Bourns, one of the world’s leading manufacturer of electronic components, has an extensive range of SMD Power Inductor products which have been designed to suit a wide range of Industrial and Consumer applications. The Bourns range of SMD Power Inductors are available in 4 formats to suit a broad range of application requirements.
SMD Non-shielded
The Bourns® non-shielded power inductor series include the SDE and SDR models. These models deliver very high inductance ranging from 0.68μH to 10,000μH and feature high-rated current with Irms up to 16 A and Isat up to 35 A. The families are available in sizes from 3.0 dia x 2.5mm height up to 22 dia x 7mm height for higher power requirements. The inductors operate over the temperature ranges -25°C to +105°C or -40°C to +125°C depending on the model selected.
SMD Semi-shielded
The Bourns® semi-shielded power inductor SRN series combines the best features of non-shielded and shielded inductors, making them ideal for use in power management for consumer and industrial applications. The SRN semi-shielded power inductor family has an inductance range from 0.24μH to 470μH with Irms rated up to 10 A and Isat up to 12 A. The family is available in sizes from the compact 2.0 x 1.6 x 1.0mm up to 10 x 9.8 x 6mm for higher power requirements. The inductors operate over the temperature ranges -25°C to +120°C, -40°C to +125°C or -55°C to +125°C depending on the model selected.
SMD Shielded
The Bourns® shielded power inductor series includes models SRE, SRR and SRU. The shielded power inductor family delivers very high inductances ranging from 0.47μH to 15,000μH and features high-rated current with Irms up to 20 A and Isat up to 22 A. The family is available in sizes from 2.8 dia x 2.8mm height up to 18.3 dia x 6.8mm height for higher power requirements. The inductors operate over the temperature ranges -25°C to +105°C, -40°C to +125°C or -55°C to +125°C depending on the model selected.
SMD High Current, Shielded
The Bourns® high current shielded power inductor SRP series have an inductance range from 0.1μH to 100μH and feature very high-rated current with Irms up to 55 A and Isat up to 118 A. The family is available in sizes from the compact 2.5 x 2.0 x 1.2 mm up to 17.3 x 16.9 x 6.7 mm. The inductors operate over the temperature ranges -40°C to +125°C, -55°C to +125°C, -40°C to +150°C or -55°C to +150°C depending on the model selected.
