Vishay

Did you ever dream of surface-mounting wire-wound power resistors? If you do, Vishay has turned that into reality with a series of pick-and-place-friendly cemented wire-wounds. They are actually the company’s existing 3W AC03-CS series of fuseable resistors, with the legs bent into what the company is calling its WSZ lead-form (see photo), available from 1Ω to 100Ω ±5%, with ±200ppm/°C ...

Vishay has released a digital ambient light sensor in a 4.38 x 1.45 x 0.6mm package, with AEC-Q100 qualification for automotive use. VEML4031X00, as it will be known, has a visible light spectral sensitivity designed to match the human eye, and also includes an ambient infra-red sensor for light source differentiation. “With an ambient light range from 0 to 172 ...

Vishay has introduced a 5A 30V solid-state relay in a SOP-4 surface-mount  package. VOR1003M4T is an industrial-grade relay with a 1 Form A (single-pole normally-open) contact. On the output side there are back-to-back mosfets allowing ac or dc to be switched. Typical output-side figures are: 0.7Ω Rds(on), 500μs Ton, 100μsToff and <1μA leakage. These switching times are with 10mA drive ...

Vishay has created a fast opto-coupler that can operate at 25Mbit/s. Called VOIH72A, is has a digital buffering on the input and output. “The component combines a maximum pulse distortion of only 6ns, a maximum supply current of 2mA and a supply voltage range of 2.7 to 5.5V, and is fast enough to support bus systems such as SPI, as ...

Vishay is claiming industry’s lowest Rds(on).Qg and Rds(on).Co(er) figures-of-merit for its latest 650V super-junction mosfet. The typical figures are 3.74ΩnC and 8ΩpF respectively. SiHK050N65E is an n-channel device aimed at power factor correction and subsequent dc-dc converter blocks up to 6kW. Typical on-resistance is 48mΩ (25°C, 10Vgs) and gate charge can be 78nC (16A, 520V, 10Vgs). “The device addresses 200 ...

Vishay has introduced 1, 2 and 3kV multi-layer ceramic capacitors for commercial applications. In seven case sizes from 1206 to 2225, they are made with either C0G (NP0) or X7R dielectric. C0G types are rated at 2kVdc or 3kVdc and come in values between 1.5pF and 82nF, with a temperature coefficient of 0±30ppm/°C from -55 to +125°C. X7R types are ...

Vishay has revealed a high-speed and high-precision inductive rotational position sensor. As the device, RAIK060, uses induction, it “isn’t sensitive to magnetic environments, allowing it to be used close to electrical motors”, according to the company. The specs are impressive: Up to 10,000rpm rotational speed, with custom versions going higher, and 0.044° (≥13bit) accuracy at 25°C with ±1 LSB output ...

Farnell is stocking the band new microBRICK regulator module from Vishay Intertechnology, expanding its power portfolio with the smallest DC/DC regulator module on the market. micoBRICK is a synchronous buck regulator module with integrated power MOSFETs and an inductor. It can supply 20 A of continuous current at up to 2 MHz switching frequency. The regulator produces an adjustable output ...

Vishay has announced 1A and 3A 1,200V hyperfast rectifiers in 4.2 x 1.4 x 1.08mm SMF (DO-219AB) packaging with a minimum of 2.2mm creepage. Of the four FREDs (fast recovery epitaxial diodes), two of them are automotive grade and the others are for industrial use: VS-E7FX0112-M3 and VS-E7FX0212-M3 for industry, and VS-E7FX0112HM3 and VS-E7FX0212HM3 for vehicles (see table below). “The ...

Vishay has introduced an automotive-rated series of positive temperature coefficient (PTC) in-rush current thermistors that can absorb up to 340J, designed for dc link charging and energy discharge circuits. Called PTCEL67R, they are through-hole disc devices, available with 25°C resistances (R25 values) from 150Ω to 1.5kΩ and handling up to 1.2kVdc. They can handle 180J at 85°C and 130J at ...
