR value is compatible with the oscillator circuit's driving requirements and that the -40°C to +85°C temperature range meets environmental constraints.

Part Context

This component belongs to the IQXC-26 series of quartz crystals from IQD Frequency Products. It serves as a passive frequency control element within larger electronic assemblies. The device functions as a resonator rather than an active oscillator, requiring external amplifier circuitry to generate a clock signal. It is distinct from voltage-controlled or temperature-compensated oscillator variants.

Replacement Considerations

LFXTAL081609 is functionally equivalent to the CTS-Frequency Controls part number 416WF25012IKR based on matching electrical parameters and physical dimensions.
