AWCR-3.58MD

Overview

The AWCR-3.58MD is a ceramic resonator manufactured by Abracon LLC, designed for through-hole mounting applications. It operates at a standard frequency of 3.58 MHz with a frequency tolerance of ±0.5% and a stability of ±0.3%. The component features built-in capacitors with a value of 30 pF and an equivalent series resistance (ESR) of 30 Ohms. It supports supply voltages of 5 VDC and 12 VDC, functioning within an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates built-in capacitors to simplify circuit design
• Supports dual voltage operation at 5 VDC and 12 VDC
• Provides high frequency stability of ±0.3%
• Utilizes through-hole packaging for robust mechanical attachment

Applications

• Consumer electronics requiring precise timing references
• Industrial control systems operating in varied temperatures
• Embedded microcontroller clock sources

Procurement Notes

Verify the specific package type and lead time requirements against project schedules before ordering. Confirm that the through-hole footprint matches the target PCB layout. Ensure the 30 pF internal capacitance aligns with the oscillator circuit design specifications. Check for any RoHS compliance documentation if required by regional regulations.

Selection Notes

Select this component when a cost-effective timing solution with integrated capacitors is needed. The through-hole format suits applications prioritizing mechanical durability over space constraints. Consider the ±0.5% tolerance sufficient for general-purpose clocks but verify against stricter jitter requirements. Evaluate the 30 Ohm ESR compatibility with the driving gate circuitry.

Part Context

This part belongs to the AWCR series of ceramic resonators from Abracon LLC. These components are engineered as alternatives to quartz crystals where size and cost efficiency are critical. The series offers various frequencies ranging from 2.0 MHz to 20.00 MHz, providing designers with flexible options for different clock speeds while maintaining consistent performance characteristics across the product line.

Replacement Considerations

Direct substitutes include other 3.58 MHz ceramic resonators with similar 30 pF capacitance and through-hole packages. Verify pin compatibility and electrical parameters such as ESR and tolerance before swapping. Cross-reference with Abracon's own variants like HWZT-3.58MD if available, ensuring functional equivalence.
