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 ...

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 ...

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 ...

Murata is offering a 4V 10μF ceramic capacitor with ±20% tolerance in a 0201 – 0603M package. “They are currently the smallest MLCC products on the market to deliver such capacitance levels,” claimed the company, “representing a 65% size reduction on the 0402 – 1005M products that would normally need to be specified. ” Called GRM035R60G106M, the parts a -55 ...

Kyocera has announced NP0 dielectric MLCCs (multi-layer ceramic capacitors) approved to the Defense Logistics Agency Qualified Products Database (DLA QPD) for high-reliability military applications. “The new MIL-PRF-32535 BME NP0 MLCCs have higher CV capabilities than standard surface-mount PME MLCCs qualified to military and aerospace specifications and are currently available in M and T reliability levels and 0402, 0603, and 0805 ...

In need of a small high-temperature chemical reaction vessel with a lot of detailed features, BASF turned to Bosch Advanced Ceramics and the Karlsruhe Institute of Technology (KIT). Between the three organisations, they developed a way to 3d print what was needed. The result is 107mm long and 16mm in diameter, with 500μm channels in which the chemical reactions occur, ...

Bosch Advanced Ceramics is making Wheatstone bridges to measure deflection in pressure sensors. “It does this permanently and constantly,” said Bosch, “and, unlike electrical insulation or a metal resistor, the signal cannot be distorted with technical ceramics.” The image is a demonstration tile with eight ceramic Wheatstone bridges.

Knowles Precision Devices has added a 100nF capacitor to its V-Series of single layer capacitors. The high-frequency wire-bondable device is suited to GaN and GaAs amplifier applications where small size and microwave performance are critical. “The small footprint, along with X7R temperature stability and wire bondability of the 100nF are integral to a well-performing circuit,” said  said Knowles product manager ...

Knowles is saving space in power supply PCBs by offering edge-stacked ceramic capacitor assemblies. Intended for filtering in the input and output stages of switch-mode PSUs,  the parts are the ‘SV’ series. “The assemblies can be made with up to 10 chips of the same size with various lead configurations to safeguard against thermal and mechanical stresses,” according to product ...
