ABLSG-18.000MHZ-D2Y-T

Crystals Overview

The ABLSG-18.000MHZ-D2Y-T is a parallel fundamental quartz crystal manufactured by Abracon LLC, designed for surface mount applications. It operates at a nominal frequency of 18 MHz with a frequency tolerance of ±20 ppm and stability of ±30 ppm. The component utilizes an HC-49/US package configuration featuring three leads, where the third lead serves as a grounded case to minimize electromagnetic interference. Key electrical parameters include a load capacitance of 18 pF and an equivalent series resistance (ESR) of 40 Ohms. It supports a drive level of 100 µW and exhibits aging of 5 ppm per year. The device functions within a temperature range of -40°C to +85°C.

Crystals Procurement Notes

Verify the specific suffix D2Y-T against official Abracon documentation to confirm tape and reel packaging and lead finish specifications. Ensure the ordered part number matches the required 18 MHz frequency and 18 pF load capacitance. Confirm compliance requirements such as RoHS and REACH status directly from the manufacturer's latest datasheet before finalizing procurement orders.

Crystals Selection Notes

Select this component when a surface mount solution with superior electromagnetic interference shielding is required compared to standard two-lead crystals. The grounded case feature makes it suitable for sensitive RF environments. Verify that the circuit design accommodates the 18 pF load capacitance and that the operating temperature range of -40°C to +85°C aligns with the application's thermal profile.

Crystals Part Context

This part belongs to the ABLSG series of surface mount crystals from Abracon. The series is characterized by its HC-49/US form factor adapted for SMD mounting. The ABLSG line provides fundamental frequency options with various load capacitances and tolerances, catering to general-purpose timing applications requiring reliable performance in compact electronic assemblies.

Crystals Replacement Considerations

Direct substitutes must match the 18 MHz frequency, 18 pF load capacitance, HC-49/US SMD 3-lead package, and ±20 ppm tolerance. Verify pinout compatibility, specifically the grounded third lead function, to ensure proper PCB layout integration without redesign.
