AWSZT-32.00CW-T

Overview

The AWSZT-32.00CW-T is a miniature surface-mount ceramic resonator manufactured by Abracon LLC, designed for industrial-grade applications within a temperature range of -25°C to +85°C. Operating at a nominal frequency of 32.00 MHz, this component features a tight frequency tolerance of ±0.2% and a stability of ±0.5%. It utilizes a standard SMD/SMT package with dimensions of 2.5 mm in length, 2.0 mm in width, and 1.2 mm in height. The device incorporates an internal capacitance of 22 pF and exhibits an impedance of 40 Ohms, making it suitable for compact electronic designs requiring precise timing signals.

Feature Summary

• Industrial-grade construction ensures reliable performance across extended temperature ranges from -25°C to +85°C.
• Miniature surface-mount footprint allows for high-density PCB layouts and automated assembly processes.
• Integrated internal capacitance simplifies circuit design by eliminating the need for external load capacitors.

Applications

• Microcontroller clock sources in consumer electronics
• Communication interface timing circuits
• Embedded system oscillator replacements

Procurement Notes

Verify that the specific CW suffix corresponds to the required ±0.2% tolerance specification, as other series variants may differ. Confirm the physical package dimensions match the target PCB footprint before finalizing procurement. Ensure the operating temperature range aligns with the environmental conditions of the end application. Cross-reference the manufacturer part number with authorized distributor catalogs to ensure authenticity and availability.

Selection Notes

Select this component when a tighter frequency tolerance than standard ±0.5% resonators is required for 32 MHz applications. Consider the 2.5 x 2.0 mm package size against available board space constraints. Evaluate the 40 Ohm impedance against the driving circuit requirements of the host microcontroller or logic gate. Verify compatibility with reflow soldering profiles specified in the official datasheet.

Part Context

This model belongs to the AWSZT-CW series of low-cost, miniature ceramic resonators from Abracon. It serves as a cost-effective alternative to quartz crystals in applications where moderate frequency accuracy suffices but higher precision than standard ±0.5% parts is needed. The series supports various frequencies and package sizes tailored for modern surface-mount manufacturing standards.

Replacement Considerations

Direct substitutes include other 32 MHz ceramic resonators with ±0.2% tolerance and similar 2.5 x 2.0 mm footprints from manufacturers such as Nihon Dempa Kogyo or ECS International. Ensure replacement parts maintain the same 22 pF internal capacitance and 40 Ohm impedance to preserve circuit timing characteristics without redesign.
