Bourns SRN8040HA Semi-Shielded Power Inductors

Bourns SRN8040HA Semi-Shielded Power Inductors are designed with a magnetic-silica coating to the perimeter of the inductor winding, offering effective shielding. These automotive-grade devices release lower magnetic field radiation than non-shielded inductors and are a cost-efficient alternative to fully shielded ferrite-based inductors. The SRN8040HA series is AEC-Q200 compliant and operates in a wide temperature range of -40°C to +150°C. Bourns SRN8040HA Semi-Shielded Power Inductors feature a 0.5µH to 100µH inductance range and 1.3A to 15A saturation current in a 7.9mm x 8.15mm x 4.2mm package. The series is ideal for DC-DC converters and power supplies in automotive, industrial, consumer, and telecom electronics applications that may require higher inductor reliability.
