The Eaton Bussmann DRA127-150-R is a fixed inductor. Fixed inductors are passive electronic components that store energy in a magnetic field when electric current flows through them. They are commonly used in circuits to filter, block, or bypass signals, and to provide energy storage.

Applications

• Power Supplies: Used for filtering and energy storage in switching power supplies.
• Radio Frequency (RF) Circuits: Employed in impedance matching networks, filters, and resonant circuits.
• DC-DC Converters: Vital components in boost, buck, and other DC-DC converter topologies.
• EMI Filtering: Used to suppress electromagnetic interference (EMI) in electronic devices.
• Signal Filtering: Smoothing and conditioning analog and digital signals.

Features

• Fixed Inductance Value: Offers a specific inductance (15uH in this case) that remains constant under normal operating conditions.
• Shielded Construction: Minimizes electromagnetic interference (EMI) radiated from the inductor.
• High Current Handling: Designed to handle relatively high current levels without saturation.
• Low DC Resistance (DCR): Minimizes power loss due to resistance in the inductor's winding.
• Surface Mount Technology (SMT): Facilitates automated assembly onto printed circuit boards (PCBs).
• RoHS Compliant: Complies with the Restriction of Hazardous Substances Directive, ensuring environmental safety.

Benefits

• Effective Filtering: Removes unwanted noise and ripple from power and signal lines.
• Stable Performance: Provides consistent inductance for reliable circuit operation.
• Reduced EMI: Shielded construction minimizes interference with other electronic components.
• Efficient Power Transfer: Low DCR minimizes power loss and improves overall circuit efficiency.
• Easy Assembly: SMT design simplifies the manufacturing process.

Additional Details

The DRA127-150-R has an inductance of 15µH. The "DRA127" likely refers to the series or package size of the inductor, with the "150" indicating the inductance value (15µH). The "-R" typically signifies RoHS compliance. Key specifications to consider include the inductance tolerance, saturation current, rated current, and DC resistance. These details can be found in the Eaton Bussmann datasheet for the DRA127-150-R. The physical dimensions, temperature rating, and self-resonant frequency (SRF) are also important for proper application and must be obtained from the official datasheet.
