Handling Notice
- Please don't touch the component with the bare hand, because the electrode may be corroded.
- Avoid excessive pulling of the lead wire because the wire may break or the soldering point may come off.
- The circuit utilizes transistor switching. The circuit constants for the transistor are optimally chosen to maintain stability, so please follow the guidelines when designing a circuit.
- Magnetic sounders are driven by an input frequency. The given frequency characteristics can be obtained only when applying a 1/2 duty square wave (Vp-p). End-users must be aware that frequency characteristics may change significantly with different waveforms such as sine wave, square wave (Vp-p), or other wave types.
- When voltages other than the recommended voltage are applied, the frequency characteristics will also change.
- Please maintain a proper distance from strong magnetic fields during storage, transit, and mounting.
Soldering and Mounting
- Please refer to the HYDZ specification if soldering of the component is required.
- Washing of the component is not acceptable, as it is not sealed.
- Please do not cover the hole with tape or other obstacles, as this will cause irregular operation.

Frequently Asked Questions (FAQ)
QWhat is the rated voltage and operating voltage range of the HYG9025A?
The rated voltage of the HYG9025A is 3 Vp-p, with an operating voltage range of 2~4 Vp-p. It is important to apply the correct voltage to maintain stable frequency characteristics and avoid performance deviation.
QWhat type of input signal should be used to drive the HYG9025A?
The HYG9025A should be driven using a 1/2 duty square wave (Vp-p) at the rated frequency of 2731 Hz. Using other waveforms such as sine waves or full-duty square waves may significantly alter the frequency and sound characteristics.
QWhat is the sound pressure level and current consumption of this buzzer?
At rated voltage, the HYG9025A produces a minimum sound pressure level of 80 dB measured at 10 cm. The maximum current consumption is 90 mA at rated voltage.
QWhat are the storage and operating temperature ranges for the HYG9025A?
The operating temperature range is -20°C to +60°C, and the storage temperature range is -30°C to +80°C. Operating or storing the component outside these ranges may cause damage or performance degradation.
QCan the HYG9025A be washed or cleaned after soldering?
No. Washing or cleaning of the HYG9025A is not acceptable because it is not sealed. Exposure to cleaning liquids may damage the internal components and lead to malfunction.
QWhat are the typical applications for the HYG9025A magnetic buzzer?
The HYG9025A is widely used in telephones, clocks, medical equipment, digital products, toys, office equipment, notebook computers, microwave ovens, air conditioners, home electronics, and automatic controlling devices.
