Johanson Dielectrics, Inc. has been a worldwide producer of high quality ceramic chip capacitors for over 30 years. Their success has enabled steady expansion of manufacturing facilities and focus on new product development ensuring the company's ability to respond to the ever changing needs of their customers. Johanson Dielectrics' corporate mission is to achieve profitable growth by totally satisfying customer's requirements for high quality, technologically advanced ceramic chip capacitors.
Johanson Dielectrics High-Voltage Surface Mount MLCCs offer voltage range from 250 - 6,000VDC and feature a special internal electrode design which reduces voltage concentrations by distributing voltage gradients throughout the entire capacitor. This unique design of the high-voltage SMT MLCCs from Johanson Dielectrics results in increased capacitance values in a given case size and voltage rating. These MLCCs, available in NPO and X7R dielectrics, have a capacitance range from 10pF to 0.47µF and are suitable for a wide variety of telecommunication, commercial, and industrial applications.
Johanson Dielectrics TANCERAM® Chip Capacitors offer several advantages over tantalum capacitors and can replace tantalums in many applications. The TANCERAM® Chip Capacitors from Johanson exhibit extremely low ESR which allows equivalent circuit performance to
be achieved using considerably lower capacitance values. In addition, TANCERAM capacitors have low DC leakage which reduces current drain and extends the battery life of portable products. TANCERAM
chip capacitors also deliver high DC voltage breakdown ratings for
improved reliability and eliminate the large voltage de-rating that
occurs commonly with tantalum capacitors.
Johanson Dielectrics X2Y® Filter Capacitors are designed with a unique, patented low-inductance construction that features two balanced capacitors that are immune to temperature, voltage and aging performance differences. One X2Y Filter Capacitor from Johanson performs EMI suppression or decoupling, replacing multiple capacitors and inductors, which saves board space and reduces assembly costs.
Johanson Dielectrics AC Safety Capacitors are ceramic chip capacitors designed for AC voltage surge and lightning protection in line-to-ground interface applications in computer networks, modem, facsimile and other equipment. The AC Safety Capacitors from Johanson are available in four different case sizes and NPO and X7R dielectric material. These capacitors are surface mountable and offer 250VAC voltage and capacitance range from 5pF to 4700pF.
Johanson Dielectrics Ceramic Capacitor Design Kits are multi-layer chip capacitor sample kits grouped by type, size, or voltage for prototype designs. These ceramic capacitor design kits from Johanson contain a selection of popular values and tolerances, and the chips contained in each kit are individually packaged in labeled plastic compartments for easy access. Kit selections include 500VDC, 1000VDC, 2000VDC, high capacitance, X2Y® EMI Filter, X2Y® DC Motor filter, and more.
