Handling Notice
- Please don't touch the component with the bare hand, because electrode maybe corroded.
- Avoid excessive pulling lead wire because wire may break or soldering point may come off.
- The circuits utilizes transistor switching. The circuit constants for heft of the transistor are optimally chosen to maintain stable, so please follow it when you design 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 (Vb-p). The end-users must know the facts that the characteristics of frequency may be quite changed in different shapes with the applied various waves, like sine wave, square wave (Vb-p) or the other waves.
- When other voltages are applied than the recommended one, the characteristics of frequency will also be changed.
- Please keep proper distance from strong magnetic fields when storing, transiting and mounting.
Soldering and Mounting
- Please read the HYDZ specification if soldering of the component is needed.
- Washing of the component is not acceptable, because it is not sealed.
- Please do not cover the hole with tape or other obstacles, as this will produce irregular operation.

Frequently Asked Questions
Q
What is the difference between HYG8540D-3027 and HYG8540D-5037?
The main differences lie in their rated voltage and coil resistance. The HYG8540D-3027 operates at a rated voltage of 3Vp-p with a coil resistance of 16±2Ω, while the HYG8540D-5037 operates at 5Vp-p with a coil resistance of 32±4Ω. Both share the same resonant frequency of 2700Hz and sound pressure level of 86dB minimum.
Q
What type of input signal is required to achieve the rated frequency characteristics?
The rated frequency characteristics can only be achieved by applying a 1/2 duty square wave (Vp-p). Using other waveforms such as sine waves or full-duty square waves may significantly alter the frequency response of the magnetic sounder.
Q
What are the recommended operating and storage temperature ranges?
The HYG8540D series is designed to operate within -20°C to +60°C. For storage purposes, a wider range of -30°C to +80°C is acceptable. It is important to keep the component within these ranges to ensure reliable performance and longevity.
Q
Can the HYG8540D magnetic sounder be washed or cleaned after soldering?
No. Washing of the component is not acceptable because it is not sealed. Exposure to liquids during cleaning processes may damage the internal structure and lead to malfunction. Please follow the HYDZ specification for any soldering requirements.
Q
What industries and applications is the HYG8540D series suitable for?
The HYG8540D series is widely applicable across multiple industries, including telecommunications (telephones), consumer electronics (clocks, home appliances, air conditioners, microwave ovens), medical equipment, digital products, toys, notebook computers, and automatic controlling devices.
Q
Does the HYG8540D comply with RoHS environmental protection standards?
Yes, the HYG8540D series complies with RoHS (Restriction of Hazardous Substances) environmental protection regulations, making it suitable for use in products that require compliance with international environmental and safety standards.
