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.
