series introduction
# FLF3215T - 2R2M Product Series Introduction
## 1. Overview
The FLF3215T - 2R2M product series represents a cutting - edge offering in the field of electronic components. Specifically designed to meet the diverse and demanding requirements of modern electronic circuits, these components play a crucial role in ensuring the efficient and stable operation of various electronic devices.
## 2. Product Naming Convention
- **FLF**: This is the brand or product line identifier, which is associated with a reputation for quality and reliability in the electronics industry. It indicates that the product belongs to a specific family of components developed by the manufacturer.
- **3215**: These numbers typically represent the physical dimensions of the component. In this case, it might refer to the length and width of the device in millimeters or some other standardized measurement system. For example, it could imply a size that is optimized for surface - mount technology (SMT) applications, allowing for easy integration onto printed circuit boards (PCBs).
- **T**: This letter may denote a specific type or variant within the product series. It could indicate a particular performance characteristic, such as temperature range, tolerance level, or packaging option.
- **2R2**: This part of the name usually represents the electrical value of the component. In the context of passive components like inductors or resistors, “2R2” might mean a value of 2.2 (the “R” is used to represent the decimal point). For an inductor, it could be 2.2 microhenries (μH), which is a common unit of inductance.
- **M**: The letter “M” often indicates the tolerance of the component. In the electronics industry, “M” typically stands for a tolerance of ±20%. This means that the actual electrical value of the component can vary by up to 20% from the nominal value (in this case, 2.2).
## 3. Key Features
### Electrical Performance
- **Inductance Value**: With a nominal inductance of 2.2 μH, the FLF3215T - 2R2M is suitable for a wide range of applications that require energy storage and filtering in electrical circuits. Inductors are used to oppose changes in current flow, which is essential for smoothing out voltage fluctuations and reducing electromagnetic interference (EMI).
- **Tolerance**: The ±20% tolerance allows for some flexibility in circuit design. While a relatively wide tolerance, it is still acceptable for many general - purpose applications where precise inductance values are not critical. This also helps to keep the cost of the component down compared to components with tighter tolerances.
- **Saturation Current**: The component has a specified saturation current, which is the maximum current at which the inductance value starts to decrease significantly. A high saturation current rating ensures that the inductor can handle large currents without losing its effectiveness, making it suitable for power - related applications.
### Physical Characteristics
- **Compact Size**: The 3215 form factor makes the FLF3215T - 2R2M a space - saving solution for modern electronic devices. As electronic products continue to become smaller and more compact, the ability to use smaller components without sacrificing performance is crucial.
- **Surface - Mount Technology (SMT)**: The component is designed for SMT, which allows for automated assembly on PCBs. SMT components can be placed and soldered quickly and accurately using pick - and - place machines, increasing the efficiency of the manufacturing process and reducing production costs.
### Thermal Performance
- **Low Power Dissipation**: The FLF3215T - 2R2M is designed to have low power dissipation, which means it generates less heat during operation
