Johanson - AC Power Ceramic Capacitors
AC power ceramic capacitors by Johanson Dielectrics are specifically engineered to handle high voltage and high capacitance applications. These capacitors are available in various configurations, including the 1808 and 1812 sizes, and come with different voltage ratings, such as 1000V. Designed with Ni/Sn (RoHS compliant) terminations, these capacitors are typically used in environments where reliable performance and compliance with current environmental standards are crucial. The capacitors are tested to ensure they can handle significant temperature changes, boasting a capacity to operate effectively from 25°C to 75°C by maintaining a ripple current with a 50 ohm load. The AC power capacitors also exhibit strong dissipation factor versus AC volts characteristics and stable capacitance versus AC volts under X7R dielectric temp characteristics, making them ideal for a range of industrial, military, aerospace, and semiconductor processing equipment applications. Detailed specifications and ordering information can be referenced through their global part number breakdown, facilitating easy selection and procurement.
Johanson - Multilayer Ceramic Capacitor with EMI Filtering
This Multilayer Ceramic device integrates two balanced shunt capacitors featuring mutual inductance cancellation and shielding. Its monolithic broadband filter provides effective rejections for single-ended and differential configurations. Suitable for both EMI filtering and noise attenuation, it serves as an efficient EMC solution for common mode and differential noise problems. Offering superior performance over common mode chokes, this compact and versatile component operates within an ultra-low ESL environment, enhancing filtering effects. It is particularly useful in automotive applications, validated under AEC-Q200 standards, effectively replacing multiple discrete components. The EMI® capacitor contains two tightly matched, low inductance Y capacitors, ensuring effective high-frequency common-mode noise filtering. Designed for applications in power bypass, GSM RFI attenuation, USB and RJ45 signal lines, and various high-speed applications, it provides reduced component count and improved performance. Additionally, it features lower inductance and improved noise suppression. Johanson offers extensive application engineering support for schematic design and PCB layout, aiming to simplify the adoption of this high-performance EMI solution.
