Mini L-c Power LC Filter Module Jhemcu 3A 3-20V

The Mini L-c Power LC Filter Module Jhemcu 3A 3-20V is a compact and efficient power filter designed to eliminate electrical noise and interference from DC power supplies, especially in sensitive electronic applications. By combining high-quality inductors and capacitors, this LC filter effectively suppresses high-frequency noise and disturbances that can degrade video or audio signals in embedded systems.

Application Areas:

• FPV (First Person View) systems for drones and quadcopters
• RC modeling (remote-controlled cars, planes, boats)
• Battery-powered robots where motors and sensitive electronics share the same power source
• Embedded projects requiring clean power for cameras, video transmitters, audio modules, or microcontrollers

Example Projects Where This Module Is Used:

• FPV drone: Eliminating video noise by powering the camera and video transmitter through the LC filter.
• Mobile robot: Reducing interference from motors affecting sensors or communication modules.
• Arduino or Raspberry Pi embedded systems powered by batteries, where sensitive modules (cameras, radio modules) share power with noise-generating components.

The module supports up to 3A current and input voltages from 3 to 20V, with minimal voltage drop and reverse polarity protection. It is especially recommended for setups where a single battery powers both motors and sensitive electronics, ensuring a clean and stable power supply.
