Leading passive component suppliers Vishay, Bourns, and Coilcraft have recently launched multiple new inductors and transformers targeting automotive electronics, industrial power, BMS, and RF communications.
Vishay introduced four AEC‑Q200‑qualified common‑mode chokes: ICM5050‑A, ICM6050‑A, IFLN‑1210BE‑A, and IFLN‑1812CZ‑A. The ICM series uses wound ferrite construction with current ratings up to 11A (ICM5050) and 14A (ICM6050). The IFLN series (1210/1812 packages) offers typical common‑mode impedance up to 11kΩ at 100MHz. DCR ranges from 0.4mΩ to 12mΩ, with operating temperatures up to +150°C. Applications include DC‑DC converters, automotive Ethernet, lighting, and battery‑powered gear – with IFLN series suited for CAN/LAN EMI suppression.
Vishay also expanded its transformer portfolio with the IFBT series of customizable surface‑mount flyback transformers (17 models). Input voltage 26‑72V, 250kHz switching, isolation voltage 1500VRMS (60s) between primary/bias/secondary windings. Output range 1.8‑24V at 0.5‑9.0A, inductance 35‑75µH, operating temperature ‑40°C to +125°C. Targeting 6W‑30W PoE and isolated DC‑DC converters up to 30W – for automotive LED lighting, energy management, industrial automation, building control, white goods, telecom, and medical instruments.
Bourns released the SM91534ALA automotive‑grade BMS signal transformer, a single‑channel device with integrated common‑mode choke. Rated 1500VDC working voltage, 6400VDC hipot test, withstands 12kV impulse (1.2/50µs). Inductance 150‑450µH, creepage/clearance >16.6mm, supports up to 5,000m altitude. AEC‑Q200 and UL certified, operating temperature ‑40°C to +125°C, package 31.5×12.5×9.5mm. Designed for EV/HEV battery BMS and energy storage packs – for isolation communication and sensing signal links in high‑voltage battery systems.
Coilcraft updated its 0201DS series miniature ceramic chip inductors with halogen‑free versions and 20 new values, expanding the family to 52 inductance options covering 0.5‑14nH. The 0201 wire‑wound RF inductors offer Q factor up to 64 at 1.7GHz and self‑resonant frequency exceeding 24GHz. Operating temperature up to +140°C, halogen‑free, RoHS compliant. Suitable for high‑frequency RF circuits and mobile terminals, handling narrow‑band isolation and signal filtering.
ICgoodFind Takeaway:
Automotive BMS, high‑voltage isolation, and RF miniaturization are driving the latest passive component rollouts. Vishay, Bourns, and Coilcraft are all filling specific gaps – from 14A common‑mode chokes to 24GHz RF inductors – giving designers more precise options.
