(25PCS) 1.01k100 Polyester Film Yellow colour Capacitor

​101 (101k): Its value is 100 pF (Picofarad).

K: This means it has a tolerance (error margin) of +/- 10%.

100: It can handle a load of up to 100 volts.

These capacitors are like the “short soldiers” in the capacitor world, serving to clean up signals.

Where is it used? (Main Examples)

These capacitors are not for dissipating excess power, but for controlling signals:

Audio Circuits (Music Systems):

Used in speakers or amplifiers to reduce “noise” and clarify sound.

Example: Inside your home theater or old radios.

Radio and TV Receivers:

To filter radio signals so that the correct station can be picked up.

LED Bulb Drivers:

Used in today’s inexpensive LED bulbs or tube-light circuits to slightly stabilize the voltage.

Fan Regulators:

Small polyester capacitors play a role in the speed control circuits of electronic fan regulators.

Coupling and Decoupling:

These capacitors are used when only an AC signal needs to be passed from one part of the circuit to another and DC current needs to be blocked.
