Overview
The AWSZT-40.00CW-T is a ceramic resonator manufactured by Abracon LLC, designed for surface-mount applications. It operates at a nominal frequency of 40 MHz and belongs to the AWSZT-CW series. The component features a four-pin SMD package with dimensions of 2.50mm in length and 2.00mm in width. Key electrical specifications include an input impedance of 50 Ohms, a frequency tolerance of ±10.5%, and a stability rating of ±10.2%. This device is supplied in tape and reel packaging for automated assembly processes.
Feature Summary
- Four-pin surface-mount configuration for compact PCB integration
- Integrated ceramic construction providing stable oscillation
- Designed for high-volume manufacturing via tape and reel supply
Applications
- Microcontroller clock generation circuits
- General-purpose digital signal processing timing
- Consumer electronics oscillator modules
Procurement Notes
Verify the specific suffix 'CW' against datasheet requirements to ensure compatibility with circuit impedance and load capacitance needs. Confirm that the ±10.5% tolerance aligns with system timing accuracy constraints before finalizing procurement orders.
Selection Notes
Select this component when a low-cost, standard-tolerance clock source is required for non-critical timing applications. The 50-Ohm impedance and 40MHz frequency are suitable for general digital logic interfaces where precise frequency stability is not a primary design constraint.
Part Context
This part belongs to the AWSZT-CW series of ceramic resonators from Abracon. Unlike the CV series which includes internal capacitors, the CW series typically functions as a bare resonator element requiring external load components or specific driver configurations to achieve proper oscillation within the target application circuit.
Replacement Considerations
Direct substitutes may include other 40MHz ceramic resonators with similar 4-SMD no-lead packages and 50-Ohm impedance characteristics. Verify pinout compatibility and physical footprint dimensions (2.50mm x 2.00mm) when evaluating alternative suppliers.
