Low-Distortion Noise Suppression Filter for Audio Lines
TDK Corporation has released their new MAF1608G noise suppression filter for audio lines. The miniature component (1.6 mm x 0.8 mm x 0.8 mm) features a high rated current of 1.6 A and a low DC resistance of 0.06 Ω. This makes the MAF1608G noise suppression filter optimally suited for use in speaker lines where high currents are required. These applications include earphones, … [Read more...]
CISPR 35 Up for Final Vote
The final draft international standard (FDIS) for CISPR 35 has just been circulated to national Committees, with a closing date for voting of July 8 2016. It is dual-voted in CENELEC as well, but it might pass in IEC but not in CENELEC, so the future of the EN clone, EN 55035, is still somewhat uncertain. CISPR 35 is a new standard for broadcast receivers, information … [Read more...]
