CPT-1667-85T

Alarms, Buzzers, And Sirens Overview

The CPT-1667-85T is a piezoelectric audio transducer buzzer manufactured by Same Sky. It features through-hole mounting with PC pins and operates at a rated voltage of 12 Vp-p. The device produces a sound pressure level of 85 dB at 10 cm distance when driven at 12 V, drawing an operating current of 10 mA. It emits a tone at a frequency of 4 kHz. The physical dimensions are 16.5 mm in diameter and 6.7 mm in height.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric technology for reliable acoustic signaling
• Externally driven design requiring external drive circuitry
• Through-hole termination for standard PCB integration

Alarms, Buzzers, And Sirens Applications

• General purpose audio indication
• Appliance status alerts
• Industrial control panel signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version to confirm electrical parameters, as some sources list varying voltage ratings. Ensure the drive circuit matches the 12 Vp-p requirement. Confirm RoHS compliance status if required for your assembly process. Check lead times as they may vary by distributor.

Alarms, Buzzers, And Sirens Selection Notes

Select this component for applications requiring a simple, externally driven piezo buzzer with through-hole compatibility. It is suitable where a 4 kHz tone is acceptable. Compare against electromagnetic alternatives if lower power consumption or different acoustic profiles are needed. Verify spatial constraints fit the 16.5 mm diameter.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky CPT series of piezoelectric buzzers. These components are designed as passive transducers that require an external oscillator or microcontroller to generate the driving signal. They are commonly used in consumer electronics and industrial equipment for audible feedback.

Alarms, Buzzers, And Sirens Replacement Considerations

CPT-1667-85T is functionally similar to other 12V 85dB piezo buzzers. Verify pinout and dimensional compatibility before substituting with generic equivalents.
