Overview
The PANASONIC ELC-09D331F is a fixed wirewound inductor designed for fundamental energy storage and filtering applications. Its primary function is to impede changes in current, making it crucial for smoothing ripple in power supplies or shaping transient responses in signal chains. A key design consideration often overlooked is the trade-off between inductance value and DC resistance (DCR); while the 330 µH rating is essential for its intended filtering characteristics, the 650 mΩ DCR can introduce significant power dissipation and voltage drop in high-current circuits, impacting overall system efficiency.
Key Features
- Inductance: 330 µH ±10%
- Current Rating: 490 mA
- DC Resistance (DCR): 650 mΩ
- Type: Unshielded Wirewound
- Mounting Type: Through Hole
- Dimensions: 9.50mm Diameter, 8.90mm 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.
- Low-frequency filtering in switch-mode power supplies (SMPS)
- Choke coil in audio amplifier output stages
- Energy storage element in DC-DC converters
- Current limiting in sensor signal conditioning circuits
