SRN4018TA-3R3M Description

Short technical summary and product information.

The Bourns SRN4018TA-3R3M is a semi-shielded wirewound fixed inductor designed for surface-mount applications. It offers an inductance of 3.3 µH with a ±20% tolerance, measured at 100 kHz and 1 V. The component provides a typical self-resonant frequency of 60 MHz, making it suitable for power and signal line filtering in DC-DC converters and other switching circuits.

 

This inductor is rated for a typical RMS current of 2.3 A and a saturation current of 2 A. The typical DC resistance is 0.055 Ω at 25 °C. The device operates over a temperature range of -55 °C to +125 °C, including temperature rise, and has a storage temperature range of -55 °C to +125 °C. The temperature rise at rated Irms is 40 °C.

 

The semi-shielded construction helps reduce magnetic flux leakage, improving performance in dense PCB layouts. The component is housed in a compact SMD package suitable for automated assembly.
