AWCR-4.00MD

Overview

The AWCR-4.00MD is a ceramic resonator manufactured by Abracon LLC, designed for through-hole mounting applications. It operates at a nominal frequency of 4 MHz with a frequency tolerance of ±0.5% and a stability of ±0.3%. The component features a built-in load capacitance of 30 pF and a maximum series resistance of 30 Ohms. It supports a supply voltage up to 5 V and functions within a temperature range of -25°C to +85°C. The package dimensions are 10 mm in length, 5 mm in width, and 10 mm in height, utilizing a 3-pin configuration with a 2.5 mm lead spacing.

Feature Summary

• Integrates internal capacitors to simplify circuit design
• Provides stable oscillation for microprocessor clock signals
• Supports standard through-hole assembly processes

Applications

• Microprocessor clock generation
• General-purpose timing circuits
• Consumer electronics control boards

Procurement Notes

Verify the specific suffix and manufacturing date code against current Abracon documentation to ensure compliance with RoHS standards and material composition requirements. Confirm that the 3-pin through-hole footprint matches the target PCB layout, as legacy components may have updated mechanical specifications or packaging formats that differ from historical bulk distribution data.

Selection Notes

Select this component when a cost-effective timing solution is required for low-frequency applications. Ensure the system power supply remains within the 5 V operational limit. Verify that the ±0.5% initial tolerance meets the system's clock accuracy requirements before finalizing the bill of materials.

Part Context

This part belongs to the AWCR series of ceramic resonators from Abracon. These components serve as alternatives to quartz crystals where high precision is not critical. The series offers a balance between performance and cost for basic timing needs in embedded systems.
