DC-DC Converter Suits Compact Digital Equipment

Suitable for use in mobile devices, such as digital cameras, Taiyo Yuden's BRHL2518 wire-wound chip power inductor is a compact DC-DC converter that enhances power-conversion efficiency. Measuring 2.5 x 1.8mm with a maximum height of 1.5mm, the BRHL2518 reduces volume by approximately 65 per cent and enhances DC-DC converter efficiency by about five per cent when compared to Taiyo Yuden's CBC3225T2R2M Series, which measured 3.2 x 2.5 x 2.5mm.

The BR Series' efficiency is achieved through use of single-sided electrode terminals, new core design and the prevention of increased DC resistance through a reduced size. The incorporation of alternative materials in the BRHL2518 has also improved its high-frequency characteristics. The BRHL2518 features low DCR ranges from 0.055-0.245 Ohms. Saturation current is 1,500mA and inductance is 2.2uH.

Operating temperature is specified at a range of -25C to +105C. It meets today's demands for a reduction in size and an improvement in energy efficiency of many digital devices, including mobile devices, compact digital equipment, digital cameras and portable music players. The BRHL2518 sample price is USD0.20 (GBP0.12) per unit.

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.
