CM0104 Monolithic Capacitor 100nF (0.1µF) 50V Y5V – 5mm Pitch (104)

The CM0104 100nF (0.1µF) 50V Monolithic Ceramic Capacitor is a compact, non-polarised through-hole capacitor designed for decoupling, bypassing, filtering, and noise suppression in electronic circuits. Featuring a Y5V dielectric, ±20% tolerance, and 5mm lead spacing, it provides useful capacitance in a small package. The common 100nF value makes it particularly useful for power supply decoupling around integrated circuits, microcontrollers, and digital electronics. Its radial through-hole construction is ideal for PCB assembly, breadboards, electronic kits, prototyping, and classroom electronics.

Understanding the Capacitor Value

The CM0104 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, while the third digit indicates four additional zeros when expressed in picofarads:
10 + 4 zeros = 100,000pF = 100nF = 0.1µF

What is a Monolithic Ceramic Capacitor?

A monolithic ceramic capacitor uses multiple layers of ceramic dielectric and conductive material within a compact package. This construction allows useful capacitance values to be achieved while maintaining a small physical size.
The CM0104 is non-polarised, meaning there is no positive or negative lead and it can be installed in either direction.

About the Y5V Dielectric

Y5V ceramic capacitors provide relatively high capacitance in a compact package and are commonly used for general-purpose bypassing, decoupling, and filtering.
Their capacitance can vary considerably with temperature and applied voltage, so Y5V capacitors are generally better suited to decoupling and filtering than precision timing, frequency control, or other applications requiring highly stable capacitance.
