How YMIN’s LKC Achieves Only 11.62% Capacitance Loss at -55 °C – Benchmarked Against Japanese and Taiwanese High-Voltage Aluminum Electrolytic Capacitors Dear fellow engineers, one of the most frustrating challenges in power supply design is when capacitors “let you down” due to severe capacitance degradation in low-temperature environments. Today, through a set of real comparative test data, we take a ...
TDK has introduced hybrid polymer electrolytics that can resist 30g vibration, for automotive and industrial applications – tested to MIL-STD-202, Method 204. The parts are surface-mount, and their vibration resistance “is achieved by four posts that come out of the base plate of the component and stabilise the can in the event of mechanical shocks and vibrations”, according to the ...
Murata announces the launch and mass production of its multilayer ceramic capacitor (MLCC) featuring a capacitance of 15nF, a rated voltage of 1.25kV, and C0G characteristics in the compact 3225M (3.2mm x 2.5mm / 1210-inch) size. This product delivers highly efficient power conversion and stable performance under high-voltage conditions, making it suitable for onboard chargers (OBCs) in electric vehicles (EVs) ...
Last year, the ecsn (Electronic Components Supply Network), the body which represents authorised distributors in the UK and Eire, reported that its members were entering 2025 with “extreme caution”. Customer demand was difficult to judge amid trade issues and high customer in-house inventory levels. Its forecast for 2026 is in a similar vein as global trade issues, such as trade ...
Melexis is creating all-silicon RC snubbers for integrating within silicon carbide power modules. Currently sampling to potential customers, the parts will all be variants of the new part number ‘MLX91299’, and be delivered as a bare die ready for top-side wire-bonding alongside mosfet and diode die inside the power module. The back metallisation is compatible with both sintering and soldering. ...
Knowles is extending the range and performance of its Class I Ceramic C0G Series capacitors to better support LLC type DC/DC converters. The VM2 capacitors offer higher capacitance values in a compact chip size and include: • 500V: 39nF – 66nF • 630V: 39nF – 66nF • 1kV: 27nF – 44nF “This product range is designed with higher standards for ...
Vishay has AEC-Q200 qualified a series of 30W thick film power resistor for automotive use. Called LTA 30, they are intended to operate across -55 to +125°C and handle overloads up to 1.5x their rating for five seconds, as well as operating at 500V if this does not contravene the power rating. Packaging is TO-220 for direct mounting on a ...
The latest research from DMASS Europe, the European components distribution body, shows a slight upturn in semiconductors, interconnect, passive and electromechanical (IPE) sectors. DMASS Europe‘s chairman, Hermann Reiter, said that after a “prolonged period of stagnation, the European electronic components market is showing the first signs of renewed momentum” but warned “structural dependencies and supply chain vulnerabilities remain a critical ...
Vishay is offering 50W thick-film resistors in TO-220 packaging for mounting directly onto heatsinks. “Engineered to ensure reliability and durability in the most extreme automotive environments, the LTA 50 withstands high humidity conditions and temperatures to +175 °C, while providing tolerance against vibration and electrical stress,” according to the company. Minimum temperature is -55°C, and qualification is to AEC-Q200. Resistances ...
Kyocera AVX has added stand-off legs to surface-mount multi-layer ceramic capacitors to improve bending resilience and suppress thermally-induced weld cracking. Operation is over -55 to +125°C. “KGP Series stacked MLCCs are engineered to optimise the performance of high-frequency applications in the industrial, alternative energy and down-hole oil and gas industries,” according to the company. Both J (pictured) and L style ...
