A radio noise capacitor, often referred to as a bypass or decoupling capacitor, serves to filter out unwanted noise and interference in radio circuits. It helps stabilize voltage levels by providing a low-impedance path to ground for high-frequency noise, thereby improving signal clarity and overall performance. This component is crucial in maintaining the integrity of audio and RF signals, ensuring that the radio operates efficiently and with minimal distortion.
The radio capacitor typically connects between the radio circuit and the antenna or the tuning circuit. It helps in filtering and tuning by storing and releasing electrical energy, allowing for the selection of specific frequencies. In some designs, capacitors also connect across components like transistors to stabilize signals or across power supply lines to reduce noise. Proper placement is crucial for optimal radio performance.
Gang capacitors are commonly used in radio tuners/receivers. Radio tuners/receivers have formation of LC(inductance and capacitor). Here this circuit has one fixed inductance and capacitor parallel with gang capacitor. Normally gang capacitor used in superhetrodyne receiver.
The capacitor on it's own is of no use, it is always used in an RC or LC configuration normally in audio frequency's the RC is used to filter the noise down to earth where the RC circuit have to resonate at the same frequency as the noise, the lower the frequency the larger the value of the capacitor
Bypass capacitors are used to bypass (shunt) unwanted signals to the ground. A common use is in power supplies where a bypass capacitor is connected in parallel with the main filter capacitor to shunt noise and other high frequency interference to ground which the main capacitor may not be able to do.
An air variable capacitor might have a range of a few picofarads (high voltage units) to several hundred picofarads (in an old AM radio).
Radio Noise Capacitor (RFI suppressor)
I don't think it needs one to work, but sometimes one is installed to cut down on radio noise.
Radio frequency Condensers (Capacitor) is used to reduce or eliminate ignition noise being received by the broadcast radio in the car.

If the heater blower has humming noise when motor is running, first check its capacitor. If the capacitor is fine, then the motor is the problem and may need to be replaced.
Padders are a type of Capacitors which are used at low frequency end of the radio dial.

There is a capacitor of 4.3uf in the charger, due to voltage fluctuation this capacitor usually get destroyed or become weak. there are lipids in capacitor, these lipids do squarrel to make that noise.
