SRN Semi-Shielded Power Inductors

Bourns SRN Semi-Shielded Power Inductors are available in several package sizes that are designed using semi-magnetic shielding technology. These inductors offer semi-shielded construction with a rated current from 200mA to 12A and can be used for DC/DC converters, notebook computers, digital video, cameras, HDDs, cell phones, televisions, LCD displays, and much more. The SRN series provides effective magnetic shielding while emitting lower radiation compared to non-shielded inductors. Bourns SRN Semi-Shielded Power Inductors also offer cost savings compared to similar-sized conventional ferrite shield inductors. The Semi-Shielded Power Inductor SRN Design Kit includes the SRN3015, SRN6045, and SRN8040 series products with a total of 32 part numbers (five per each part). The kit offers inductance ranges from 0.47µH to 100µH and rated RMS current from 0.29A to 7.8A.
