Schottky barrier diodes for low voltage applications

Schottky barrier diodes for low voltage applications
Suitable for use with DC/DC converters and in low voltage applications, particularly in hand-held and portable equipment, the XBS104P11R-G, XBS304F11R-G and XBS306P11R-G Schottky barrier diodes have been announced by Torex Semiconductor. Schottky barrier diodes offer much lower forward voltage drop than standard switching diodes which means that they can offer high current capabilities, ultra fast switching and low power dissipation.

Resistor series extends power rating to 2W

Resistor series extends power rating to 2W
The power rating of the PTN series of resistors, from Vishay Intertechnology, has been extended to 2W. Available in the 2512 case size, the precision surface-mount, thin film chip resistors have been built using the Vishay Dale Thin Film, a self-passivated, moisture-resistant tantalum nitride resistive film technology. This technology combines high power rating with a low absolute TCR of ± 25 ppm/°C and laser-trimmed tolerances down to ± 0.1 % over a wide temperature range of -55 °C to +125 °C.

Resistors' low inductance suited to high frequency operation

Resistors' low inductance suited to high frequency operation
The TFBR series of high power density, low profile thick-film technology high power resistors has been launched by ARCOL Resistors. Designed for easy assembly and supplied with a variety of terminal styles, the thick-film technology, low-inductance design, lends itself to high frequency operation due to its low inductance characteristics. The added benefit of high instantaneous pulse capacity also makes the TFBR suitable for braking, snubbing and discharge requirements.
