ABM8-29.4912MHZ-B2-T

Crystals Overview

The ABM8-29.4912MHZ-B2-T is a ceramic crystal oscillator manufactured by Abracon LLC, designed for surface-mount applications. It operates at a nominal frequency of 29.4912 MHz with a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. The component features a frequency tolerance of ±20 ppm and a stability of ±50 ppm across the operating temperature range of -20°C to +70°C. Housed in a compact 3.2 mm x 2.5 mm x 0.8 mm package, it utilizes a fundamental mode resonance with a drive level of 10 uW, ensuring reliable performance in space-constrained electronic designs.

Crystals Feature Summary

• Compact surface-mount design suitable for high-density PCB layouts
• Stable frequency output within specified industrial temperature ranges
• Low profile package geometry for minimal board height requirements

Crystals Applications

• Microprocessor clock generation circuits
• Communication interface timing references
• Embedded system control logic synchronization

Crystals Procurement Notes

Verify that the specific part number matches the required frequency and tolerance specifications for your circuit design. Confirm compatibility with the target load capacitance and drive level parameters before integration. Ensure that the operating temperature range aligns with the environmental conditions of the final application to maintain frequency stability and device reliability during operation.

Crystals Selection Notes

Select this component when a small form factor is required alongside precise timing accuracy for digital logic interfaces. Consider the ±50 ppm stability rating against the system's jitter sensitivity requirements. Evaluate the 10 uW drive level to ensure it does not exceed the maximum ratings of the connected oscillator circuitry while maintaining sufficient signal amplitude for reliable switching.

Crystals Part Context

This component belongs to the ABM8 series of ceramic resonators from Abracon, which are engineered for cost-effective timing solutions in consumer and industrial electronics. The series offers various frequency options and package sizes to accommodate different design constraints. As a fundamental mode device, it provides stable oscillation characteristics suitable for general-purpose digital timing applications where high precision quartz crystals may be unnecessary or too costly.

Crystals Replacement Considerations

Direct substitutes include other ABM8 series variants with identical footprint dimensions but differing frequencies or tolerances, such as ABM8-16.000MHZ-B2-T if frequency adjustment is permissible. Cross-reference with similar 3.2x2.5mm ceramic resonators from other manufacturers only if electrical parameters match exactly. Verify pinout compatibility and mounting orientation when replacing with non-Abracon equivalents.
