TP094003-1

Alarms, Buzzers, And Sirens Overview

The TP094003-1 is a piezoelectric transducer manufactured by DB Unlimited. It features an externally driven design with gullwing lead termination for surface mount installation. The component operates at a resonant frequency of 4 kHz and delivers a sound pressure level of 65 dB when driven at 3 V. Rated voltage ranges from 1 to 25 V, with a maximum current consumption of 3 mA. The physical dimensions are 9 mm in length and width, with a height of 1.9 mm. It functions within a temperature range of -20°C to +70°C.

Alarms, Buzzers, And Sirens Feature Summary

Extremely compact package size optimized for space-constrained designs
Low current consumption suitable for battery-powered applications
High performance-to-size ratio for efficient sound emission

Alarms, Buzzers, And Sirens Applications

Portable electronic devices requiring small form factor alarms
Battery-operated consumer electronics
Embedded systems with limited power budgets

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet revision and mechanical drawing details before integration. Confirm that the external driver circuitry matches the specified peak-to-peak signal requirements. Ensure the operating voltage remains within the 1 to 25 V range to prevent damage. Check compatibility with standard SMT reflow profiles for gullwing leads.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when minimal footprint and low power draw are critical constraints. The 4 kHz frequency provides clear audible indication without excessive volume. Consider the external drive requirement, as it lacks internal oscillator circuitry. Evaluate thermal limits if the application environment exceeds standard room temperatures.

Alarms, Buzzers, And Sirens Part Context

This part belongs to DB Unlimited's line of piezoelectric transducers designed for high-density mounting. It differs from larger rectangular speakers by utilizing a circular active element housed in a tiny square package. The technology relies on piezoelectric materials rather than magnetic coils, enabling thinner profiles compared to traditional dynamic drivers.
