ABLS7M2-20.000MHZ-D2Y-T

Crystals Overview

The Abracon ABLS7M2-20.000MHZ-D2Y-T is a surface-mount microprocessor crystal operating at a nominal frequency of 20 MHz. It features an equivalent series resistance (ESR) of 60 Ohms and a load capacitance of 18 pF. The component exhibits a frequency tolerance of ±20 ppm at 25°C and a frequency stability of ±30 ppm across the operating temperature range. Designed for robust performance, it supports a maximum drive level of 50 µW and ensures an annual aging rate of ±5 ppm. The unit operates within a temperature range of -40°C to +85°C and utilizes a compact 2-SMD flat lead package measuring 7.0 mm in length, 4.1 mm in width, and 2.0 mm in height.

Crystals Feature Summary

• Reduced footprint compared to standard HC/49US packages, offering a 50% size reduction for space-constrained designs.
• Low profile construction with a maximum height of 2.0 mm, suitable for thin-profile applications.
• Resistance-welded metal package provides high reliability and moisture resistance without requiring pre-reflow baking.
• Compliant with RoHS standards and suitable for lead-free reflow soldering processes.

Crystals Applications

• Microprocessor clock circuits
• Industrial gateway main clocks
• Consumer electronics timing references

Crystals Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure compatibility with the target application requirements. Confirm that the selected variant matches the required frequency tolerance, stability, and temperature range specifications. Cross-reference the manufacturer part number with distributor catalogs to validate current availability and lead times. Ensure that the ordering quantity aligns with the standard factory packaging quantities to optimize procurement efficiency.

Crystals Selection Notes

Select this component when a compact SMD solution is required to replace through-hole HC/49US crystals without altering PCB layout significantly. The 20 MHz frequency is suitable for general-purpose microprocessor clocks and communication interfaces. Consider the 60 Ohm ESR value for oscillator circuit matching to ensure reliable startup. The -40°C to +85°C temperature range makes it appropriate for standard industrial and commercial environments where moderate thermal stability is sufficient.

Crystals Part Context

This part belongs to the ABLS7M2 series, which represents a low-profile, surface-mount version of the traditional HC/49US crystal package. The series is designed to provide a smaller footprint while maintaining the electrical characteristics and reliability associated with Abracon's microprocessor crystal line. It serves as a direct drop-in replacement for larger packages in modern, miniaturized electronic designs.
