7R-24.000MDDB-T

Crystals Overview

The TXC Corporation 7R-24.000MDDB-T is a quartz crystal resonator operating at a fundamental frequency of 24 MHz. It features a 6 pF load capacitance and ±20 ppm frequency tolerance at 25°C, with stability maintained within ±20 ppm across the -20°C to +70°C temperature range. The component utilizes a glass-seal construction in a 4-SMD, no-lead package measuring 2.0 mm x 1.6 mm with a maximum height of 0.35 mm. It exhibits an equivalent series resistance (ESR) of 150 Ohms and supports fundamental mode operation.

Crystals Feature Summary

• Glass-seal construction for enhanced environmental durability
• Compact surface-mount footprint suitable for space-constrained designs
• Stable frequency performance across industrial temperature ranges

Crystals Applications

• Microcontroller clock circuits
• Communication module timing references
• Industrial control system oscillators

Crystals Procurement Notes

Verify the specific datasheet revision and manufacturer lot codes upon ordering. Confirm that the glass-seal variant meets your environmental requirements compared to ceramic alternatives. Ensure PCB land pattern dimensions align strictly with the 2.0 mm by 1.6 mm package specifications to prevent soldering defects during assembly.

Crystals Selection Notes

Select this component when a compact 24 MHz reference is required with moderate stability. The 6 pF load capacitance must match the oscillator circuit design. Consider the 150 Ohm ESR value for drive level sensitivity. This glass-seal type offers distinct advantages over standard ceramic crystals in harsh environments requiring robust sealing.

Crystals Part Context

This part belongs to the TXC 7R series of miniature quartz crystals. The series specializes in small-form-factor components utilizing glass-seal technology. These devices are engineered for applications demanding reliable timing signals in limited board space while maintaining consistent electrical characteristics under varying thermal conditions.

Crystals Replacement Considerations

Direct substitutes include the 7V-24.000MAAV-T, though it uses ceramic sealing and different physical dimensions. Verify compatibility regarding load capacitance and ESR values before swapping. Alternative packages may require PCB re-layout due to size differences.
