100V 10μF MLCC in 1210

Rutronik Samsung MLCC 100V

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 improves 12.5mm inductor offering

NewYorker Sumida Inductor CDRH12D78E

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 ...

Capacitors for power factor correction

TDK Epcos PhaseCap Energy Plus 2022

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 ...

3V supercapacitors work up to 65°C and deliver amps

Tecate_Group_TPLH_Ultracapacitor

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 ...

Side-terminated SMD resistors handle up to 3W

Stackpole High-power RMCW HP

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 ...

Thin-film high-voltage automotive resistors in 0805

Vishay TNPV0805 e3 automotive resistors 683

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 ...

Automotive high-current flat wire inductors

ITG L201316D-110MHF inductor automotive

ITG Electronics has introduced a line of high current flat wire inductors for automotive and industrial environments. Called the L201316Q series, it offers nine inductance choices from 1.00μH to 105μH, and emphasises high current capability with examples of 75A for the 11.6μH part and 25A for the 105μH inductor. These are both 30% inductance drop figures at 25°C. The 20% drop ...

Tough automotive wirewound resistor for electric vehicles

Vishay MCB HRHA automotive wirewound

Vishay Intertechnology has introduced an AEC-Q200 qualified charging resistor “that is the industry’s first such device to feature hybrid wire-wound technology in a standard package size”, it said. “Typically, designers must utilise several thick film resistors to meet the high pulse requirements of these applications.” The parts, called HRHA, can handle 6kJ for 300ms and operate across -55 to +250°C. The ...

Bluetooth indoor positioning antenna

u-blox_ANT-B10 positioning antenna

U-blox has created an indoor positioning antenna for Bluetooth, designed to be built into end-user products. Bluetooth indoor positioning uses the angle-of-arrival of a signal to at several fixed points in a room. The signal is emitted by the mobile entity to be tracked – a Bluetooth tag, for example. Location is measured to sub-metre accuracy in real-time, according to the ...

Automotive three-terminal capacitor packs 4.3μF into 0.5mm2

Murata NFM15HC435D0E3 three terminal capacitor

Murata has managed to compress 4.3μF into a three-terminal 0402 (1005 metric) package, and qualified it for automotive use. This is the surface-mount equivalent of a feed-through capacitor, with the end terminals connected together by a low-resistance direct path. This path is one end of the capacitor, whose other end is to be grounded via the centre terminal (which looks ...
