**TYPES OF CAPACITORS** **INTRODUCTION** Capacitors is one of mostly used component in electronic circuit design. It available at different ratings it consists of two metal plates separated by non-conducting substances, or dielectric, the unit of capacitance is farads \[F\]. It is often storage depots for analog signals and digital data.. **LEARNING** **OUTCOMES** - Identify the types of capacitor and applications. - Familiarize the capacitance of capacitor and voltage ratings. - Decoding the values of ceramic and mylar capacitors. - Solving series and parallel capacitor. - Testing the capacitor using ohmmeter to determine. If the capacitor is open shorted or partially damage. **ACTIVITY** Identify the type of capacitor shown below. **1**. **2**. **3**. **4**. **5.** **LEARNING** **CONTENT** A capacitor is an electronic component that stores and release electrical energy.it consists of two conductive plates separated by an insulting material called a dielectric. When a voltage is applied, the capacitor stores energy in an electric field which can be released when needed capacitors come in various types, including ceramic, electrolytic and film capacitor each designed for specific applications. Capacitors are essential components in electronics. playing a crucial role in energy storage, voltage regulation and signal processing. They stabilize power supplies by filtering out noise and smoothing voltage fluctuations, ensuring the reliable operation of electronics devices. in circuits, capacitors are used to couple and decouple signals allowing the passage of AC while blocking DC, which is vital in signal processing and communication systems additionally, they are integral to timing the passage and frequency applications, such as in locks and radios where they help control oscillations and tune frequencies. Overall, capacitors are indispensable for the efficient and stable functioning of countless electronic system. **TYPES OF CAPACITORS** **1**. **Film Capacitor** The film capacitor are physically larger and more expensive, they are not polarized.it can be used in AC voltage applications, and they have much more stable electrical parameters. Dependence of capacitance and dissipation factor. **2. Ceramic Capacitor** Ceramic Capacitor are used in high frequency circuits such as audio to RF. Also, ceramic capacitors are the best choice for high frequency compensation in audio circuits these are also called as disc capacitors. They are made by coating two sides of a small porcelain or ceramic disc with silver and are then stacked together to make a capacitor. One can make both low capacitances and high capacitances in ceramic capacitors. **3. Electrolytic Capacitor** It is most prevalently used capacitors which have a wide tolerance capacity. Electrolytic capacitors are available with working voltages up to about 500V. there are two types of electrolytic capacitor, tantalum and aluminum in common tantalums capacitor have ordinally better exhibition, higher value. The dielectric properties of tantalum oxide is much superior to those of aluminum oxide.it has an easier leakage current and better capacitance strength which makes them suitable for obstructing, decoupling, filtering applications. the thickness of the aluminum oxide film and heightened breakdowns voltages gives the capacitors exceptional. **4. Variables Capacitor** A Variables capacitor is one whose capacitance may be intentionally and repeatedly changed mechanically. This type of capacitors utilized to set frequency of reassurance LC circuits to adjust the radio for impedance antenna tuner devices. **5. Fixed Capacitor** Fixed Capacitor can be grouped into two classes as electrolytic and non-electrolytic type. It includes paper, mica, and ceramic capacitors such capacitors have no polarity requirements i.e. they can connect in either direction in a circuit.  **6. Polypropylene Capacitor** Polypropylene capacitor is a kind of capacitor with every stable electric capacity. It is often used in applications requiring very precise capacitances and replace most polypropylene or mica capacitor. **7. Tantalum Capacitor** Tantalum capacitor is an electrolytic capacitor, a passive component of electronic circuit sit of a Apelet of porous tantalum metal.  **8**. **Mica Capacitor** Mica Capacitor are generally used when the design calls for stable, reliable capacitor of relatively small values. They are low-loss capacitor, which allow them to be used at high frequencies, and their value does not change much over time. Mica minerals are very electrically, chemically and mechanically. **9**. **Polyester Capacitor** Polyester capacitor are film capacitor using a dielectric made of the thermoplastic polar polymer material polyethylene terephthalate (PET), trade names or mylar.  **10**. **Paper Capacitor** Paper capacitor is also known as a fixed capacitor in which paper is used as the dielectric material. The amount of electric charge stored by the paper capacitor is fixed. **11**. **Timer Capacitor** Timer capacitors are component that are used to store an electrical charge and are used in timer circuits. a capacitor may be used with a resistor to produce a timer sometimes capacitors are used to smooth a current in a circuit as they can prevent false to try triggering of the other components such as relays.  **12**. **Motor Run Capacitor** Motor Run Capacitor is used in single phase motors o maintain a running torque on an auxiliary coil while the motor is loaded. **EVALUATION** **Arrange the jumble words** 1\.
