Alarms, Buzzers, And Sirens datasheet and documents for CPT-1985-88-SMT-TR

CPT-1985-88-SMT-TR

Alarms, Buzzers, And Sirens Overview

The CPT-1985-88-SMT-TR is a surface-mount piezoelectric audio transducer manufactured by Same Sky. It features a square footprint measuring 19 mm in length and width, with a height of 8.5 mm. The device operates at a nominal voltage of 12 VDC and draws a current of 38 mA. It produces a sound pressure level of 88 dB when driven at 12 V from a distance of 10 cm. The resonant frequency is specified at 2 kHz. This component is designed for direct soldering to printed circuit boards using surface mount technology pads.

Alarms, Buzzers, And Sirens Feature Summary

Externally driven piezoelectric transducer design
Surface mount solder pad termination for PCB integration
High acoustic output capability for audible alerts

Alarms, Buzzers, And Sirens Applications

Electronic alarm systems requiring high-volume audible warnings
Industrial control panels needing status indication
Consumer appliance safety notification circuits

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific drive circuit requirements against the datasheet specifications before procurement. Ensure the PCB layout accommodates the 19 mm x 19 mm footprint and 8.5 mm height clearance. Confirm that the power supply can deliver the required 38 mA current at 12 VDC during operation. Check for any mechanical interference with adjacent components due to the physical dimensions.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a high-decibel audible indicator is necessary for surface-mount assembly. The 12 V operating voltage suits standard logic-level power rails in industrial and consumer electronics. Consider the 2 kHz frequency response for optimal human hearing sensitivity in alert applications. Evaluate space constraints given the 19 mm square form factor and 8.5 mm profile.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky (formerly CUI Devices) line of externally driven piezo buzzers. These transducers are distinct from self-exciting types as they require an external oscillator or microcontroller signal to generate sound. The product series emphasizes robust acoustic performance in compact surface-mount packages suitable for automated manufacturing processes.
