LFXTAL003186BULK

Overview

The LFXTAL003186BULK is a quartz crystal resonator manufactured by IQD Frequency Products. It operates at a fundamental frequency of 20.0000 MHz with a load capacitance of 20 pF. The component features a frequency tolerance and stability of ±20 ppm. It utilizes an HC-49/4H package style, designed for through-hole mounting with radial termination. The device supports a maximum series resistance (ESR) of 50 ohms and functions within a temperature range of -10°C to +70°C. The unit is supplied in bulk packaging.

Feature Summary

• Provides stable 20 MHz timing reference via fundamental mode quartz resonance
• Designed for through-hole integration using standard HC-49/4H housing
• Maintains ±20 ppm frequency accuracy across specified operating temperatures

Applications

• Microcontroller clock circuits
• Communication interface timing
• General-purpose digital logic synchronization

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet to ensure compatibility with design requirements. Confirm that the HC-49/4H form factor aligns with PCB layout constraints. Check RoHS compliance status and lead times directly with authorized distributors or IQD sales offices prior to finalizing procurement orders.

Selection Notes

Select this component when a 20 MHz through-hole solution is required with moderate stability needs. Ensure the circuit design accommodates the 20 pF load capacitance requirement. Verify that the operating environment remains within the -10°C to +70°C range. Compare ESR specifications against oscillator drive levels to prevent over-driving the crystal.

Part Context

This part belongs to the IQD LFXTAL series of general-purpose quartz crystals. It represents a standard commercial-grade timing element suitable for non-critical applications. The HC-49/4H package is widely used in legacy and modern electronics for its robust mechanical structure and ease of manual or automated insertion.

Replacement Considerations

Cross-reference equivalent parts from other manufacturers offering 20 MHz, 20 pF, HC-49/4H crystals with ±20 ppm tolerance. Ensure electrical parameters such as ESR and drive level sensitivity match the original design specifications before substitution.
