Low-noise MEMs microphones from TDK target IoT apps
TDK Corporation announces an expansion of its ultra-low noise MEMS microphone family with the ICS-40740, delivering 70 dB (A) SNR with 133 dB sound pressure level Acoustic Overload Point. The low self-noise coupled with wide dynamic range makes the ICS-40740 ideal for voice controlled IoT applications, especially those with integrated loudspeakers, as well as wearable […]
Designing overvoltage protection for fire detection equipment
Author: Sonja Brown, EPCOS, a TDK Group Company The analyst firm Gartner predicts there will be nearly 25 billion IoT-enabled devices by 2020 – many of which will take the form of home automation, safety, security, appliance and entertainment equipment. A recent article on Smart Home technology cited a Coldwell Banker Real Estate survey that […]
The basics of thermistors in thermal management
Thermistors can reliably switch in thermal protection to keep power electronics cool. SONJA BROWN | EPCOS, A TDK GROUP CO. ALL SEMICONDUCTORS generate thermal losses, of course. Thermal losses in power semiconductors can range from a few watts to multiple kilowatts. In heatsinks, the conductive capability is typically measured in °K/W. The smaller the conductive […]
EMI suppression capacitors rated for 350 V AC
TDK Corporation presents a new series of robust EPCOS MKP X2 capacitors for EMI suppression. Compared with conventional X2 capacitors designed for rated voltages of 305 V AC, these new components offer a higher rated voltage of 350 V AC. This makes them suitable for EMI suppression in input filters – specifically for applications on […]
Advances in dc-link power capacitor technology
Compact and efficient dc-links have become practical thanks partly to ceramic capacitor designs that excel at thermal stability and feature low parasitic inductance. Matt Reynolds, EPCOS, a TDK…
Power inductors provide wide temperature range for automotive apps
TDK Corporation has further expanded its CLF-NI-D series of rugged power inductors with new types in three additional sizes: CLF5030NI-D with dimensions of 5.0 mm x 5.3 mm…
