Avago Technologies today announced two new miniature voltage/current threshold detection optocouplers for use in a wide range of industrial control applications. The ACPL-K370/K376 optocouplers are designed to detect AC/DC sources and convert the voltage to a logic interface across an optical coupling barrier to provide safe isolation in electronically noisy environments found in industrial applications. These voltage/current sensing optocouplers...

Maxim has introduced the MAX14523A/MAX14523B/MAX14523C, a family of adjustable current-limit switches. These overcurrent limiters offer a ±10% accurate current limit that can be programmed from 250mA to 1500mA with an external resistor.

Vishay Intertechnology today announced that it has extended the resistance range of its E/H MIL-PRF-55342-qualified thin film resistor chips in the compact 2208, 2010, and 2512 case sizes. Allowing for lower resistance values in high-reliability applications, the enhanced devices feature ratings down to 49.9 Ω at ± 25 ppm/°C TCR and a 0.1 % tolerance, and 10 Ω at a 1.0 % tolerance.

Vishay Intertechnology today announced a new series of 1500-W surface-mount TransZorb® transient voltage suppressors (TVS) with an industry low profile of 1.1 mm. The SMPC series offers breakdown voltages from 6.7 V to 42.4 V and excellent clamping capability from 10.0 V to 58.1 V.

Vishay Intertechnology today announced a new economical, long-life panel potentiometer featuring up to four modules and a compact 12.5-mm size. While standard low-cost panel potentiometers reach 50,000 cycles, the P11L offers a long life of 2 million cycles. For designers, this reduces the need for replacement parts, increasing reliability and lowering maintenance costs.

Avago Technologies claims the industry’s most energy efficient 1MBd digital optocoupler. Avago’s compact low power ACPL-M50L single channel optocoupler, which operates on approximately 80 percent less drive current than today’s standard 1MBd digital optocouplers, targets designers of communication interfaces, microcontroller system interfaces, switching power supplies, and digital isolation for A/D, D/A conversion applications.

TTI Inc., is now stocking a new range of devices for the ESD protection of data, audio and video lines (e.g. USB, Ethernet, IEEE 1394 and HDMI), analogue and digital connections, ICs and inputs/outputs in electronic equipment. CeraDiodes - ceramic multilayer semiconductor components from Epcos - are a cost-effective alternative to ESD protection components based on semiconductors such as Zener and TVS diodes, and are also, claims TTI, technically...

Designed specifically for USB 3.0 applications, Taiyo Yuden’s new CM01S600 Common Mode Choke Coil is the first in the industry to deliver a 10 GHZ cut off frequency. A 25% higher cut off frequency improvement (compared to previous products) is achieved through the CM01S600’s use of an extremely precise wire-wound structure. A higher cut off frequency is especially necessary with the improvements in USB technology.

CUI Devices has announced that its C14 panel mount optical encoder is now available with optional IP65 protection to prevent dust and water intrusion. The C14 series offers a 2-bit quadrature resolution with a very clean square wave output signal. Possible applications include industrial equipment, portable communication equipment, and medical equipment, or as a replacement for a panel mount potentiometer.

The surface mount SM501-1 Transformer is suitable for a wide range of BS6305 Impedance Class A non-speech data and Class B voice applications in telecom equipment, laptops, modems, instrumentation and more. Its dielectric strength is tested to 4600 Vrms and meets various international safety standards including UL60950-1.
