Stackpole has released the NWWP series axial leaded wirewounds that provide good anti-surge characteristics in a non-inductively wound design. The Ayrton-Perry winding greatly reduces inductance to a fraction of what a standard winding would provide while the robust wire design maximises element mass for exceptional energy handling.

Metal Foil Chip (MFC) resistors from TT Electronics use metal foil on ceramic technology, which combines the heat spreading properties of a ceramic substrate with the surge tolerance of a bulk metal alloy resistance element.

United Chemi-Con’s newest SMD Polymer Aluminum Electrolytic Capacitor are in stock at distributor New Yorker Electronics.

Power supplies and power controls have a wide range of sensing requirements. For applications that require high sensing precision and high power where the element TCR is more important than low resistance values, the CSRT2512-UP offers a 3.5W rated current sense chip resistor in a package that normally only allows for one or two watts.

New Yorker Electronics has released Exxelia’s new 253P Series of Wrap-and-Fill High Temperature PTFE Film capacitors.

Power electronics that utilise current sensing resistors for power control have a wide range of typical requirements. For those applications that require high power handling with low self-heating and high surge currents, the HCS high current SMD shunts from Stackpole are a good choice.

New Yorker Electronics has released Vishay’s newly extended EP1 Wet Tantalum Capacitor, supplying the industry’s highest capacitance per voltage-rating for this device type.

New Yorker Electronics has released the new Cornell Dubilier DSF Series of high voltage and high energy density supercapacitors.

High efficiency current sensing requires low resistance values to minimise wasted power. As applications downsize, engineers are challenged to find lower resistance values in small case sizes. Stackpole has announced that it now offers the CSSH0805. This all-metal 0805 case size is capable of dissipating up to one watt of power at resistance values 0.5mΩ.

A new series of metal element current sensing resistors from KOA which offer high precision and reliability for demanding applications are available at Anglia Components.
