Murata：Commercialized polymer aluminum electrolytic capacitors that have achieved low ESR 4.5 mΩ with a thin design and high capacitance

　　Key features　　Achieved low ESR 4.5 mΩ with a thin design and high capacitance　　A low ESR product with high output noise level reduction effects　　Contributes to stable power supply for CPU, GPU, and FPGA of data centers and accelerators that require high currents　　Key applications: Server, accelerator, laptop PC　　Request a free sample on the “my Murata” registered members-only portal website　　Murata Manufacturing Co., Ltd. (hereinafter “Murata”) has developed the “ECASD40E477M4R5KA0” (hereinafter “this product”) polymer aluminum electrolytic smoothing capacitor that achieves low ESR (4.5 mΩ) while maintaining a thin design (2.0 mm Max) and large capacitance (470 μF) in a D case (7.3 x 4.3 mm), equivalent to conventional products*1. Mass production has already begun, and samples can also be provided.　　*1ECASD40E477M006KA0 (470uF/2.5V/6mΩ)　　In recent years, IT devices such as servers and accelerators used in data centers are being created to support larger currents. Since IC voltage fluctuation and heat generation are major issues that must be tackled to achieve stable device operation, it is necessary to both increase the capacitance of the capacitors used to suppress voltage fluctuations and to mount large, high-performance heat sinks (cooling units) on the ICs. Murata has proposed component costs reduction through problem solving using conventional low-profile and high-capacitance products as well as by reducing the number of components used.　　However, there is a growing demand for lower ESR products as a response to noise amplification due to the application of larger currents. Murata has now developed this product with a ESR value improved by 25% while maintaining the height and high-capacitance of conventional products. With this product, Murata contributes to providing stable device power supply while suppressing mounting areas and costs of electronic components.　　Specifications

Ameya360:Vishay Intertechnology Automotive Grade vPolyTan™ Polymer Tantalum Chip Capacitors Combine Low ESR With High Volumetric Efficiency

　　Vishay Intertechnology, Inc. introduced a new Automotive Grade series of vPolyTan surface-mount polymer tantalum molded chip capacitors. Designed to deliver improved performance in high temperature, high humidity operating conditions.       The AEC-Q200 qualified Vishay Polytech T51 series offers lower ESR, lower voltage derating, and a benign failure mode, while maintaining higher volumetric efficiency than traditional tantalum capacitors. In addition, these technological advantages set this technology above multilayer ceramic chip capacitors (MLCC) and aluminum capacitors in a comparable capacitance range.　　Offered in the compact D (EIA 7343-31) and V (EIA 7343-20) case sizes, the devices released today offer a wide capacitance range from 6.8 ?F to 330 ?F over voltage ratings from 2.5 V to 35 V and a capacitance tolerance of ± 20 %. Featuring a highly conductive polymer cathode system, the capacitors provide ultra low ESR from 120 mW down to 40 mΩ at +25 °C.　　Featuring a robust design for harsh environments, T51 series devices offer high temperature operation to +125 °C — with voltage derating above +105 °C — and a high temperature load time to 2000 hours. Combined with ripple current to 2.37 A, the capacitors are ideal for decoupling, smoothing, and filtering in switch mode and point of load (POL) power supplies for automotive ADAS, infotainment, and other in-vehicle electronic systems.
