Johanson Dielectrics manufactures high-reliability ceramic capacitors and EMI filtering components for power electronics, aerospace, defense, medical, semiconductor equipment and demanding industrial applications. Its portfolio includes surface-mount MLCCs, high-voltage MLCCs, 200°C high-temperature capacitors, automotive-grade mid-voltage high-capacitance devices, AC safety capacitors, X2Y® EMI filters and decoupling capacitors, PolyTerm® ceramic capacitors, leaded high-voltage and high-temperature capacitors, switch-mode stacked capacitors, planar-array capacitors and CapStrate® ceramic capacitor substrates. Product technologies address high voltage, high capacitance, high temperature, mechanical stress and EMI suppression. Johanson also provides prototyping kits, SPICE models, S-parameters and PCB layout resources. Current development includes high-capacitance leaded ceramic solutions for aerospace, defense, energy, medical and EV systems, together with qualified high-reliability capacitor offerings. These products are relevant where standard commercial MLCCs cannot meet voltage, temperature, reliability or filtering requirements. For RF design, the practical selection process also has to consider operating bands, antenna efficiency or RF gain, impedance matching, coexistence with adjacent radios, cable and connector losses, enclosure materials and the final installation environment. The manufacturer’s development resources are therefore useful during schematic definition, PCB layout, antenna placement, prototype tuning and compliance preparation. Engineers can use the available product families to compare integration level, antenna format, radio interface and environmental requirements while keeping the wireless architecture aligned with the mechanical design. The official manufacturer website provides product-level technical information that can be used to compare available families and identify the most suitable technology for the intended electronic design. For Israeli engineering teams, Boran Technologies can support product identification and local commercial coordination for this manufacturer.
