The AEC-200 Y2 class interference suppressor capacitors by Cornell Dubilier that meet a 2,000 hour THB (temperature, humidity and bias) life test are available from New Yorker Electronics. The MYH series were subjected to 2,000 hours THB testing at 85°C, 85% relative humidity at rated voltage, which is twice the industry standard test hours required to meet IEC 60834, Class ...

Capacitors are among the simplest of electronic components – in theory – but the practical implementation is becoming more complex, says Christian Merkel. Capacitors are two conducting plates, separated by an insulating dielectric layer. They hold charge when a voltage is applied to them and give up that charge when the charge-carrying electrons are given a route to flow off ...

Electrocube has created a series of metallised polypropylene film capacitors for high power inverters in military and commercial, land and sea, applications. Voltage ratings of 400, 600 and 1,000V are available, and capacitances from 100nF to 10μF, plus 15 and 20μ in the 400V range “Able to handle high surge currents without degrading, Electrocube’s 985B is a rugged, non-inductively wound ...

Rohm has developed its first silicon capacitors, the 400 x 200 x 185μm ( 01005, 0402 metric) BTD1RVFL series which covers 100pF to 1nF. “The mounting area is reduced by approximately 55% over general 0201 [0603 metric] products to just 0.08mm2.” according to the company. “Moreover, a built-in transient voltage suppressor protection element ensures high ESD resistance.” They are rated ...

At 160µm tall, Murata is claiming to have the thinnest automotive-rated 1µF capacitor, which also measures 0.5 x 1mm. To reduce inductance, it has its terminals along the long sides – so called ‘reverse’ construction. Rated at 2.5V and having a maximum height of 180µm, LLC15SD70E105ME01# is one of only two membeds of a new family that the company has ...

Samsung Electro-Mechanics is aiming at automotive powertrains and safety systems with a 10µF 50V MLCC (multi-layer ceramic capacitor) in 3.2 x 1.6mm 1206 packaging. “Thanks to the application of proprietary ceramic and electrode material atomization, alongside ultra-precision lamination, the company was able to create the 10µF MLCC in 1206 size at 50V rating,” according to the company. “Importantly, the new ...

Cornell Dubilier Electronics is aiming at harsh environments with a series of X2, EMI-RFI suppression capacitors. “The MXH series is AEC-Q200 qualified and has been temperature, humidity and bias (THB) life tested. “The 2,000-hour test conducted at 85°C, 85% relative humidity at rated voltage subjected these components to twice the standard test hours required to meet IEC 60834, Class III-B ...

Schaffner is aiming at robots and other industrial applications with a range of three-phase mains interference filters. “FN3040, FN3041, FN3042 and FN3043 EMC filters are rated for currents of 10 to 30A at 50°C,” according to the company. “The tight-packaged filters are smaller than their predecessors yet offer superior performance.” Size is 128 x 63 x 50mm tall for the ...

CUI Devices has introduced a line of potentiometers with a rotational life of 10,000 cycles and track resistances from from 1kΩ to 2MΩ. PT (photo left) and PTN (right) potentiometers, as they will be known, have shaft-less or shaft-inclusive, and panel-mount or soldered through-hole PCB-mount options. Other options are linear, logarithmic, or reverse logarithmic tapers, mechanical angles of 235, 265, ...

TT Electronics today announced its TFHP series thin film, high power chip resistors which combines high power and high precision in a single resistor, capitalising on aluminium nitride (AIN) ceramic substrate with nearly six times the conductivity of alumina. This high power density component saves printed circuit board (PCB) area and can boost reliability by restricting the temperature rise in ...
