AWSCR-4.00CP-T4

Overview

The Abracon LLC AWSCR-4.00CP-T4 is a surface-mount ceramic resonator operating at a nominal frequency of 4 MHz. It features an integrated load capacitance of 30 pF, which simplifies circuit design by eliminating the need for external matching components. The device offers a frequency tolerance of ±0.5% and a stability of ±0.3%. It operates within a temperature range of -25°C to +85°C and has a typical impedance of 30 Ohms. The component is housed in a standard 6030 package measuring 6.0 mm x 3.0 mm x 1.8 mm.

Feature Summary

• Integrated load capacitance eliminates requirement for external capacitors
• Standard SMD footprint facilitates automated assembly processes
• RoHS compliant construction supports environmental regulatory standards

Applications

• Consumer electronics clock generation
• Remote control unit timing circuits
• General purpose microcontroller oscillators

Procurement Notes

Verify that the specific suffix T4 corresponds to the required reel packaging configuration for your production line. Confirm that the -25°C to +85°C operating range aligns with the thermal environment of the target application. Ensure PCB layout guidelines for the 6030 package are followed to maintain electrical performance and mechanical reliability during soldering.

Selection Notes

Select this component when cost reduction is prioritized over high precision. The built-in capacitor reduces bill of materials count compared to quartz crystals requiring discrete loading caps. Consider the ±0.5% tolerance sufficient for non-critical timing applications. Evaluate the 30 Ohm impedance against oscillator drive level specifications to ensure stable operation without overdriving the resonator.

Part Context

This part belongs to the Abracon AWSCR series of ceramic resonators. These devices serve as low-cost alternatives to quartz crystal oscillators in applications where moderate frequency accuracy is acceptable. The series utilizes piezoelectric ceramic materials to provide stable frequency references for digital logic circuits.

Replacement Considerations
