Decoding the 2r2 Inductor Value Datasheet: Your Essential Guide

The 2r2 Inductor Value Datasheet is a crucial document for anyone working with electronic circuits that incorporate inductors. This datasheet provides precise specifications for a specific type of inductor, identified by its inductance value of 2.2 microhenries (µH), often represented as "2r2". Understanding the information within this datasheet is essential for successful circuit design and troubleshooting.

Understanding Your 2r2 Inductor Value Datasheet

At its core, a 2r2 Inductor Value Datasheet is a technical document that outlines the electrical and physical characteristics of a particular inductor with a nominal inductance of 2.2 microhenries. Inductors are passive electronic components that store energy in a magnetic field when an electric current flows through them. They are fundamental building blocks in many electronic applications, including filters, oscillators, power supplies, and resonant circuits.

The datasheet serves as the definitive source of information for a specific 2r2 inductor. It typically includes a range of vital parameters, such as:

• Inductance Tolerance: The acceptable range of variation from the nominal 2.2 µH value.
• DC Resistance (DCR): The resistance of the inductor's coil at direct current, affecting power loss.
• Rated Current: The maximum current the inductor can handle continuously without overheating or performance degradation.
• Q Factor: A measure of the inductor's efficiency, indicating its performance at a specific frequency.
• Self-Resonant Frequency (SRF): The frequency at which the inductor's parasitic capacitance becomes significant, affecting its behavior.
• Operating Temperature Range: The environmental conditions under which the inductor is designed to function reliably.

When designing a circuit, engineers rely heavily on the 2r2 Inductor Value Datasheet to ensure the chosen component meets the performance requirements. For instance, if a circuit needs to filter out specific frequencies, the inductance value and Q factor are critical. If the circuit handles significant current, the rated current becomes paramount to prevent component failure. The datasheet provides the granular details needed for accurate calculations and simulations, ensuring the final product performs as intended. Failing to consult and understand this datasheet can lead to incorrect component selection, circuit malfunction, or even damage to other components.

Consider a scenario where you need to build a power supply filter. The 2r2 Inductor Value Datasheet would inform you about:

1. The precise inductance for effective filtering.
2. How much current the inductor can safely pass from the power source.
3. The component's resistance, which impacts the efficiency of the power supply.

Here's a simplified example of information you might find in a datasheet:

To ensure your projects function correctly, make sure to refer to the specific 2r2 Inductor Value Datasheet provided by the manufacturer of your chosen inductor. This document holds all the critical information you need for successful integration.
