LFXTAL059646

Overview

The LFXTAL059646 is a surface-mount quartz crystal resonator from the CFPX-180 series, manufactured by IQD Frequency Products. It operates at a fundamental frequency of 30 MHz with a frequency tolerance of ±20 ppm and a frequency stability of ±30 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 40 Ohms. Designed for base mode operation, it supports a temperature range of -40°C to +85°C. The physical dimensions are 3.20 mm in length, 2.50 mm in width, and a maximum height of 0.80 mm, housed in a 4-SMD, no-lead package.

Feature Summary

• Surface-mount design in a compact 4-SMD no-lead package suitable for automated assembly.
• Fundamental mode operation providing stable oscillation at 30 MHz.
• Wide industrial temperature rating supporting environments from -40°C to +85°C.

Applications

• General-purpose clock generation for microcontrollers and digital logic circuits.
• Timing references in consumer electronics and computing devices.
• Industrial control systems requiring reliable frequency standards.

Procurement Notes

Verify the specific packaging suffix required for your production line, as this part is available in both Cut Tape (CT) and Tape & Reel (TR) configurations. Confirm that the 18 pF load capacitance matches your circuit design requirements. Ensure the 40 Ohm ESR is compatible with your oscillator circuit's drive level specifications to prevent over-driving the crystal.

Selection Notes

Select this component when a 30 MHz fundamental frequency is required in a small surface-mount footprint. The CFPX-180 series offers a balance of size and performance for general applications. Consider the ±20 ppm tolerance if tighter stability is not critical. Verify that the operating temperature range meets the environmental conditions of the target application.

Part Context

This crystal belongs to the CFPX-180 series, which provides various frequencies in a standardized 3.20 x 2.50 mm SMD package. IQD Frequency Products manufactures these components using established quartz processing techniques. The series is designed to meet standard industry requirements for timing accuracy and reliability in mass-produced electronic equipment.

Replacement Considerations

Direct substitutes must match the 30 MHz frequency, 18 pF load capacitance, and 4-SMD no-lead package dimensions. Check equivalent parts from other manufacturers for identical electrical parameters, including ESR and frequency tolerance. Ensure any replacement part maintains the same temperature range and mounting style for board compatibility.
