LFXTAL085860

Overview

The IQD Frequency Products LFXTAL085860 is a fundamental mode, AT-cut quartz crystal resonator housed in a HC-49/U package. It operates at a nominal frequency of 32.768 kHz with a load capacitance of 12.5 pF. The device features a series resistance of 50 kΩ maximum and a shunt capacitance of 5 pF typical. It supports an operating temperature range from -40°C to +85°C and offers a stability tolerance of ±20 ppm over the full temperature range.

Feature Summary

• Fundamental mode AT-cut quartz construction for stable oscillation
• Standard HC-49/U leaded package format
• Designed for low power consumption applications

Applications

• Real-time clock circuits
• Microcontroller oscillator inputs
• Portable electronic devices requiring precise timekeeping

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct load capacitance and tolerance specifications. Confirm that the HC-49/U package dimensions align with your PCB footprint requirements. Check for any recent updates to the RoHS compliance status or material declarations before finalizing procurement documentation.

Selection Notes

Select this component when a standard 32.768 kHz reference is required for timekeeping functions. Ensure the circuit design accommodates the specified 50 kΩ series resistance limit. Verify that the system load capacitance matches the 12.5 pF requirement to maintain frequency accuracy within the stated ±20 ppm tolerance across the industrial temperature range.

Part Context

This crystal belongs to IQD's general-purpose fundamental mode resonator lineup. It serves as a common timing element for embedded systems where cost-effective, reliable frequency generation is prioritized over ultra-high precision. The HC-49/U form factor remains widely supported in legacy and modern consumer electronics designs.

Replacement Considerations

Cross-reference part numbers such as the Epson SG-3030CA or NDK CXA-32K for equivalent electrical performance. Verify pin compatibility and mounting style differences between competing manufacturers' HC-49/U variants before substitution.
