The SRP5020C-3R3M is a shielded power inductor from Bourns Inc., designed for high-current applications requiring a compact and efficient solution. The '3R3M' denotes an inductance value of 3.3 μH with a ±20% tolerance.

Applications

• DC-DC converters
• Voltage Regulator Modules (VRM)
• Point-of-Load (POL) converters
• Power supplies for portable devices

Features

• Shielded construction
• Compact size: 5.0 mm x 5.0 mm x 2.0 mm
• Inductance: 3.3 μH
• Tolerance: ±20%
• High saturation current
• Low DC resistance

Benefits

• Minimizes electromagnetic interference (EMI) with its shielded design.
• Ensures efficient power conversion due to its low DC resistance.
• Suitable for applications with limited board space.
• Provides stable performance under high current conditions.

Additional Details

The SRP5020C-3R3M's shielded construction reduces electromagnetic radiation, making it well-suited for sensitive electronic devices. It is designed for surface mount assembly and is RoHS compliant. The composite construction allows for higher current handling than similarly sized wire-wound inductors.

Technical Specifications:

• Inductance: 3.3 μH ±20%
• DC Resistance (DCR): 0.014 Ohms (typical)
• Saturation Current (Isat): 5.5 A (current at which the inductance drops by 30%)
• RMS Current (Irms): 5.0 A (current that causes a 40 °C temperature rise from 25 °C ambient)
• Operating Temperature: -40 °C to +125 °C (including self-heating)
• Shielded: Yes
• Termination Finish: Matte Tin over Nickel
