Overview
The Same Sky CPT-1255C-090 is a piezoelectric audio transducer buzzer designed for through-hole mounting. It operates at a rated voltage of 20 V and draws a current of 7 mA. The device produces a single tone at a frequency of 4 kHz with a sound pressure level of 80 dB. Its physical dimensions are 12 mm in diameter and 5.5 mm in height, utilizing solder pin termination.
Feature Summary
- Integrates a piezoelectric element to generate audible alerts via direct electrical drive.
- Features a compact cylindrical form factor suitable for space-constrained printed circuit board layouts.
- Utilizes through-hole solder pin connections for secure mechanical attachment.
Applications
- Industrial control panel status indication
- Household appliance operational feedback
- Electronic equipment alarm signaling
Procurement Notes
Verify the specific suffix codes against manufacturer documentation to confirm exact acoustic and electrical tolerances. Ensure that the procurement channel provides valid traceability records. Confirm that the component meets all relevant environmental compliance standards required for the target deployment region before finalizing orders.
Selection Notes
Select this component when a moderate sound output is required within a restricted vertical profile. The 20 V rating distinguishes it from lower voltage alternatives. Evaluate the through-hole requirement against available PCB footprint constraints. Consider the 4 kHz frequency for optimal human audibility in noisy environments.
Part Context
This part belongs to the CPT series of piezoelectric buzzers manufactured by Same Sky. The series offers various sizes and voltage ratings. This specific model represents a mid-range option balancing size and acoustic output for general-purpose electronic applications.
Replacement Considerations
Cross-reference with other Same Sky CPT models sharing identical 12 mm diameter and through-hole specifications. Verify that substitute parts match the 20 V operating voltage and 4 kHz frequency requirements to ensure functional compatibility without circuit redesign.
