AWSZT-4.00MGD-T

Overview

The AWSZT-4.00MGD-T is a surface-mount ceramic resonator manufactured by Abracon LLC, designed for precise frequency control in electronic circuits. It operates at a nominal frequency of 4 MHz with a frequency stability of ±0.3%. The component features an impedance of 30 Ohms and functions within a temperature range of -25°C to +85°C. Its physical dimensions are 7.40 mm in length, 3.40 mm in width, and 1.8 mm in height, providing a compact footprint suitable for space-constrained designs.

Feature Summary

• Miniaturized surface-mount package for automated assembly
• High accuracy frequency stability for reliable timing
• Robust construction for consistent performance

Applications

• Microcontroller clock sources
• Timing circuits in consumer electronics
• Communication device synchronization

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when reviewing distributor listings. Confirm that the ±0.3% stability rating matches the design requirements, as other variants like the T4 suffix offer different tolerances. Ensure the operating temperature range of -25°C to 85°C aligns with the environmental conditions of the target application before finalizing procurement.

Selection Notes

Select this component when a cost-effective alternative to quartz crystals is required for moderate precision applications. The 30 Ohm impedance should be compatible with the driving circuit's load requirements. Consider the 4 MHz frequency against available microcontroller internal oscillators or external clock inputs to ensure proper integration without additional frequency division or multiplication stages.

Part Context

This part belongs to Abracon's AWSZT series of miniaturized ceramic resonators. The series offers various frequency options and tolerance levels, such as the AWSZT-MGD base model. The AWSZT-4.00MGD-T specifically targets the 4 MHz market segment, distinguishing itself from higher-frequency variants through its specific resonance characteristics and stability profile tailored for standard digital logic timing.

Replacement Considerations

Direct substitutes include the AWSZT-4.00MGD-T4, which shares identical physical dimensions but differs in frequency stability (±0.5%). Verify if the looser tolerance of the T4 variant meets system requirements. Cross-reference with other manufacturers' 4 MHz SMD ceramic resonators ensuring matching impedance and package size for pin-compatible replacement.
