CP0104 0.1µF (100nF) 104 100V MKT Capacitor

The CP0104 0.1µF (100nF) 100V MKT Capacitor is a reliable metallised polyester film capacitor designed for filtering, coupling, decoupling, timing, bypassing, and noise suppression in electronic circuits. With a 100V rating and ±10% tolerance, it is a versatile general-purpose component suitable for power supplies, audio circuits, signal processing, electronic kits, and control circuits. Its non-polarised construction allows installation in either direction, while the through-hole format makes it ideal for PCB assembly, prototyping, repairs, and classroom electronics.

Understanding the Capacitor Value

The CP0104 capacitance can be expressed in several equivalent ways:
• 0.1µF
• 100nF
• 100,000pF
The 104 marking is a standard capacitor value code. The first two digits represent 10 and the third digit indicates four additional zeros when expressed in picofarads, giving 100,000pF, 100nF or 0.1µF.

What is an MKT Capacitor?

MKT capacitors use metallised polyester film as the dielectric construction. They provide dependable general-purpose performance and are widely used in electronic circuits where stable capacitance, durability, and non-polarised operation are required. Unlike electrolytic capacitors, an MKT capacitor does not have positive and negative leads and can therefore be installed in either direction.
