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, and may be degraded in solderability due to storage in a chemical atmosphere.
Frequently Asked Questions
Q
What is the resonance frequency of the HYR-2304 buzzer?
The HYR-2304 has a resonance frequency of 4.0 ± 0.3 KHz, making it suitable for a wide range of alarm and notification applications requiring a consistent audible tone.
Q
What is the minimum sound output of the HYR-2304?
The minimum sound output is 85 dB measured at 10 cm distance, at 5Vp-p and 4.8KHz. This ensures a clearly audible alert in most environments.
Q
What are the operating and storage temperature ranges for the HYR-2304?
The HYR-2304 operates within a temperature range of -20°C to +70°C. For storage, the acceptable range is -30°C to +80°C. For long-term storage, it is recommended to keep the temperature between -10°C and +40°C.
Q
How long can the HYR-2304 be stored before use?
The shelf life is six months from the delivery date when stored in a sealed, unopened package under recommended conditions. Products stored beyond six months should be checked for solderability and characteristics before use.
Q
What precautions should be taken when handling the HYR-2304?
Avoid applying mechanical stress beyond specifications, protect the circuit from surge voltage caused by shock or temperature changes, and do not pull the lead wire excessively to prevent wire breakage or solder joint failure.
Q
Can the HYR-2304 be stored in environments with chemical exposure?
No. The HYR-2304 should not be stored in chemical atmospheres containing acids, alkali, bases, organic gases, or sulfides. Exposure to such environments may degrade the product's performance and solderability.
