Automotive-grade semi-shielded power inductor serves harsh environments
AEC-Q200-compliant for high reliability in certain harsh environments, the Model SRN6045HA power inductors feature a wide operating temperature range up to 125 degrees C. Available from Bourns, the inductors have semi-shielded construction to combine the features of non-shielded and shielded inductors, and offer lower magnetic field radiation than non-shielded inductors.
The inductors are a more cost-efficient alternative to fully shielded ferrite-based inductors, says Bourns, yet allow high temperature operation compared to standard semi-shielded inductors.
The inductor series is AEC-Q200-compliant with an operating temperature range of -55 to +125 degrees C, suitable for power management and EMI filtering in automotive, consumer, industrial and telecomms equipment.
The magnetic silicon-based coating used in the new inductors enables high working temperatures and extends the operating temperature range by 20 per cent on the high end compared to standard Bourns semi-shielded power inductors. The high-temperature magnetic silicon-based coating is applied to the perimeter of the inductor winding to provide effective magnetic shielding.
Characterised by high operating temperature, compact size and low losses, the Model SRN6045HA series also features high current capacity with saturation current Isat ranging from 1.2 to 18A and heating current Irms of 0.72 to 7.0A.
The automotive grade SRN6045HA series is available now with inductance values of 0.55 to 100 µH and is RoHS-compliant and halogen-free.
Bourns manufactures and supplies position and speed sensors, circuit protection solutions, magnetic components, microelectronic modules, panel controls and resistive products. Headquartered in Riverside, California, USA, Bourns serves a broad range of markets, including automotive, industrial, consumer, communications, medical (low/medium risk), and audio markets.
