TT Electronics has launched a new range of surface mount (SMT) power inductors for high frequency and high temperature applications. Named the HA65A series, the inductors are designed to meet the requirements of the growing automotive market’s need for certified, high power inductors specifically for buck, boost or buck-boost power converter topologies for optimum voltage […]
Resistors
Top power electronics threads on EDAboard.com – October
Industrial grade robust inverter build – I have done a lot of research online about IGBTs, gate drivers, blown up many IR2110s, studied PCB layout considerations, OC/SC protection, current sensors and so on but none of my designs has ever lasted for long when loaded by an actual motor. The waveforms were perfect, but smoke was […]
SLN3 molded current sense resistor offers 3-W power rating
KOA Speer Electronics introduces the new SLN3 molded current sense resistor, featuring a 3-Watt power rating in 4528 size. The molded resin resistor provides excellent dimensional accuracy, mountability and shock resistance. Due to its metal plate terminal electrode, it also offers excellent terminal strength, heat and shock resistance and solderability. KOA Speer’s SLN3 resistor has […]
Working with Wirewounds
by Kory Schroeder, Director of Product Marketing and Engineering, Stackpole Electronics Inc. For high currents, axial-leaded wirewound resistors are often good candidates because they can handle up to 10 W and double as fuses. When a task calls for dissipating kilowatts of power over an extended period, wirewound resistors are often a logical choice. These […]
Current-sense resistors handle 2 W
KOA Speer Electronics introduces the new TLR2HW metal plate chip current sense resistor in a 2010 size, featuring a 2-watt power rating and ultra low resistance of 1m to 10m. The metal alloy of the TLR2HW provides superior corrosion and heat resistance, with small size SMD type metal plate providing low resistance for current detection. […]
Low Resistance Values Ideal for Portable Consumer Electronics
The CSRF Series is a surface mount current sense resistor series that utilizes foil on ceramic carrier technology. This structure allows for very low resistance values in small case sizes while maintaining good TCR. The 0402 size is available in the popular 10 milliohm value, while the 0603 size is available in values down to […]
TI’s ultra-small FemtoFET™ MOSFETs Feature Lowest On-Resistance
Texas Instruments (TI) (NASDAQ: TXN) introduced the industry’s smallest, low on-resistance MOSFETS for space-constrained handheld applications, such as smartphones and tablets. The new family of FemtoFET™ MOSFET transistors features ultra-small packaging and on-resistance below 100 milli-ohms. The three N-channel and three P-channel FemtoFET MOSFETs are packaged in a land grid array (LGA) that reduces board […]
Stackpole’s ASRM2 2-Watt Resistors
Stackpole’s addition of ASRM2 is a mini 2 W power rating in its ASR series of axial leaded anti-surge resistors. It is the same size as the ASR1, has the same working voltage rating of 4 KV and overload voltage rating of 5 KV, yet rated for 2 W of continuous power. The ASR series […]
The Laminex EMI/RFI Shielding Tape and Flat Conductor
With no adhesive layer, the Laminex EMI/RFI shielding Tape and Flat Conductor windings offers three distinct advantages over its competition. It is thinner overall for a given dielectric strength, still using a thicker conductor; customers can solder lead wires to the base metal right through the insulation film; and, customers’ cutters and taping machines never […]
High Power to Size Ratio from Super Mini Metal Film Resistors
Stackpole’s flameproof RNS Series is ideal for existing designs that require downsizing or added features. It is also a popular choice for new designs that require the smallest form factor possible for a given power rating. Specifically, the RNS Series 1W has an EIA standard ¼ watt body size, and the RNS 2W has an […]
