Manufacturer: multicomp
# Introduction to the MC0805B334K160CT Product Series
## 1. Overview
The MC0805B334K160CT product series belongs to the realm of electronic components, specifically surface - mount capacitors. These capacitors play a crucial role in a wide range of electronic circuits, providing functions such as energy storage, filtering, coupling, and decoupling. The "MC" likely represents the manufacturer's product line identifier, while the subsequent alphanumeric code contains specific information about the capacitor's characteristics.
## 2. Physical Characteristics
### Package Size
The "0805" in the model number indicates the package size of the capacitor. In the imperial measurement system commonly used in the electronics industry, an 0805 package has dimensions of approximately 0.08 inches (2.032 mm) in length and 0.05 inches (1.27 mm) in width. This relatively small size makes it suitable for use in compact electronic devices where space is at a premium, such as mobile phones, tablets, and wearable devices.
### Construction
These capacitors are typically constructed using ceramic materials. Ceramic capacitors are known for their high dielectric constant, which allows them to store a relatively large amount of charge in a small volume. The construction also involves metal electrodes on either side of the ceramic dielectric, which are connected to the external terminals for electrical connection within the circuit.
## 3. Electrical Characteristics
### Capacitance
The "334" in the model number represents the capacitance value of the capacitor. In the standard capacitor coding system, the first two digits (33) are the significant figures, and the third digit (4) is the multiplier. So, the capacitance value is calculated as \(33\times10^{4}\) picofarads (\(pF\)). This equates to \(330000 pF\) or \(0.33\) microfarads (\(\mu F\)). This capacitance value is suitable for a variety of applications, such as filtering out low - frequency noise in power supply circuits or coupling signals between different stages of an amplifier.
### Tolerance
The "K" indicates the tolerance of the capacitance value. A "K" tolerance means that the actual capacitance of the capacitor can vary by ±10% from the nominal value. For the MC0805B334K160CT, the actual capacitance can range from \(0.33\times(1 - 0.1)=0.297\ \mu F\) to \(0.33\times(1 + 0.1)=0.363\ \mu F\). This tolerance is important in applications where precise capacitance values are required, as it affects the performance of the circuit.
### Voltage Rating
The "160" represents the voltage rating of the capacitor, which is 160 volts. This means that the capacitor can safely operate in a circuit where the maximum voltage across it does not exceed 160 volts. Exceeding this voltage rating can lead to dielectric breakdown, which may damage the capacitor and cause the circuit to malfunction.
### Temperature Coefficient
Although not explicitly stated in the model number, ceramic capacitors in this series usually have a specific temperature coefficient. The temperature coefficient describes how the capacitance value changes with temperature. Different ceramic materials have different temperature coefficients, and the choice of temperature coefficient depends on the application requirements. For example, in applications where the temperature can vary significantly, a capacitor with a low - temperature coefficient may be preferred to ensure stable performance.
