SMT-0823-S-R

Alarms, Buzzers, And Sirens Overview

The PUI Audio SMT-0823-S-R is an externally driven electromagnetic transducer designed for surface mount technology (SMT) applications. It features a square footprint with gullwing lead terminations for board mounting. The device operates at a resonant frequency of 2.3 kHz and delivers a sound pressure level of 87 dBA. Electrical specifications include a maximum supply voltage of 6 V, a current rating of 90 mA, and an impedance of approximately 15 to 16 ohms. Physical dimensions are 8.5 mm in length and width, with a depth of 4 mm. The component supports an operating temperature range from -40°C to +70°C or +85°C depending on specific environmental ratings.

Alarms, Buzzers, And Sirens Feature Summary

• Surface mount electromagnetic transducer design
• Externally driven operation mode
• Gullwing lead termination for PCB integration

Alarms, Buzzers, And Sirens Applications

• Electronic alarm systems
• Audible status indicators
• Consumer electronic devices requiring compact audio output

Alarms, Buzzers, And Sirens Procurement Notes

Verify the exact operating temperature range and impedance values against the manufacturer's official datasheet, as sources indicate variations between +70°C and +85°C maximums. Confirm that the external drive circuitry matches the 90 mA current rating and 6 V maximum voltage limits. Ensure the gullwing package profile aligns with your PCB stencil design and reflow soldering profiles.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a low-profile, surface-mountable audible indicator is required. The 2.3 kHz resonant frequency provides distinct audibility for alert purposes. Consider the 87 dBA output level relative to enclosure attenuation. Verify compatibility with external driving circuits capable of handling the specified current and voltage parameters without exceeding thermal limits.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the PUI Audio SMT series of surface mount transducers. It shares physical form factors with other models in the family but differs in electrical characteristics such as resonant frequency and sensitivity. The SMT-0823-S-R is specifically optimized for applications requiring a balance between acoustic output and minimal board space consumption.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes within the same series include the SMT-0827-TW-3V-R and SMT-0821-T-R, though these differ in resonant frequency and current requirements. Cross-model replacements must be evaluated for mechanical fit and electrical compatibility with existing drive circuits.
