Smyrna, Ga. Designed for high-speed differential transmissions and noise suppression for compact mobile equipment such as cell phones and digital cameras, Murata Electronics North America said it has developed the industry's smallest common mode choke coil. Dubbed the DLP0NS series, this tiny mode choke coil is thinner and lighter than its predecessors, measuring 0.85 x 0.65 x 0.45 mm.
As consumer products shrink and become more multi-featured, noise from differential transmission methods (i.e. USB2.0, IEEE 1394, DVI and HDMI for PCs and their respective peripherals) grows increasingly problematic. The DLP0NS series is designed to remove the unwanted noise without impacting high-speed signal waveforms. The coils achieve this because of increased characteristic impedance (67 ohm, 90 ohm and 120 ohm) and high coupling (k≥0.98), said the company.
The RoHS-compliant device is available for the sample price of 30 cents. Delivery is approximately eight to ten weeks.
