Hello, Please ask a question about LP4040R-R82M Datasheet
# Example questions:
➢ What is the maximum dc resistance, in mohms, for the inductors in the lp4040r series?
➢ What are the different series of surface mount power inductors mentioned in the text?
➢ What is the inductance range, in µh, for the lp5035r series?
Okay, I've analyzed the provided text. It appears to be a data sheet or specification sheet for a series of surface mount power inductors, specifically from the LP4040R, LP5035R, LP5050R, and LP5064R series.
Here's a breakdown of the information, organized into categories:
1. Series and Part Numbering:
️· Series: LP4040R, LP5035R, LP5050R, LP5064R
️· The text implies part numbers are formed by combining a series prefix (e.g., LP4040) with a suffix indicating a specific value or characteristic (e.g., "-R", "-R36", etc.).
2. Physical Characteristics:
️· Actual Size (Max): The physical dimensions are related to the part number, the dimension is in mm
️· LP4040R: 11.5mm
️· LP5035R: 13.7mm
3. Electrical Characteristics:
️· Inductance (µH): This is the primary characteristic. The list of numbers like "36", "45", "56," and others suggests inductance values in microhenries (µH).
️· ±20% @ 100 kHz: Indicates the inductance tolerance is ±20% at a frequency of 100 kHz. This is a crucial specification for circuit design.
️· DC Resistance (mOhms): This is the DC resistance of the inductor, measured in milliohms (mOhms). Lower DC resistance is generally better for efficiency.
️· Current Rating (A DC): This is the maximum DC current the inductor can handle without excessive heating or performance degradation.
️· Incremental Current (A): Likely refers to the current at which the inductor's saturation begins to impact its inductance.
4. Specific Part Suffixes (Examples):
The text highlights some suffixes, which I believe indicate specific inductance values or characteristics:
️· -R36: Likely means an inductance value around 36 µH.
️· -R45: Likely means an inductance value around 45 µH.
️· -R56: Likely means an inductance value around 56 µH.
️· The list of suffixes continues indicating a range of values
In essence, this document provides a detailed specification for a family of power inductors, allowing engineers to select the appropriate inductor for their specific application based on inductance, current handling, DC resistance, and physical size requirements.
If you have any specific questions about a particular part number or characteristic, feel free to ask!
