LFXTAL003115BULK

Overview

The LFXTAL003115BULK is a fundamental mode quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 32.768 kHz and utilizes an HC-49/SD through-hole package with radial termination. The component features a load capacitance of 12.5 pF and offers a frequency tolerance of ±30 ppm. It maintains a frequency stability of ±50 ppm across the operating temperature range of -20°C to +70°C. The series resistance is specified at 50 kΩ, and it supports a maximum drive level of 100 µW.

Feature Summary

• Hermetically sealed in an inert atmosphere using glass-to-metal seals on leads for environmental protection
• Fundamental resonance mode operation optimized for low-frequency timing applications
• Standard two-leg HC-49/SD leaded package configuration compatible with automated insertion processes

Applications

• Real-time clock circuits in consumer electronics
• Microcontroller system oscillators
• Low-power embedded device timing sources

Procurement Notes

Verify the specific packaging suffix against official IQD documentation to confirm bulk supply conditions. Ensure the load capacitance matches the target circuit design requirements. Confirm that the operating temperature range meets the intended application environment. Check RoHS compliance status directly from the manufacturer's declaration. Validate the drive level specifications to prevent over-driving the crystal element.

Selection Notes

Select this component when a standard 32.768 kHz reference is required for through-hole designs. Consider the 50 kΩ series resistance for oscillator circuit compatibility. Evaluate the ±30 ppm initial tolerance against system accuracy needs. Assess the HC-49/SD footprint constraints within the PCB layout. Compare performance metrics against alternative fundamental mode crystals if tighter stability is necessary.

Part Context

This part belongs to the IQD LFXTAL series of general-purpose quartz crystals. It represents a standard industry solution for timekeeping functions. The product line emphasizes reliability and cost-effectiveness for commercial applications. IQD Frequency Products supplies these components globally as part of their passive frequency control portfolio.

Replacement Considerations

Cross-reference equivalent parts from other manufacturers offering 32.768 kHz fundamental crystals in HC-49/SD packages. Verify dimensional compatibility and pin spacing before substitution. Ensure electrical parameters such as load capacitance and ESR remain within acceptable limits for the existing oscillator circuit.
