The ELL6SH3R3M is a fixed inductor manufactured by Panasonic. This inductor is designed for various electronic circuits, offering filtering, energy storage, and impedance matching capabilities. The '3R3' within the part number typically denotes an inductance value of 3.3 µH (microhenries). The 'M' likely refers to the tolerance of the component.

Applications

• DC-DC converters: Provides energy storage and filtering for efficient voltage conversion.
• RF circuits: Offers impedance matching and tuning in radio frequency applications.
• EMI filtering: Suppresses electromagnetic interference in electronic devices.
• Signal filtering: Removes unwanted noise or frequency components from signals.
• Power supply filtering: Smoothes voltage ripple and reduces noise in power supplies.

Features

• Inductance: 3.3 µH (microhenries - refer to the datasheet for specific tolerance).
• Tolerance: Commonly ±20% (check datasheet for exact value).
• Rated Current: Indicates the maximum current the inductor can handle without significant degradation.
• DC Resistance (DCR): The resistance of the inductor's coil, which influences efficiency.
• Self-Resonant Frequency (SRF): Frequency at which the inductor's impedance is at its peak; crucial for high-frequency applications.

Benefits

• Efficient Energy Storage: Stores energy effectively in DC-DC converters.
• Effective EMI Suppression: Reduces unwanted noise and interference.
• Precise Impedance Matching: Optimizes signal transfer in RF circuits.
• Improved Signal Quality: Filters out noise for cleaner signals.
• Compact Size: Allows for use in small electronic devices.
