LFXTAL024985B

Overview

The LFXTAL024985B is a parallel fundamental quartz crystal from the HC49/4H series manufactured by IQD Frequency Products. It operates at a nominal frequency of 3.2768 MHz with a load capacitance of 12 pF. The component features a frequency tolerance of ±30 ppm and frequency stability of ±50 ppm. Designed for through-hole mounting, it utilizes radial termination and has an ESR of 40 Ohms. The drive level is specified at 0.5 mW (500 µW).

Feature Summary

• Hermetically sealed in an inert atmosphere with glass-to-metal seals on leads.
• Standard industry leaded package construction.
• Resistance welded design for reliability.

Applications

• Clock generation circuits
• Microcontroller timing references
• General-purpose digital electronics

Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm exact packaging and tolerance grades. Ensure the load capacitance requirement matches the circuit design specifications before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference the part number with official distributor catalogs to validate availability and authenticity.

Selection Notes

Select this component when a standard HC49/4H through-hole crystal is required for 3.2768 MHz applications. The 12 pF load capacitance must align with the oscillator circuit design. Consider the ±30 ppm tolerance for basic timing accuracy requirements. Verify that the operating temperature range meets the environmental conditions of the intended application.

Part Context

This part belongs to the HC49/4H series of quartz crystals, which are widely used in consumer and industrial electronics. IQD Frequency Products provides these components as part of their comprehensive frequency control portfolio. The HC49/4H package is a standard form factor compatible with many existing PCB layouts.

Replacement Considerations

LFXTAL024985BULK is listed as an alias or bulk packaging variant. Verify pin compatibility and electrical parameters before substituting with other manufacturers' HC49/4H crystals.
