TFM-51M

Alarms, Buzzers, And Sirens Overview

The TFM-51M is a piezoelectric buzzer manufactured by East Electronics, designed for through-hole mounting on printed circuit boards. It operates within a supply voltage range of 3V to 15V and typically functions at a nominal voltage of 10V. The device generates an acoustic output with a sound pressure level of approximately 77dB when measured at a distance of 10cm under 10V excitation. Its operating frequency is centered at 4.1kHz, drawing a current of 3mA during continuous operation. The component features PC pin terminations and has a maximum seated height of 8.10mm with a diameter of 22.00mm. It is rated for operation in temperatures ranging from -20°C to 70°C.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix or variant against the manufacturer's official datasheet to ensure exact electrical parameters match the design requirements. Confirm that the through-hole package dimensions align with the target PCB footprint. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the driving circuit can provide the necessary peak current for the specified voltage range without distortion.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a passive piezoelectric buzzer is required for cost-effective audible signaling. The wide voltage range allows flexibility in system design across different power rails. Consider the 4.1kHz frequency response for optimal human hearing sensitivity. Verify that the 77dB SPL meets the ambient noise requirements of the installation environment. Ensure the driver circuitry supports the external drive mode rather than internal oscillator requirements.

Alarms, Buzzers, And Sirens Part Context

The TFM-51M belongs to the East Electronics line of piezoelectric buzzers, which are characterized by their passive operation and robust construction. These components are commonly used in industrial and consumer applications where reliable acoustic signaling is needed. The series typically offers various voltage ratings and sound pressure levels to suit different application constraints while maintaining a standardized form factor for easy integration into existing designs.

Alarms, Buzzers, And Sirens Replacement Considerations

The TFM-51 is a closely related variant within the same product family. Verify if the TFM-51 meets the specific voltage and SPL requirements before substitution. Cross-reference mechanical dimensions to ensure PCB compatibility. Confirm that the electrical characteristics, particularly the resonant frequency and current draw, are acceptable for the intended circuit.
