Current Sense Resistors from Ohmite
Using metal resistive elements made from Nickel-Chromium or Cupron (Manganin-Copper) the new MCS Series of SMD flip chip resistors from Ohmite have a very low TCR of <50ppm/°C over the range of current sense values which are popular in portable, battery operated equipment and power supplies.
Power Integrations’ New SENZero High-Voltage ICs Eliminate Sense Resistor Power Losses in Standby Mode
Power Integrations (Nasdaq: POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today introduced SENZero, a family of ICs that disconnect sense resistors from high-voltage rails during standby or remote-off conditions. SENZero devices eliminate sense resistor power losses in standby mode and reduce total system power consumption, helping to meet the stringent demands of energy-conscious equipment makers an...
New power resistors feature high performance levels at lower costs
Recently added to Tyco Electronics’ CGS range of power resistors, new aluminium housed THS series power resistors are based on the high performance HS series devices, featuring same basic performance levels but at lower costs.
Aluminium enclosed resistors from Tyco Electronics
New CJT series resistors from Tyco Electronics feature high IP ratings of IP33 up to IP54, making the devices superior to conventional ceramic resistors when used in harsh environments. Benefiting from easy airtight fitting and the ability to fit a heatsink, the resistors are ideal for inverter braking, as well as loading and charging circuits in harsh environmental conditions.
Metal oxide resistors from Tyco Electronics
Now available from Tyco Electronics is a range of highly stable and reliable metal oxide resistors providing high power in a small package. New RR series resistors are ideal for pulse applications in adverse conditions and are available in three different sizes with power ratings of 1, 2 and 3W for a voltage range from 350 up to 750Volts. Highly temperature resistant the devices feature a resistance range from 0.22Ω up to 1MΩ.
3 x 3mm Step Down Buck Regulator switches 1MHz
Switching 1MHz with a free running internal oscillator, the new LX1918 step down buck regulator from Solid State Supplies is housed in a 3x3mm package which provides designers with an ideal component for use in high efficiency embedded solutions.
NEW CLIP MOUNTING METHOD DESIGNED FOR OHMITE’S TK/TN RESISTORS IS THERMALLY SUPERIOR
A new method of heatsinking has been developed by Ohmite which is proving popular with design engineers because it solves the problem creating a gap if the screw is overtightened when installing conventional TO-220 resistors and creates optimal thermal transfer between the resistor (or semiconductor) and the heatsink.
16mm Stainless Steel Pushbutton Switches
The first of Bulgin's new range is a compact switch extending less than 21mm behind the panel. These single pole, momentary, push to make switches are rated at 2A, 48Vdc and are capable of 100,000 operations at full load and 1,000,000 mechanical operations. There are three button styles; flush, domed and prominent, and all switch variants have screw terminals. The MP0042 is manufactured in stainless steel with a polished finish. The MP0044 is man...
