Software Enables Viewing of Oxicap Capacitors

The latest version of AVX's Spitan III applications software enables designers to view all basic characteristics and parameters for tantalum and Oxicap (niobium oxide) capacitors. The company has also introduced an S-parameter Library in v1.1, which includes s2p files. Spitan III v1.1 enables the designer to choose a desired component by actual part number or by reference to capacitance, rated voltage, case size or series.

For selected capacitors, all basic parameters such as the frequency characteristics of capacitance, ESR, impedance, DF, and ripple current and voltage ratings are displayed. Furthermore, leakage current DCL versus time progress can be studied and an equivalent circuit diagram with values of all elements can be displayed. All graphs can be exported either as pictures or as data for further evaluation - for example in Excel. This latest version of Spitan III, v1.1, includes part numbers of various SMD chip capacitor series released during 2010.

For the first time, high-reliability and performance wet tantalum axial capacitors are presented in the software database. New features include maximal ESR curves versus frequency and temperature, maximal leakage current DCL curve versus time and S-parameter s2p files generator. AVX has also added an additional library, S-parameter s2p Library v1.1, with files for all tantalum and Oxicap (niobium oxide) capacitors. S-parameter files are useful for high-frequency application circuit simulation.

The standard s2p format library for Tantalum and Niobium Oxide capacitors is generated for all part numbers of the latest Spitan III v1.1 database. More than 6,400 files are included - where two files are linked to each part, one for series connection in two-port networks and the other for shunt connection. The updated calculus allows a pair of s2p files to be generated separately for each selected capacitor from Spitan III v1.1 simply by using a single dedicated button.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
