AVX Expands TPM Range Of Tantalum Capacitors

AVX has expanded its TPM series of multi-anode mirror-design tantalum capacitors, offering improved robustness and featuring very low ESR. The D-sized TPM 47uF/25V part offers an ESR of 55mohm. In comparison, a single-anode part in the same package has an ESR of 100mohm. For the E-case device (which has the same footprint but a bigger case size), the minimum ESR is 80mohm.

By reducing ESR by 30 per cent, the new capacitors offer an improvement in filtering capabilities, even to the extent that one part can sometimes replace two standard single-anode devices. Also new in the TPM range, the company has released mirror-design multi-anode parts rated at 35V. The TPM D 22uF/35V is suitable for use in circuits with high currents and voltage spikes where the profiles are limited to 3mm.

It is particularly suitable for automotive battery applications running on 12/14V with very low impedance, where it also offers greater robustness and a lower ESR than single-anode capacitors. Since D- and E-case sizes use an identical footprint, the pad design does not need to be changed if the D-case part can be used to replace the larger capacitor. For higher operating voltages, the TPM D 10uF/50V with an ESR of 140mohm is also available. All parts meet the requirements of AEC-Q200, which is said to be a key requirement for automotive designs in Europe.

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.
