HF41F/12-HST Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the HF41F/12-HST is 3V to 12V, with a typical operating voltage of 9V.
  • To ensure the buzzer is driven correctly, use a square wave signal with a frequency of 2.4 kHz (±10%) and a duty cycle of 50% ±10%. The signal should be applied between the positive terminal (red wire) and the negative terminal (black wire).
  • The maximum current consumption of the HF41F/12-HST is 30mA, but it's recommended to limit the current to 20mA for optimal performance and longevity.
  • The HF41F/12-HST is designed to operate in a temperature range of -20°C to 70°C and humidity up to 80% RH. However, it's recommended to take precautions to prevent moisture ingress and ensure proper ventilation to maintain reliability.
  • The HF41F/12-HST has a through-hole mounting type. Use a screw or adhesive to secure the buzzer to a PCB or a metal surface, ensuring the buzzer is firmly attached and the terminals are not damaged.
