Handling Notice
- 1Please don't touch the component with the bare hand, because electrode maybe corroded.
- 2Avoid excessive pulling lead wire because wire may break or soldering point may come off.
- 3The circuits utilizes transistor switching. The circuit constants for heft of the transistor are optimally chosen to maintain stable, so please follow it when you design a circuit.
- 4Magnetic sounders are driven by an input frequency. The given frequency characteristics can be obtained only when applying 1/2 duty square wave (Vb-p). The end-users must know the facts that the characteristics of frequency may be quite change in different shapes with the applied various waves, like sine wave, square wave (Vb-p) or the other waves.
- 5When other voltage are applied than recommended one, the characteristics of frequency will be also changed.
- 6Please keep proper distance for strong magnetic field when you storing, transiting and mounting.
Soldering and Mounting
- 1Please read of HYDZ specification, if soldering component is needed.
- 2Washing of the component is not acceptable, because it is not scaled.
- 3Please do not cover the hole with tape or other obstacles, as this will produce irregular operation.

Frequently Asked Questions (FAQ)
Q What is the difference between HYG9045A-03 and HYG9045A-05?
A The main difference lies in the rated voltage and coil resistance. The HYG9045A-03 operates at a rated voltage of 3 Vp-p with a coil resistance of 16±4Ω, while the HYG9045A-05 operates at 5 Vp-p with a coil resistance of 30±6Ω. Both share the same resonant frequency, current consumption, and sound pressure level specifications.
Q What type of input signal should be used to drive the HYG9045A magnetic sounder?
A The HYG9045A must be driven with a 1/2 duty square wave (Vp-p) at the rated frequency. Using other waveforms such as sine waves or full-duty square waves may significantly alter the frequency characteristics and sound output performance.
Q What is the resonant frequency of the HYG9045A buzzer?
A The resonant frequency of the HYG9045A is 2731 Hz for both the -03 and -05 variants. The minimum sound pressure level achieved at this frequency is 80 dB measured at 10 cm under rated voltage conditions.
Q Is the HYG9045A compliant with RoHS environmental regulations?
A Yes, the HYG9045A is fully compliant with the RoHS (Restriction of Hazardous Substances) directive. The housing is made of LCP (black) material and the leaded pins are brass plated, all meeting environmental protection standards.
Q What are the storage and operating temperature ranges for the HYG9045A?
A The HYG9045A has an operating temperature range of -20°C to +60°C, suitable for most indoor and moderate outdoor environments. For storage, the acceptable range is wider, from -30°C to +80°C, ensuring durability during transportation and warehousing.
Q Can the HYG9045A be washed after soldering, and what precautions should be taken during mounting?
A No, washing the component after soldering is not acceptable as it is not sealed. During mounting, ensure the sound hole is never covered with tape or any obstacles, as this will cause irregular operation. Always refer to the HYDZ specification before performing any soldering, and avoid applying voltage levels outside the recommended operating range.
