Power-supply noise, Part 2: What is differential mode noise?
Part 1 looked at the basics of noise, especially concerning power supplies. There are two noise sources which are not as obvious to many engineers as noise that results from the switching action of the power supply: differential mode noise and common-mode noise. These two noise modes have different causes and thus different solutions Q: […]
Power-supply noise, Part 1
“Noise”—perhaps nothing worries design engineers as much as the implications of this single five-letter word. There are good reasons for this worry. Noise is often unpredictable; may come from internal and somewhat controllable sources, or external impossible-to-control sources; it can affect performance accuracy and consistency; it can cause products to not meet their target design […]
Nordic-based BLE module enables IoT solutions for consumer products, appliances, healthcare equipment
MBN52832 is a Bluetooth Low Energy/NFC module. It enables ultra-low power connectivity for data communication. The module integrates Nordic Bluetooth Low Energy IC, RF front end, and crystal into a very small form factor. The built-in ARM Cortex M4 core with 64KB RAM and 512KB flash provides a high performance engine and rich interfaces for […]
Common-mode line filters for SMPS replace discontinued units
The PMCU Series of common mode line filters is designed for switching power supply applications. Offered in both standard winding (for higher efficiency) and sectional winding (for improved high-frequency performance), the updated PMCU offerings have been expanded to include a direct cross for over three dozen PLA10ANxxx and PLA10ASxxx EMIFIL series components recently discontinued by […]
Loop-powered, 4-20 mA LED display process monitor housed in DMR20 package
Murata has introduced a new line of 4-20mA loop-powered process monitors from Murata Power Solutions. Featuring high-visibility LED displays, its operating power is derived directly from the current loop without requiring an external source. This new series is housed in the familiar round DMR20 polycarbonate package. The DMR20-4/20 series is the smallest 4-20mA process monitor […]
Convection-cooled 250-W ac-dc power supplies handle limited airflow applications
Murata announces its new wide input range, single output PQC series of industrial/medical power supplies from Murata Power Solutions. Rated at 250 watts of output power in an industry-standard open frame 3 x 5 inch, 1U footprint, this high-efficiency design can deliver full power with free-air natural convection cooling up to 50°C. The PQC series […]
SAW filters target Wi-Fi use with steep skirts, minimal insertion loss
Murata Manufacturing Co., Ltd. has released a new Incredibly High Performance (IHP) SAW filter (measuring just 1.1 x 0.9 mm) for Wi-Fi applications that delivers greater steepness, insertion reduction, and temperature characteristic stability compared to conventional models. Using the company’s new proprietary SAW technology to achieve these benefits, the SAFQ2G45MA0G0A series is ideal for ISM2.4GHz RF circuits in mobile devices, such as smartphones […]
