LFXTAL068911

Overview

LFXTAL068911 is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 25 MHz with a load capacitance of 18 pF. The device features a frequency tolerance of ±30 ppm and an equivalent series resistance (ESR) of 50 Ohms. Designed for surface mount applications, it utilizes a 4-SMD, No Lead package configuration. The component supports a standard operating temperature range from -40°C to +85°C.

Feature Summary

• Parallel fundamental resonance mode operation
• Hermetically sealed construction with glass-to-metal seals
• Surface mount compatible 4-SMD no-lead package

Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Communication equipment timing references
• Industrial control system clocks

Procurement Notes

Verify the specific packaging suffix required for your assembly process, as availability may vary between tape-and-reel or cut-tape formats. Confirm that the 18 pF load capacitance matches your circuit design requirements. Ensure the 50 Ohm ESR is compatible with your oscillator driver circuit to guarantee stable startup and operation within the specified temperature range.

Selection Notes

Select this component when a 25 MHz surface-mount crystal with moderate stability is required. The 4-SMD no-lead package offers space efficiency compared to traditional through-hole options. Consider the ±30 ppm tolerance against your system's jitter budget. This part is suitable for general electronics where automotive-grade certification is not mandatory.

Part Context

This component belongs to IQD Frequency Products' standard quartz crystal lineup. It serves as a passive frequency-determining element in electronic circuits. The manufacturer provides comprehensive datasheets detailing electrical characteristics and mechanical dimensions. The product line includes various frequencies and packages to support diverse design needs.

Replacement Considerations

Direct substitutes must match the 25 MHz frequency, 18 pF load capacitance, and 4-SMD no-lead package. Verify equivalent ESR values to ensure circuit compatibility. Check if alternative manufacturers offer identical pinout and dimensional specifications for seamless integration.
