How are accelerated life tests changing for high-voltage EV power electronics?
For many years, standards such as AEC-Q101 and the “test-to-pass” method were the only ways to enter automotive power electronics. But since the powertrain has become electric, these static qualification methods are no longer enough. Electric Vehicles (EVs) use high-voltage traction inverters that must handle changing thermal and electrical stresses not covered by standard industry […]
Low-distortion ferrite cuts audio-line noise without signal degradation
TDK Corporation has announced the MAF0603GWY series, noise suppression filters measuring 0.6 mm × 0.3 mm × 0.3 mm for smartphones, tablets and wearable devices, with mass production scheduled for April 2026. The series uses a proprietary low-distortion ferrite material to suppress high-frequency noise from audio lines while minimizing changes to audio characteristics, with impedance […]
Molded shielded inductors rated to 50 A in 5.6 × 5.2 mm footprint
Coilcraft has released the KTA5050, a molded shielded power inductor series in a 5.6 × 5.2 × 5.0 mm package, with inductance values from 65 nH to 600 nH and saturation current ratings up to approximately 50 A for the lowest inductance variants. The composite core is optimized for low AC losses at high switching frequencies, with […]
Why isn’t scaling to heavy-duty EVs as simple as adding more voltage or battery capacity?
Scaling battery-electric vehicle (BEV) architectures for heavy-duty applications involves nonlinear variables that differ significantly from those in passenger vehicle development. Standard industry practices, such as increasing energy capacity through additional modules or raising system voltage, encounter physical and thermodynamic limits when applied to high-mass platforms. This FAQ examines the technical reasons why pack-level scaling is […]
