Notice — Soldering and Mounting
1 Mounting
When mounting a pin terminal type of product to the printed circuit board, please insert the pin terminal along the hole of the board. If the product is pressed so that the terminal is not in the hole, the pin terminal would be pushed into the inside of the product and the sounds might become unstable.
2 Double-sided Through-hole Board
Please avoid using a double-sided through-hole board. If the melted solder touched the base of a pin terminal, a part of the plastic case would melt and the sounds might become unstable.
3 Soldering Conditions
(1) Flow soldering conditions for pin terminal type:
· Temperature: within 260°C ± 5°C
· Time: within 10 ± 1 sec.
· Soldering part is the lead terminals excluding 1.5mm from product body.
· Temperature: within 260°C ± 5°C
· Time: within 10 ± 1 sec.
· Soldering part is the lead terminals excluding 1.5mm from product body.
(2) Please do not store the products directly on the floor without anything under them to avoid damp places and/or dusty places.
(3) Please do not store the product in places such as in a damp heated place or any place exposed to direct sunlight or excessive vibration.
(4) Please use the products immediately after the package is opened, because the characteristics may be reduced in quality, and/or be degraded in solderability due to storage under poor conditions.
(5) Please be sure to consult with our sales representative or engineer whenever the products are to be used in conditions not listed above.
4 Operating Environment
This product is designed for application in an ordinary environment (normal room temperature, humidity and atmospheric pressure). Do not use the products in a chemical atmosphere such as chlorine gas, acid or sulfide gas. Characteristics might degrade by a chemical reaction with the material used in products.
(2) Soldering condition by soldering iron for pin terminal type:
· Temperature: within 350 ± 5°C
· Time: within 3.0 ± 0.5 sec.
· Soldering part is the lead terminals excluding 1.5mm from product body.
· Temperature: within 350 ± 5°C
· Time: within 3.0 ± 0.5 sec.
· Soldering part is the lead terminals excluding 1.5mm from product body.
(3) Reflow soldering condition for surface mounting type:
· Temperature profile: Fig. 1
· Number of times: Within 2 maximum
· Temperature profile: Fig. 1
· Number of times: Within 2 maximum
5 Washing
Please avoid washing, since this product is not a sealed structure.
6 After Mounting the Product
(1) If the product is floating from the printed circuit board, please do not push it. When pressing, the pin terminal is pushed inside the product and the sounds might become unstable.
(2) Please do not apply force (shock) to the product. If force is applied, the case might come off.
(3) If the case comes off, please do not reassemble. Even if it seems to have returned to the original, the sounds might become unstable.
(4) Please do not blow air onto the product directly. Blown air applies force to the piezoelectric diaphragm through the sound emission hole; cracks could occur and then the sounds could become unstable. In addition, there is a possibility that the case could come off.
Notice — Handling
1. Piezoelectric ceramic is used in this product. Please use care in handling, because ceramic is broken when excessive force is applied.
2. Please do not apply force to the piezoelectric diaphragm from the sound emission hole. If applying force, cracks occur and the sounds might become unstable.
3. Please do not drop the product or apply shock or temperature change to it. If so, the LSI might be destroyed by the charge (surge voltage) generated. The figure below shows an example driving circuit using a zener diode.
Notice — Driving
1. Ag migration might occur if DC voltage is applied to the product under a high humidity environment. Please avoid using it under high humidity and design the circuit not to apply DC voltage.
2. When driving the product by IC, please insert the resistance of 1 to 2kΩ in series. The purpose is to protect the IC and to obtain stable sound. (Please see Fig. 2a). Inserting a diode in parallel to the product has the same effect. (Please see Fig. 3b)
3. Flux or Coating Agent, etc., Various Solvents — It is possible for a liquid solvent to penetrate inside the product, since this product is not a sealed structure. If a liquid penetrated inside and attached to the piezoelectric diaphragm, its vibration could be inhibited. If attaching to an electrical junction, the electric connection might fail. To prevent sound instability, please do not allow liquid to penetrate inside the product.
Frequently Asked Questions (FAQ)
Q What is the operating voltage range of the HYG1325A piezoelectric sounder?
The HYG1325A supports a maximum operating voltage of 25Vp-p. It is important to note that Vp-p equals 1/2 duty square wave, and typical performance measurements are taken at 5Vp-p.
Q What is the resonant frequency of the HYG1325A, and how does it affect performance?
The resonant frequency is 4000 ± 300 Hz. Operating the device near its resonant frequency (4.1KHz) maximizes sound pressure output. Driving it significantly outside this range may result in reduced sound pressure levels.
Q Can the HYG1325A be washed after soldering?
No. Washing is not recommended because the HYG1325A is not a sealed structure. Liquid can penetrate inside the product, potentially inhibiting the vibration of the piezoelectric diaphragm or causing electrical connection failures.
Q What precautions should be taken when driving the HYG1325A with an IC?
When driving with an IC, it is recommended to insert a series resistance of 1 to 2kΩ to protect the IC and ensure stable sound output. Alternatively, inserting a diode in parallel to the product achieves a similar protective effect. Also, avoid applying DC voltage under high humidity to prevent Ag migration.
Q What are the recommended storage conditions for the HYG1325A?
The product should be stored at temperatures between -30°C and +80°C. Avoid storing in damp, dusty, or heated environments, and keep away from direct sunlight or excessive vibration. Products should be used promptly after opening the package to maintain optimal solderability and performance.
Q What are the reflow soldering conditions for the surface mounting version of this product?
For surface mounting type, reflow soldering should follow the temperature profile specified in Fig. 1, and the number of reflow passes must not exceed 2 times. For pin terminal types using flow soldering, the temperature should be within 260°C ± 5°C for within 10 ± 1 seconds.
