Overview
The MURATA 22R473C is a fixed, unshielded wirewound inductor designed to store energy in magnetic fields, crucial for filtering and energy transfer in power electronics. Its specified inductance of 47 µH and a substantial current rating of 770 mA make it suitable for moderate power applications. A critical design consideration is its DCR of 220 mΩ, which, while acceptable for many uses, can lead to significant power dissipation and voltage drop in high-current, continuous-conduction mode (CCM) boost converter designs, necessitating careful thermal management or parallel configurations to mitigate efficiency losses.
Key Features
- Inductance: 47 µH
- Tolerance: ±10%
- Current Rating: 770 mA
- DC Resistance (DCR): 220 mΩ Max
- Q Factor: 50 @ 500 kHz
- Dimensions: 6.50mm Diameter, 10.50mm Height
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Switch-mode power supply (SMPS) output filtering
- Energy storage in buck converter stages
- RF impedance matching networks
- Choke coils in audio amplifier circuits
