Multilayer varistors withstand severe flexing, vibration, and temperature cycling
KYOCERA AVX has released the industry’s first automotive-qualified multilayer varistors (MLVs) equipped with the company’s patented FLEXITERM soft termination technology, which has been widely employed on a number of automotive-qualified multilayer ceramic capacitors (MLCCs) for more than 15 years. Designed to satisfy automotive industry demands for more robust component solutions, the new VCAS Series MLVs with FLEXITERM […]
Foil-on-ceramic sense resistors feature resistance values to 0.1 milliohm
Current sensing for a wide range of products and applications requires both low and high resistance values with high stability, reliability, and low TCR. For devices that need somewhat higher resistance values, high current handling, low TCR, and high stability, finding cost-effective solutions can be challenging. Film-type resistors will not have high current handling, and […]
BMS protection board target large-capacity lithium battery packs
In recent years, with higher requirements for the production and manufacturing of new energy vehicles and increasing demand for safer drive batteries, high-performance drive battery BMS has been valued highly and its market share has grown sharply. According to statistics, the market size of BMS in China reached 9.7 billion yuan in 2020, with a year-on-year growth of 6.6%, […]
Silicone gap filler offers enhanced options for power applications
Sarcon GR25B is an advanced silicone, gel-like thermal interface material delivers a thermal conductivity of 2.5 W/m•K and is a widely used choice for higher power electronics applications. GR25B is offered in double sticky surfaces, hardened surfaces for easier handling, with polyester mesh to prevent stretching or with both hardened surface and mesh for more […]
Selecting a gate driver for ASIL-certified systems
Several safety features now found in gate driver integrated circuits make it easier for automotive system designs to get ASIL certification. David Divins • Infineon Technologies The Automotive Safety Integrity Level (ASIL) is a risk classification system defined by the ISO 26262 standard for the functional safety of road vehicles. There are four ASIL safety […]
Where depletion-mode power MOSFETs excel
Depletion-mode MOSFETs have qualities that let them work well in several kinds of power-handling circuits. Aalok Bhatt, José Padilla, Raymon Zhou • Littelfuse, Inc. Most MOSFETs are enhancement-mode (EM) devices: When their gate-source voltage is zero, they don’t conduct. When the need is for a switch that is normally on when there is no power […]
Calculations reveal the value of efficiency
A few back-of-the-envelope estimates show why it pays to maximize power supply efficiency. Chris Harman • Puls l.p. Engineers are becoming more sensitive to efficiency when selecting a power supply. Energy flows through the supply, and something less than 100% of that energy can be used because of inefficiencies of power supply components. The difference […]
High-voltage 10-kV supplies include high-voltage flying lead
Dean Technology, Inc. announced the introduction of a new series of high voltage power supplies designed specifically for higher voltage applications needing a biasing module. The new UMR-A-10000 series, which is another extension of the existing UMR Collection of power supplies, offers output voltages up to 10kV, input voltages at 12 or 24V, and power […]
