Modeling Software Includes New Capacitor Series for Power Electronics in Harsh Environments

AVX Corporation, a manufacturer of passive components and interconnect solutions, has updated its SpiCalci 8.0 SPICE modeling software with two new high temperature multilayer ceramic capacitor series for power electronics employed in harsh environments.

Now featuring the SMX-style stacked, switch mode power supply (SMPS) MLCCs and SXP-style encapsulated, radial-leaded MLCCs— both of which are rated for up to 200°C and exhibit low ESR, ESL, and DC leakage in addition to excellent high frequency performance—SpiCalci 8.0 helps design engineers validate circuits before they are built by allowing them to simulate frequency performance plots and other data for specific AVX components.

Available in two dielectrics (C0G and X7R/X9U) with rugged mechanical shock and vibration capabilities and a wide frequency response in high pulse, high current, and high temperature applications, the new SXP-style and SMX-style MLCCs are ideal for down-hole oil exploration, space, aerospace, and hybrid automotive applications. Both series are suited for DC filters in high power, high frequency motor drives and high pulsed-current circuitry. Standard SMX MLCCs are rated for 25-500V and 1nF to 340µF, while standard SXP MLCCs are rated for 50-1,000V and 100pF to 10µF. Both series are available with custom values ratings, leads, and packaging upon request.
