SMT-1341-T-HT-2

Alarms, Buzzers, And Sirens Overview

The SMT-1341-T-HT-2 is a piezoelectric transducer manufactured by PUI Audio. It features a square footprint of 13mm x 13mm with a low profile height of 2.5mm, designed for surface mount technology (SMT) applications. The device operates at a self-resonant frequency of 4.1 kHz and delivers a sound pressure level of 85 dBA. It requires a minimum supply voltage of 1V AC and draws a current of 3mA at 5V. The component utilizes solder pads for termination and is suitable for environments ranging from -40°C to +105°C.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix HT-2 against official datasheets to confirm high-temperature rating and acoustic specifications. Ensure PCB land patterns match the 13mm x 13mm dimensions and 2.5mm height constraints. Confirm solder pad compatibility with chosen reflow profiles. Cross-reference RoHS compliance status with current manufacturer declarations before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when low profile and surface mount capabilities are required for piezoelectric signaling. Consider the 85 dBA output and 4.1 kHz resonant frequency for audibility requirements. Evaluate the 1V AC minimum operating voltage against system power rails. Assess thermal stability needs against the specified operating temperature range for environmental suitability.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the SMT-13 series of piezoelectric transducers from PUI Audio. The series focuses on compact, surface-mount solutions for audio signaling. The SMT-1341 variant specifically denotes the 13mm square form factor. The HT suffix typically indicates enhanced thermal or acoustic characteristics within the product line.

Alarms, Buzzers, And Sirens Replacement Considerations

The SMT-1341-T-2-R is a related variant within the same series. Verify if the lower SPL rating and different packaging format meet application requirements. Check electrical parameters against the original specification to ensure functional equivalence.
