LFXTAL003215B

Overview

The LFXTAL003215B is a parallel fundamental quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 12 MHz with a load capacitance of 30 pF and a frequency tolerance of ±30 ppm. The component features a maximum equivalent series resistance (ESR) of 40 Ohms and supports a drive level of 1 mW. Designed for through-hole mounting, it utilizes the HC-49/US package style with radial termination. The unit functions within an operating temperature range of -10°C to +60°C.

Feature Summary

• Hermetically sealed construction using resistance welding in an inert atmosphere
• Glass-to-metal seals on leads for environmental protection
• Standard industry leaded package design

Applications

• General-purpose clock signal generation
• Microcontroller timing circuits
• Communication interface synchronization

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical parameters and packaging configuration. Ensure that ordering requirements align with current production status and availability constraints provided by authorized distributors. Cross-reference datasheet specifications for thermal and mechanical limits before integration.

Selection Notes

Select this component when a standard 12 MHz reference is required for through-hole applications. The HC-49/US form factor provides compatibility with common PCB footprints. Confirm that the circuit drive level does not exceed 1 mW to prevent frequency drift or damage. Verify that the 30 pF load capacitance matches the oscillator circuit design requirements.

Part Context

This part belongs to the LFXTAL series of quartz crystals produced by IQD Frequency Products. The series includes various frequencies and package styles, such as HC-49 and SMD variants. The LFXTAL003215B specifically represents a fundamental mode crystal optimized for general electronic timing applications requiring stable frequency output.

Replacement Considerations

Direct substitutes include other 12 MHz HC-49/US crystals from manufacturers like Epson or NDK. Ensure replacement parts match the 30 pF load capacitance and 40 Ohm ESR specifications. Verify that alternative components support the same operating temperature range and drive level requirements.
