CPT-1203-78-SMT-TR

Alarms, Buzzers, And Sirens Overview

The CPT-1203-78-SMT-TR is a surface-mount piezoelectric audio transducer manufactured by Same Sky. It features a compact rectangular footprint measuring 12 mm in length, 12 mm in width, and 3 mm in height. The device operates at a rated voltage of 5 V with a peak-to-peak drive requirement of 5 Vp-p. It produces a sound pressure level of 78 dB at a resonant frequency of 4 kHz. The unit draws a current of 5 mA during operation and utilizes SMD/SMT termination for PCB integration.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric transduction mechanism for reliable acoustic signal generation
• Surface mount design optimized for automated assembly processes
• Compact low-profile form factor suitable for space-constrained enclosures

Alarms, Buzzers, And Sirens Applications

• Electronic equipment status indicators
• Consumer appliance alert systems
• Industrial control panel signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix TR against official manufacturer documentation to confirm reel packaging specifications. Ensure the operating voltage aligns with system requirements as the component is rated for 5 V. Cross-reference the datasheet for precise mechanical tolerances and soldering thermal profiles to guarantee proper surface mount attachment.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile surface mount buzzer is required for 5 V logic circuits. The 78 dB output provides adequate audibility for general status indication. Consider the 4 kHz frequency response for standard alert tones. Verify that the 12x12 mm footprint matches the target PCB layout constraints.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Same Sky CPT series of piezoelectric buzzers. The series offers various mounting styles and acoustic outputs. The CPT-1203 variant specifically denotes the 12 mm square housing size. The -SMT- suffix indicates surface mount technology compatibility, distinguishing it from through-hole alternatives within the product family.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult official substitution guides for compatible equivalents. Verify pinout compatibility and acoustic performance metrics before replacing.
