ABM8N-20.0000MHZ-18-D1G-T3

Crystals Overview

The ABM8N-20.0000MHZ-18-D1G-T3 is a parallel fundamental quartz crystal oscillator manufactured by Abracon LLC. It operates at a nominal frequency of 20 MHz with a frequency tolerance of ±10 ppm and a frequency stability of ±15 ppm over the operating temperature range. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 3.2 mm x 2.5 mm x 1.0 mm. The device supports a maximum drive level of 10 µW and functions within a temperature range of -40°C to +85°C.

Crystals Feature Summary

• Hermetically sealed glass package for high reliability
• Ultra-miniature surface mount design suitable for thin equipment
• RoHS compliant and lead-free construction

Crystals Applications

• General purpose timing circuits
• Microcontroller clock sources
• Communication modules requiring stable 20 MHz reference

Crystals Procurement Notes

Verify the specific suffix D1G against the official Abracon datasheet to confirm the exact frequency tolerance and stability ratings, as these parameters can vary significantly across different suffixes within the ABM8N series. Ensure the ordering code matches the required load capacitance and package variant precisely to avoid integration errors in the final assembly.

Crystals Selection Notes

Select this component when a hermetically sealed crystal is required for harsh environments or high reliability applications. The 18 pF load capacitance must match the oscillator circuit design. Compare ESR and stability requirements against alternative packages like ABM8 or ABM8W if space constraints or cost factors differ from the sealed glass option.

Crystals Part Context

This part belongs to the ABM8N series of ultra-miniature ceramic and glass-sealed crystals. It shares the 3225 footprint with other Abracon variants but distinguishes itself through the hermetic sealing process, which provides superior protection against moisture and contaminants compared to standard epoxy-sealed counterparts.

Crystals Replacement Considerations

ABM8-20.000MHZ-N3G offers similar electrical characteristics but uses a ceramic seal rather than glass. ABM8W-20.0000MHZ-6-B7Y-T3 is a wider variant with different load capacitance. Verify pin compatibility and thermal performance before substituting.
