SRN5020-1R0Y is a semi-shielded power inductor from Bourns designed for high-current DC/DC converter applications in compact electronic devices. It features a 1.0 µH inductance with 30% tolerance, a maximum DC resistance of 0.025 O, and a rated RMS current of 3.6 A with a saturation current of 4.0 A. The inductor exhibits a self-resonant frequency of 85 MHz at a test frequency of 7.96 MHz, with a quality factor (Q) of 13, and operates reliably over a temperature range of -40°C to +125°C. Its compact semi-shielded construction with a maximum component height of 2 mm, combined with RoHS compliance and halogen-free materials, makes it ideal for space-constrained applications such as notebook computers, digital video cameras, and LCD display systems.
