Automotive-grade inductor duo withstands harsh vibration
Two power inductors from Bourns have a wide side terminal frame to withstand 15G typical or 30G peak vibrations. According to the company, the Model SRP1038WA and SRP1265WA automotive grade high current shielded power inductors offer enhanced mechanical strength for harsh vibration application environments.
The Model SRP1038WA and SRP1265WA shielded power inductor vibration performance exceeds the 5G demanded by the AEC-Q200 standard. Vibration testing was conducted according to MIL-STD-202 Method 204. The two inductor series feature a compact package, high saturation current, low DC resistance, low buzz noise and temperature stability over a wide temperature range of –55 to +165 degrees C. These features make these automotive-grade, AEC-Q200-compliant power inductors for power management and EMI filtering in a range of consumer, vehicle, industrial and telecomms electronics applications.
The width of the side terminal frame is more than 50 percent compared to existing Bourns models without increasing the package size or required PCB area, said Bourns. Bourns has formulated a metal alloy powder core and bonding agent which it uses with a moulded construction manufacturing process where the magnetic shielded design allows for low radiation while the metal alloy powder core provides high saturation current. The high temperature-grade materials used enable a wide operating temperature range suitable for many types of harsh environment applications. The maximum operating temperature of +165 degrees C is 10 per cent higher than standard Bourns Model SRP-A power inductors. The new models provide more headroom to maintain the rated operating current even under challenging environmental conditions.
The Model SRP1038WA and SRP1265WA power inductors are available now and are RoHS compliant and halogen free.
Bourns is a manufacturer and supplier of position and speed sensors, circuit protection solutions, magnetic components, microelectronic modules, panel controls and resistive products. Headquartered in Riverside, California, USA, the company serves a broad range of markets, including automotive, industrial, consumer, communications, medical (low/medium risk) and audio market segments.
