1. Product Overview:

️· Type: SMD (Surface Mount Device) Inductor
️· Series: DR353-1
️· Application: General purpose, designed for various electronic circuits.

2. Key Features:

️· Size: Compact form factor suitable for space-constrained applications. (Specific dimensions are given in the mechanical outline, not directly specified in this document)
️· RoHS Compliant: Meets environmental regulations.
️· Non-RoHS Option: Can be specified without RoHS compliance (using "42-" prefix).

3. Electrical Specifications (Table Breakdown):

The table provides values for the following parameters:

️· Part Number: The unique identifier for each inductor variant.
️· Inductance (L): Measured in μH (microhenries). The range is from 0.82 µH to 560 µH.
️· Tolerance: Indicates how much the actual inductance can vary from the nominal value (either ±10% or ±20%).
️· Frequency (f): Test frequency in MHz (MegaHertz) used for measuring inductance. Several values of frequency are listed, and may have different meanings for various measurements.
️· DCR (DC Resistance): Measured in Ohms (Ω). Represents the internal resistance of the inductor. A lower DCR reduces power loss.
️· Rated Current (I_R): The maximum DC current that the inductor can carry without saturating or experiencing excessive temperature rise. Expressed in Amperes (A).
️· Saturation Current (I_Sat): The current level at which the inductance drops to 30% of its initial value.
️· Q Factor: A measure of inductor efficiency, indicating how well the inductor stores energy versus losing it.
️· Operating Temperature: -40°C to +85°C

4. Mechanical Outline:

️· Detailed mechanical dimensions are provided in a separate section (not extracted in full, but it shows that it is a rectangular shape).

5. Notes:

️· "42-" prefix: Used for specifying non-RoHS compliant parts.
️· Soldering: Terminal finish complies with RoHS requirements, suggesting lead-free soldering capabilities, and should be done according to J-STD-020D.
