Miniaturized Solid State Relays

Miniaturized Solid State Relays
Avago Technologies has announced an expansion of its solid state relay (MOSFET) family of opto-isolation products. The company is a leading supplier of analog interface components for communications, industrial and consumer applications. With input drive as low as 2mA and fast switching speeds of less than 0.5ms, Avago's new ASSR-301C/302C and ASSR-401C/402C are specifically designed for sensing and multiplexing applications, such as test and measurement and data acquisition systems, where low power consumption and high system throughput are essential.

High-current rectifier featuring sophisticated heat distribution

High-current rectifier featuring sophisticated heat distribution
The European distributor ECOMAL is now offering the new Shindengen US-KB family of products, which sets new standards in rated and peak current performance. 10, 15 and 30 amp versions have been added to the familiar range of 4, 6 and 8 amp versions. Due to low AC line impedance, rectifiers which are connected to the AC input often have to be protected against excessive inrush current which flows when large are uncharged. An external protective resistor is connected in series with the rectifier, and the maximum current rating is an important criterion for bridge rectifiers.

Electrolytic capacitors with unusual SMD leads offer excellent vibration resistance

Electrolytic capacitors with unusual SMD leads offer excellent vibration resistance
Today’s electronic components have to meet very stringent requirements to ensure that they are able withstand the stress of automotive and other hightemperature applications combined with high levels of vibration. Large electrolytic capacitors which are used to store energy cause problems, as they are the only components with wire leads in many applications. The European distributor ECOMAL has reacted to this situation by adding innovative Frolyt aluminum electrolytic capacitors to its portfolio. This pseudo SMD solution now makes it possible to use capacitors with a case diameter of 18mm in very demanding applications. The pins are bent very precisely so that they lie flat on the SMD pads and can be put through a lead-free soldering process. The visible solder joints can be inspected to verify the quality of the reflow process.

SM-31 smallest sealed 5 turns SMD trimmer

SM-31 smallest sealed 5 turns SMD trimmer
International distributor ECOMAL based in Berkshire, UK announced a further variation of a smallest SMD multi-turns trimmer to its program of Nidec Copal Electronics. The latest model SM-31, is 5 turns smallest SMD trimmer in addition to the existing SM-3, 11 turns and is RoHS compliant and lead-free soldering compatible. Measuring only at 3.9 x 3.9 x 3.2 mm, SM-31 is ideal for applications that have space constraint but requires precise adjustment.

Efficient, low-loss synchronous rectification

Efficient, low-loss synchronous rectification
The European distributor ECOMAL has introduced the first Schottky barrier rectifiers from Vishay Technology which use trench MOS technology. These devices appear in the equivalent circuit diagram as an MOS element and Schottky metal in parallel. New environmental guidelines including EUP (Energy – Using – Products 2005/32/EC), which are intended to save as much energy as possible and minimize the tolerable losses in the overall system, require highly efficient circuit designs.

High performance power shunts for precise measurements of high currents

High performance power shunts for precise measurements of high currents
The new PSI and PSB series power shunts from KOA are particularly suited for the precise measurement of high currents. The rated power of the metal plate design resistors ranges from 3 to 6 watts at 105 °C termination temperature, and some models offer reliability benefits in high temperature and power load cycling environments by a specially designed shape of the landing pads. Typical applications comprise ECUs, inverters, and industrial automation equipment.
