## What is SG3525 In Q hertz?

SG3525 In Q hertz is the essential tool for technicians, hobbyists, and electronics enthusiasts who need to quickly calculate the frequency of the SG3525A integrated circuit. Our app simplifies the process by allowing you to input the values of the key components:

• RT resistor: connected between pins 6 and 12 (Gnd).
• RD resistor: connected between pins 5 and 7.
• CT capacitor: connected between pins 5 and 12 (Gnd).

To get the desired frequency, enter the values for RT (KOhms or Ohms), RD (KOhms or Ohms), and CT (microFarads or nanoFarads), and click Calculate. The app will provide the resulting frequency, which can be measured at pins 11 and 14 (OUT_A and OUT_B) of the SG3525A.

Features:
• User-friendly and intuitive interface.
• Fast and accurate calculations.
• Supports multiple units of measure.
