AWSCR-8.00CE-C33-T

Overview

The AWSCR-8.00CE-C33-T is a surface-mount ceramic resonator manufactured by Abracon LLC, operating at a nominal frequency of 8 MHz. It features an integrated load capacitance of 33 pF and exhibits a frequency tolerance of ±0.5% with a stability of ±0.3%. The component has a series resistance of 40 Ohms and operates within a temperature range of -25°C to +85°C. Its physical dimensions are 3.70 mm in length, 1.00 mm in width, and 1.00 mm in height, housed in a standard 3-SMD package.

Feature Summary

• Integrates internal capacitors to simplify circuit design and reduce external component count.
• Provides stable frequency generation suitable for microcontroller clock applications.
• Offers compact surface-mount packaging for automated assembly processes.

Applications

• Microcontroller system clocking
• Communication module timing references
• General-purpose digital circuit oscillators

Procurement Notes

Verify the specific suffix 'C' against the required datasheet revision, as it may denote distinct performance characteristics compared to other variants like 'CELA'. Confirm that the 33 pF integrated capacitance aligns with the target oscillator circuit requirements. Ensure the -25°C to +85°C operating range meets the environmental specifications of the final application.

Selection Notes

Select this component when a cost-effective, compact solution for 8 MHz timing is required without external capacitors. Compare the ±0.3% stability against stricter crystal requirements if higher precision is needed. Evaluate the 40 Ohm impedance against the driving capability of the host oscillator circuit to ensure reliable startup.

Part Context

This part belongs to the Abracon AWSCR series of ceramic resonators, designed as alternatives to quartz crystals where moderate stability suffices. The CE variant typically denotes specific commercial grade performance. It serves as a foundational timing element in consumer electronics and industrial control systems requiring precise but not ultra-high-stability frequencies.

Replacement Considerations

Public confirmed substitute: CSTNE8M00G550000R0 (Murata Electronics). Verify pinout compatibility and electrical parameter equivalence before substitution.
