    Notice (Handling)
    • 1 The component may be damaged if mechanical stress exceeding specifications is applied.
    • 2 Take care to protect the operating circuit from surge voltage resulting from excessive force, falling, shock or temperature change.
    • 3 Avoid excessive pulling of the lead wire because the wire may break or the soldering point come off.
    Notice (Storage and Operating Condition)
    1. Product Storage Condition

    Please store the products in a room where the temperature/humidity is stable and avoid places where there are large temperature changes.

    Please store the products under the following conditions:

    🌡️ Temperature: -10 to +40°C

    💧 Humidity: 15 to 85% R.H.

    2. Expiration Date on Storage

    Expiration date (shelf life) of the products is six months after delivery under the conditions of a sealed and unopened package. Please use the products within six months after delivery. If you store the products for a long time (more than six months), use carefully because the products may be degraded in solderability due to storage under poor conditions.

    Please confirm solderability and characteristics for the products regularly.

    3. Notice on Product Storage

    Please do not store the products in a chemical atmosphere (Acids, Alkali, Bases, Organic gas, Sulfides and so on), because the characteristics may be reduced in quality, may be degraded in solderability due to storage in a chemical atmosphere.

    Frequently Asked Questions
    Q1 What is the operating voltage range of the HYD-3020 buzzer?
    The HYD-3020 buzzer supports an operating voltage range of 5V to 24V DC, with a rated voltage of 12V DC. This wide voltage range makes it compatible with a variety of electronic systems and applications.
    Q2 What is the sound output level of the HYD-3020 at 10cm distance?
    The HYD-3020 delivers a sound output of ≥100 dB measured at a distance of 10cm. This makes it suitable for alarm systems, alert devices, and other applications requiring a loud audible signal.
    Q3 What temperature range can the HYD-3020 operate in?
    The HYD-3020 buzzer is designed to operate reliably within a temperature range of -20°C to +80°C, making it suitable for both indoor and outdoor environments with varying temperature conditions.
    Q4 How should the HYD-3020 be stored to ensure longevity?
    Store the HYD-3020 in a stable environment with temperatures between -10°C and +40°C, and humidity between 15% and 85% R.H. Avoid chemical atmospheres including acids, alkalis, organic gases, and sulfides, as these can degrade product quality and solderability.
    Q5 What is the shelf life of the HYD-3020 buzzer?
    The shelf life of the HYD-3020 is six months from the delivery date when stored in a sealed and unopened package under the recommended storage conditions. Products stored beyond six months should be carefully inspected for solderability before use.
    Q6 What precautions should be taken when handling the HYD-3020?
    Avoid applying mechanical stress beyond the specified limits, as this may damage the component. Protect the circuit from surge voltage caused by excessive force, falling, or sudden temperature changes. Also, do not excessively pull the lead wire, as this may cause wire breakage or detachment of the soldering point.
