TDK has introduced a series of high-value metal-framed multi-chip ceramic capacitors for automotive electric power trains, on-board chargers and wireless power transfer systems, where the capacitors must handle high currents or voltages, or have high capacity. “To meet these needs, TDK developed the CA series, the largest MLCCs in the industry [6 x 5.6 x 6.4mm] with a metal frame ...
Kyocera AVX has released low-ESR C0G/NP0 dielectric RF MLCCs (multi-layer ceramic chip capacitors) “inspired by communications market demand for smaller RF capacitors that deliver repeatable performance”, it said. Called KGU, they come in values from 0.1 to 100pF with tolerances as low as ±0.05pF. They come in four chip sizes: 01005, 0402, 0603 or 0805 (EIA). Class I C0G, also ...
Nanusens has demonstrated a mems digitally-tuneable capacitor for 5G and 6G RF front-ends, that is compatible with CMOS IC processing and can be integrated with circuitry. The Q-factor is above 100 at 1GHz, and the four-bit capacitor has a minimum capacitance of 450fF (30fF/capacitor) with them all off and tunes up to ~1pF – a capacitance ratio of 2.2 which ...
Vishay has introduced a series of surface-mount solid moulded tantalum chip capacitors specifically for electronic detonation systems “combining a robust mechanical design with low leakage current and stringent testing specifications”, according to the company. “Each part is 100% surge current tested using standard screening methods, and undergoes two additional screenings for key electrical characteristics to eliminate lot-to-lot variations.” Called TX3, ...
Samsung has created a 630V 100nF multi-layer ceramic capacitor in 1210 size (3.2 x 2.5mm) specifically for electric vehicle dc-dc converters and on-board chargers. CL32B104KHU6PN has an X7R dielectric (±15% capacitance -55 to +125°C) and a maximum rated voltage of 630V. “A dc-dc converter converts high voltages to 12Vdc in order to operate in-vehicle infotainment systems, for example,” according to ...
Empower Semiconductor is aiming at high-performance decoupling within IC substrates and interposers with its largest silicon capacitor yet, the 16.6μF EC1005P. “The performance of SoCs and other large computing processors are constantly increasing, said Empower marketing manager Mukund Krishna. “It is becoming increasingly difficult to reach the level of power integrity and voltage regulation that these devices require with conventional ...
Kyocera AVX has launched two series of snap-in -25 to 105°C electrolytic capacitors for commercial and industrial applications. SNA capacitors are rated for a life of 5,000 hours. Voltage ratings are 250, 420 or 450Vdc, capacitance is between 82 and 1,500µF (±20%), and there are 24 case sizes spanning 22mm diameter x 25mm long to 35∅ x 50mm. As well ...
Samsung is aiming at electric vehicle on-board chargers with a 1,000v 22nF multi-layer ceramic capacitor. CL32C223JIV1PN# (yes, there is a # in the part number) is aimed at CLLC resonant power supply topologies and is constructed with a COG dielectric. Operation is across -55 to +125°C and it has a ±5% tolerance. Packaging is a 2.5mm tall 3.2 x 2.5mm ...
Panasonic Industry has introduced compact surface-mount electrolytic polymer hybrid capacitors that are “one size smaller than ZC series with the same capacitance” and AEC-Q200 compliant for automotive use, it said. Called the ZL series, the parts come in five case sizes from 5mm diameter (ø) x 5.8mm high (47 or 82μF), to 10ø x10.2mm (470 or 680μF). There are two ...
Sciospec LCR-1 is a PC-based single-channel LCR meter that offers 2-, 3- and 4-port measurements across 100mHz to 500kHz, with 1mΩ – 1TΩ, 10fF – 1kF and 1nH – 1TH capability. Options include upper frequency expansion to 1 or 10MHz, and it comes with PC-based software for automated measurements and analysis, which displays up to four parameters at the same ...
