In addition to LEDs and LED displays by Liteon, distributor TME has announced a variety of optoelectronic components. The components are made for galvanic isolation up to the high kV range by enclosing a transmitting LED and a phototransistor in a single package for the signal to be transmitted optically between them. For use in drivers and communication devices to ...

Automotive precision 0402, 0603 and 0805 surface mount resistors
Vishay has extended its Automotive precision resistor range in 0402, 0603 and 0805 case sizes, which now rub up to 7.5MΩ with ±25ppm/K temperature resistance and ±0.1% tolerance. MCS 0402 AT, MCT 0603 AT and MCU 0805 AT offer values from 47Ω to 1 MΩ, 2MΩ and 7.5MΩ respectively. “They join the previously enhanced MCA 1206 AT, which offers resistance ...
Thermal trips protect power semiconductors at 175°C
Schurter has added a low-trip-temperature variant to its RTS thermal fuse range, originally launched in 2018. Rather than >210°C, they are rated at >175°C. They have been developed to protect power semiconductors from over-heating – particularly from thermal-runaway when the semiconductors are in a confined space. In such an event, the thermal fuse interrupts the circuit, now from as early as ...
Surface-mount power resistors reach 2W in 1020 size
TT Electronics has expanded its WHPC series of surface mount power resistors to include 1W (WHPC0508X), 1.5W (WHPC0612X) and 2W (WHPC1020X chip) sizes. These are the same size as the company’s similarly-sized parts without the ‘X’ suffix, but can handle more power – ‘X’ stands for extra high power. The earlier (non-X) 0612 and 1020 can handle 0.5W and 1W respectively. “Ideal for power ...
Panel potentiometers are stiffer to resist accidental rotation
Vishay has introduced panel potentiometers that are stiffer to rotate, to reduce the chances of operation accidentally or though shock or vibration. Behind the panel, the bodies are 12.5 x 12.5mm, and they are modular, allowing up to seven potentiometers to be stacked on the back of a single shaft. Various switch modules can be included. Operating torque is typically ...

A ”smart automation warehouse” enables complete visibility, reduces complexity, improves operational performance, increases the productivity process in the industry by operating smart machines including robots, AGVs, RGVs, carton shuttle, forklift, etc. These devices are typically powered by batteries or cables or trolley wire, which require charging regularly, a place to charge as well as maintenance. And for outdoor systems ...
3.5W current sense resistors in 2512 SMD package
Stackpole Electronics is aiming at consumer and industrial electronic devices with a surface-mount 3.5W current-sensing resistor. Called CSRT2512-UP, it comes in a 2512 case size – 6.3 x 3.2 x 0.7mm. “The AEC-Q200 compliant CSRT2512-UP has unique thin film material properties and processing to provide higher continuous power ratings and higher pulse power ratings than other thin film chip resistors,” according to ...
CAT6a data line and PoE EMI filters
ITG Electronics of New York has introduced Cat6a and Power-over-Ethernet EMI filters for shielded MRI rooms. Called F2780Y001L-001 (see photo), it is 200mm long and has RJ45 male connectors on each end for easy connection to switches, routers and computers. Inside are eight identical two-stage CLCLC filters (see diagram), offering noise attenuation of 50dB from 30 to 70MHz, 100dB from 100MHz ...
Non-magnetic RF inductors for medical imaging, and other tricky magnetic environments
Gowanda Electronics has introduced a series of non-magnetic RF inductors for medical imaging equipment – MRI and some x-ray machines – and other applications where magnetic materials must be avoided. Called 28MG, there are 60 devices spanning 1.2 to 18µH with resistances between 79mΩ and 4.15Ω, and carrying capacity of 315mA to 2.4A. They are all the same size, with bodies 23mm ...
Teflon high film capacitors can tolerate up to 150°C without derating
Two high temperature film capacitors by Electrocube can be used in high temperature applications. The 433D and 463D foil capacitors are manufactured using Polytetrafluoroethylene (PTFE or Teflon) for extreme heat protection. The 433D series is Teflon and foil and the 463D series is metallised Teflon. The capacitors are available from New Yorker Electronics. The capacitors are optimised for high temperature applications ...
