⚠️ Handling Notice
- Please don't touch the component with bare hands, because the electrode may be corroded.
- Avoid excessive pulling of lead wire because wire may break or soldering point may come off.
- The circuit utilizes transistor switching. The circuit constants for the transistor are optimally chosen to maintain stable operation, so please follow these guidelines when designing a circuit.
- Magnetic sounders are driven by an input frequency. The given frequency characteristics can be obtained only when applying 1/2 duty square wave (Vp-p). End-users must be aware that the 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 keep a proper distance from strong magnetic fields during storage, transit, and mounting.
🔩 Soldering and Mounting
- Please read the HYDZ specification before soldering the component.
- 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 produce irregular operation.
