In the 1940s radio was an important means of communication. Super heterodyne radio used Murata’s tubular 500pf ceramic capacitors with titanium oxide as dielectric material for temperature compensation.
Various kinds of Capacitors for Electronics, Electric Apparatuses and Power Utilities. Positive thermistors, Switching power supplies. Capacitor applied system and equipment. Double-layer Capacitors too.
“Since its founding in 1950, Nichicon has constantly been involved in the development, production, and sales of capacitors, circuit products, and other kinds of electronic components that are essential for many types of electronics.”
The product is one of the smallest in the industry and offers high sensitivity and high reliability. Nippon Liniax develops, produces, and markets measuring systems in a range of fields with a focus on strain-gauge-type pressure sensors and transducers. The product uses Nichicon’s proprietary thin-film processing technology.
“ROV metal oxide varistors help protect power systems from damage caused by transient overvoltage faults such as lightning, power contact, and power induction. Suitable for a broad range of applications, ROV devices help protect sensitive electronic equipment from potential power surge damage by clamping high-energy, short-duration impluses.”
“An ROV device is a varistor fabricated using a Zinc Oxide (ZnO) powder, sintered with other metal oxide ceramics. The resulting structure is a polycrystalline ceramic that consists of distributed ZnO grains, separated by other metal oxide ceramics.”
“A varistor is a variable resistor-a voltage dependent, non-linear device whose resistance decreases as the voltage applied across the device increases. ”
ROVs can also be used to help protect electrical equipment from damage caused by large voltage or power transients on the AC Mains inputs. In a coordinated circuit protection scheme the ROV can be paired with a PolySwitch overcurrent protection device to help improve equipment reliability and fulfill IEC-61000 test requirements.
CKE is a line of high voltage and high power silicon rectifiers, MOVs, selenium suppressors, silicon carbide varistors, and assemblies. These products are appropriate for a wide range of applications, and find a special fit in the power generation, resistance welding and RF power systems markets.
It consists of a 34mm square format varistor element ( MOV) with an integral thermally activated element designed to open in the event of overheating due to abnormal over-voltage, limited current conditions as outlined in UL1449.
