SRR6028-221Y Description

Short technical summary and product information.

The Bourns SRR6028-221Y is a fixed shielded power inductor designed for high-density power management circuits. It offers a nominal inductance of 220 µH measured at 100 kHz with a wide tolerance of ±30%, typical for core-based inductors where saturation characteristics are prioritized over precision.

 

Electrically, the part features a maximum DC resistance of 820 mΩ, providing a balance between efficiency and size. The current handling is specified with two ratings: 360 mA RMS (Irms) for continuous operation based on temperature rise, and 450 mA saturation current (Isat) at which a typical inductance drop occurs. The self-resonant frequency is typically 820 MHz, and the inductor achieves a Q factor of 15 at 796 kHz.

 

Mechanically, the component is surface-mount with a maximum height of 3.00 mm. It operates over a temperature range of -40°C to 125°C, including self-heating, making it suitable for automotive and industrial environments. The shielded construction helps reduce electromagnetic interference.
