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 ...

Distributor Rutronik is stocking a 100V multi-layer ceramic capacitor (MLCCs) from Samsung Electro-Mechanics. The part, called CL32Y106KCVZNWE, has a capacitance of 10μF and uses an X7S dielectric to get it into a 3.2 x 2.5 x 2.5mm package. Rutronik is promoting it for use on 48V power rails, where companies are switching up from 12V to increase power efficiency. “The ceramic ...

Sumida’s CDRH12D78E/LD is a 12.5 x 12.8 x 8mm magnetically shielded power inductor family. The parts are “ideal for DC/DC converters such as a buck-boost, SEPIC [single-ended primary-inductor converter] and zeta for non-automotive applications”, according to distributor New Yorker Electronics, which is stocking the parts. “This new model is an upgrade to the CDRH127/LD,” it added. There are twenty-three variant with ...

TDK has created two series of capacitors specifically for power factor correction (PFC). Jointly-branded PhaseCap Energy Plus, the series are: B25674C – gas-impregnated, 230 to 690Vac, 5 to 33.1kvar compensation B25675C – biodegradable resin impregnated, 230 to 1,000Vac, up to 60kvar compensation Lifetime is up to 240,000 hours in temperature class -40/D, the terminals are class IP20 touch-proof, and ceramic-based discharge resistors ...

Tecate has added 3V supercapacitors to its TPLH series of otherwise 2.7V parts, designed for long life and high-temperature high-humidity use. “The new series provides the pathway to higher voltage and greater energy density within the same industry-standard cell footprints,” according to distributor Omni Pro, which is stocking the parts. “Technology improvements are a direct result of propriety innovation in ...

Stackpole has introduced surface-mount resistors with terminations on their long edges to improve thermal conductivity. “One of the most common and economical options for reducing the effects of high power is wide terminations,” according to the company. “By reversing the geometry of the chip resistor and applying the terminations to the long sides of the part, the hot spot temperature ...

Vishay has announced 0805 SMD resistors that combine 450V operation with ±0.1% tolerance and a temperature coefficient as low as ±10ppm/K. They are the TNPV0805 e3 series, introduced as part of the greater TNPV e3 series (table below) of automotive high-voltage thin-film flat chip resistors. “Typical applications for the AEC-Q200 qualified device will include voltage measurement in automotive and industrial inverters, voltage dividers ...
