series introduction
# Introduction to the EMK107BJ225KA - T Product Series
## 1. Overview
The EMK107BJ225KA - T product series belongs to the realm of electronic components, specifically capacitors. Capacitors are fundamental building blocks in electronic circuits, and this series offers unique features and performance characteristics that make it suitable for a wide range of applications.
## 2. Product Naming Convention
Let's break down the product code EMK107BJ225KA - T to understand its key specifications:
- **EMK**: This is likely the product family or series identifier assigned by the manufacturer. It represents a specific line of capacitors with certain design and performance traits.
- **107**: In capacitor coding, this indicates the capacitance value. The first two digits (10) are the significant figures, and the third digit (7) is the multiplier. Using the formula \(C = \text{significant figures}\times10^{\text{multiplier}}\) (in picofarads), we have \(C=10\times10^{7}\text{ pF}=100000000\text{ pF} = 100\ \mu\text{F}\).
- **B**: This letter often represents the voltage rating of the capacitor. Different letters correspond to different voltage levels as per the manufacturer's coding system.
- **J**: It typically indicates the tolerance of the capacitor. In this case, a 'J' usually means a tolerance of ±5%.
- **225**: This might be an additional internal code related to the product's specific design, manufacturing batch, or other non - standard characteristics.
- **KA**: Could be a code for specific features such as the type of dielectric material, construction style, or other unique properties of the capacitor.
- **T**: This may represent a packaging type or a specific version of the product within the series.
## 3. Electrical Characteristics
### Capacitance
As calculated from the naming convention, the nominal capacitance of the EMK107BJ225KA - T series is \(100\ \mu\text{F}\). This capacitance value is crucial as it determines the amount of electrical charge the capacitor can store. In circuits, it affects functions such as filtering, coupling, and energy storage. For example, in a power supply filtering circuit, a capacitor with a large capacitance like this can smooth out the DC voltage by storing and releasing electrical energy to reduce voltage ripple.
### Voltage Rating
The voltage rating indicated by the 'B' in the product code is an important parameter. It specifies the maximum voltage that the capacitor can safely withstand without experiencing breakdown or damage. Exceeding this voltage can lead to the failure of the capacitor, which may cause malfunctions in the entire electronic circuit.
### Tolerance
With a tolerance of ±5%, the actual capacitance of the EMK107BJ225KA - T capacitors will be within the range of \(95\ \mu\text{F}\) to \(105\ \mu\text{F}\). This level of precision is important in applications where accurate capacitance values are required, such as in oscillator circuits where the frequency of oscillation is dependent on the capacitance value.
### Temperature Coefficient
The temperature coefficient of the capacitor describes how its capacitance changes with temperature. A stable temperature coefficient is desirable in applications where the operating temperature may vary. The EMK107BJ225KA - T series is designed to have a relatively stable capacitance over a certain temperature range, ensuring consistent performance in different environmental conditions.
