⚠️ Handling Notice
- 1Please don't touch the component with the bare hand, because electrode may be corroded.
- 2Avoid excessive pulling of the lead wire because the wire may break or the soldering point may come off.
- 3The circuit utilizes transistor switching. The circuit constants for the transistor are optimally chosen to maintain stable operation, so please follow them when designing a circuit.
- 4Magnetic 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). The characteristics of frequency may change significantly with different waveforms such as sine wave, square wave (Vp-p), or other waves.
- 5When voltages other than the recommended ones are applied, the frequency characteristics will also change.
- 6Please keep a proper distance from strong magnetic fields when storing, transporting, and mounting.
🔩 Soldering and Mounting
- 1Please read the HYDZ specification if soldering of the component is needed.
- 2Washing of the component is not acceptable, because it is not sealed.
- 3Please do not cover the hole with tape or other obstacles, as this will produce irregular operation.
