Knowles Corporation introduces its latest series of SiSonic MEMS microphones: Titan (Digital), Falcon (Differential Analog), and Robin (Single Ended Analog). The new trio of microphones provides advanced performance capabilities for space-constrained Ear and wearable applications like True Wireless Stereo (TWS) earbuds, smart watches, Augmented Reality (AR) glasses, and Virtual Reality (VR) headsets. Each of the […]
Applications
Precision thin-film resistors offer ±0.01% tolerances, ±2ppm TCRs
With the proliferation of electronics in nearly every market sector, there is an increasing need for precision resistors. For markets such as medical instrumentation and control, industrial and automotive controls, communications, and test & measurement, these precision resistors must maintain electrical and environmental stability long term. Stackpole’s RNCF series of precision thin film resistors meet these […]
What causes signal attenuation in a PCB and how can it be controlled?
Except for the most basic designs, system clock rates are inexorably creeping upward across a wide range of applications, from 5G telephony to automotive advanced driver assistance systems (ADAS), medical, industrial, and mil/aero systems. As frequencies rise into the GHz range, the need for impedance control to minimize signal attenuation and protect signal integrity gets […]
Automotive-grade chip resistors excel at handling pulses
High-reliability chip resistors can be more difficult to find and even more so when there are pulse handling requirements. Typically, the manufacturing process for thick film chip resistors allows for variation in the calibration trim, leading to variation in pulse handling performance. Stackpole’s recently released RPCA series addresses all these needs. The RPCA has limited to […]
6MHz rail-to-rail op amps boost performance in industrial and automotive apps
STMicroelectronics is simplifying designers’ search for high-performing operational amplifiers (op amps) by introducing three new 6MHz rail-to-rail devices with strong all-around parameters including a wide operating voltage range and low noise. The TSB511, TSB512, and TSB514 are single, dual, and quad op amps, respectively. They can operate from a single supply in the range from 2.7V to […]
Where are cloud connected relays used?
Relays are humble devices, but they are not immune to being impacted by the Internet of Things. Electromechanical relays, solid-state relays, and MEMs relays are among the numerous devices in the IoT that can connect to the cloud. Some relays include Wi-Fi controllers or Bluetooth, some use power over Ethernet (PoE), and others use voice […]
LEDs optimized for low-current, low-light apps
ROHM Semiconductor announced the availability of the CSL1901 series of 0603-size (0.6-inch × 0.3 inches) / 1608-size (1.6 mm × 0.8 mm) LEDs, optimized for low-light applications for use in indicators and numeric displays in factory automation equipment (i.e., PLCs) and communication control equipment such as modems and routers. In recent years, technological advancements in LED […]
Confused about RF-band letter designations? That’s not surprising!
Frequency bands within the electromagnetic spectrum have multiple, sometimes confusing, overlapping designations. Electronics engineers must deal with the electromagnetic spectrum as a routine part of their wired and wireless projects. This spectrum of interest ranges from relatively low frequencies in the kilohertz (kHz) range (or perhaps lower) into the tens and even hundreds of gigahertz […]
