AWSCR-3.58CPLA-C33-T4

Overview

The AWSCR-3.58CPLA-C33-T4 is a surface-mount ceramic resonator from the Abracon AWSCR-CPLA series, operating at a nominal frequency of 3.58 MHz. It features an integrated load capacitance of 33 pF and a typical impedance of 30 Ohms. The component exhibits a frequency tolerance of ±0.5% and a frequency stability of ±0.3%. Designed for industrial applications, it operates within a temperature range of -40°C to +85°C. The device utilizes a standard 6.00mm x 3.00mm x 1.50mm SMD package with three terminals.

Feature Summary

• Integrates internal matching capacitors to reduce external component count
• Provides stable clock signals for microcontroller circuits
• Supports standard surface-mount reflow soldering processes

Applications

• Microcontroller clock generation in consumer electronics
• Timing circuits for remote control devices
• Clock sources for home appliance control boards

Procurement Notes

Verify the specific suffix 'T4' corresponds to tape and reel packaging requirements. Confirm that the 33 pF internal capacitance aligns with the target oscillator circuit design. Ensure compliance with RoHS directives for the intended market. Validate that the 30 Ohm impedance matches the driving capability of the host MCU pins.

Selection Notes

Select this component when cost reduction is prioritized over high-precision timing. Suitable for applications where ±0.5% tolerance is acceptable. Consider the 3.58 MHz frequency for specific audio or communication sub-carrier needs. Evaluate PCB space constraints against the 6x3 mm footprint.

Part Context

This part belongs to the AWSCR-CPLA family of ceramic resonators. These components serve as low-cost alternatives to quartz crystals by eliminating the need for discrete load capacitors. The series is designed for general-purpose timing applications where extreme frequency accuracy is not critical.

Replacement Considerations

AWSCR-3.58CPLB-C30-T4 offers similar functionality with different internal capacitance (30 pF) and impedance characteristics. Verify circuit compatibility before substitution due to potential oscillation startup differences.
