Panasonic Corporation announced today that its Industrial Solutions Company has commercialized the new ZKU series of large-capacitance conductive polymer hybrid aluminum electrolytic capacitors for use in automotive ECUs (electronic control units), etc. and will launch mass production in August 2019. With increased capacitance, the largest product of this series with ϕ10 x 10.2 mm and […]
Three-phase 600-V gate driver with smart shutdown defeats negative voltage spikes
The STMicroelectronics STDRIVE601 3-phase gate driver for 600V N-channel power MOSFETs and IGBTs provides state-of-the-art ruggedness against negative voltage spikes down to -100V and responds to logic inputs in a class-leading 85ns. Featuring smart-shutdown circuitry for fast-acting protection, the STDRIVE601 turns off the gate-driver outputs immediately after detecting overload or short-circuit, for a period determined using […]
Tiny shielded power inductors are AEC-Q200 Grade 1 qualified
Coilcraft’s new XAL7050 Series of high-temperature power inductors is available with inductance values from 22 to 47 µH and current ratings as high as 5.5 Amps, with low DCR for greater efficiency. For lower inductance values, Coilcraft offers a lower-profile companion, the XAL7030, with an identical footprint and inductance range of 0.16 to 10 µH. The XAL7050 […]
Molded power inductors feature wide inductance range up to 8.2 µH
Coilcraft’s XGL4020 Series of high-performance, molded power inductors feature the industry’s lowest DC losses and extremely low AC losses for a wide range of DC-DC converters (from hundreds kHz up to 5+ MHz). Additional performance improvements include a wider range of inductance values and improved Irms current ratings. The XGL4020 is available in twelve inductance […]
EMI chokes offer greater than 40 dB common mode attenuation
Coilcraft’s new Cx Family of surface-mount common mode chokes includes 16 sizes/configurations for a broad range of power line circuits. They suppress high-frequency common mode noise up to 100 MHz and offer greater than 40 dB common mode attenuation, making them ideal for use in consumer electronics and industrial applications. All Cx Family EMI chokes feature […]

Bridge rectifiers handle 150-A surge current in SMD package
Taiwan Semiconductor Co., Ltd. (TSC)has announced the introduction of SMD TBS series bridge rectifiers (TBS406, TBS408, TBS410, TBS606, TBS608, TBS610) designed to optimize higher power application and prevents arcing problems through increased creepage distance with a wider pin distance (3.6 mm) between L to N. Designers benefit from a compact and thin profile package design with a profile height lower […]
Tiny current-sensing amps target overcurrent detection apps
Texas Instruments introduced the industry’s smallest current-sense amplifier in a leaded package and the smallest, most accurate comparators with an internal 1.2-V or 0.2-V reference. Offered in industry-leading package options, the INA185 current-sense amplifier, and open-drain TLV4021 and push-pull TLV4041 comparators enable engineers to design smaller, simpler and more integrated systems while maintaining high performance. […]
Bi-directional current sense amp targets full-scale direct motor-winding current measurements
Designers can now improve motor efficiency and reduce vibration using the MAX40056 bi-directional current sense amplifier with patented pulse-width modulation (PWM) rejection from Maxim Integrated Products, Inc. Creating a motor control system requires precise current sensing and measurement of motor winding currents. A commonly used approach is to infer winding currents by performing ground or supply […]
Tantalum nitride precision chips offer robust humidity withstanding
The RTAN Series from Stackpole withstands biased humidity testing at 85 degree C, 85% relative humidity, 10% rated power with very little resistance shift. In addition, the RTAN anti-sulfur materials and design is such that it will pass the rigorous ANSI / EIA-977 (method A) standard sulfur test, with minimal resistance shift. This performance is […]
