MEMS 32.768 kHz resonator billed as world’s smallest
Murata has a tiny 32.768 kHz MEMS resonator (the WMRAG series), which is expected to make a significant contribution to reducing the size and power consumption of IoT devices and wearable devices. Demand is growing for compact electronic components that consume less electrical power for use in digital devices for IoT and wearable applications where […]
Digital step attenuators come in 2-bit, 5-bit, 6-bit or 7-bit configurations
AT IMS, pSemi Corporation (formerly Peregrine Semiconductor), announced the expansion of its digital step attenuator (DSA) portfolio with a family of value, high-performance DSAs. The four digital step attenuators feature industry-leading attenuation accuracy at an entry-level price point. “pSemi has a long, successful history of digital step attenuator development,” says Jim Cable, CTO at pSemi. “Our team […]
Line filters are designed to replace discontinued Murata Components
Premier Magnetics announces the in-stock availability of its PMCU Series of common mode line filters designed for switching power supply applications. Offered in both standard winding (for higher efficiency) and sectional winding (for improved high-frequency performance), the PMCU line models provide a direct cross for over three dozen PLA10ANxxx and PLA10ASxxx EMIFIL series components recently […]
Power-supply noise, Part 2
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 […]
