The 82473C is a fixed inductor manufactured by Murata Power Solutions Inc. Fixed inductors are passive electronic components that store energy in a magnetic field when electric current flows through them. They are fundamental components used in a wide range of electronic circuits for filtering, energy storage, and impedance matching.

Applications:

• DC-DC converters
• Power supplies
• EMI/RFI filtering
• RF circuits
• Signal processing circuits
• LED lighting

Features:

• Fixed Inductance Value: Offers a specific, non-adjustable inductance value.
• Compact Size: Designed for space-constrained applications.
• High Current Handling Capability: Suitable for applications requiring high current.
• Low DC Resistance (DCR): Minimizes power loss and improves efficiency.
• Shielded Construction (Potentially): Some variants may feature shielded construction to reduce electromagnetic interference (EMI).

Benefits:

• Effective Filtering: Filters out unwanted noise and ripple in power supplies and other circuits.
• Energy Storage: Stores energy in DC-DC converters to efficiently regulate voltage and current.
• Impedance Matching: Matches impedance in RF circuits for optimal signal transfer.
• Reliable Performance: Provides stable and reliable performance in various operating conditions.

Additional Details:

The 82473C's specific inductance value, tolerance, current rating, and DC resistance are critical parameters that need to be considered during circuit design. Murata Power Solutions provides detailed datasheets specifying these parameters, as well as dimensions, material composition, and operating temperature range. Shielded inductors minimize EMI, making them suitable for sensitive applications. Selection should be based on the specific requirements of the application and a review of the datasheet specifications. Additional parameters to consider may include the self-resonant frequency (SRF) and the Q factor, which can impact performance in high-frequency applications.
