Successfully diminishing the difference between the effective permeability and the initial permeability in a practical core, the H5C3 ferrite core material provides an excellent permeability reaching 13,000. This enables drops in size. The material is at work in the EP-style core. During manufacturing, sinter technology minutely controls the crystal structure of the H5C3 while maintaining excellent frequency characteristics. The H5C3 material has excellent temperature characteristics with a temperature coefficient of -0,5 to 1,5 (-30 ± 70˚C), improves the frequency characteristics in the high and low bands, reduces the insertion loss and operates in the temperature range of 0˚ to 40˚C.

For use in broadcast and communications satellite receivers, the series of microwave local oscillators feature the smallest, lightest designs in the industry, weighting 4.4 g and measuring 7.5 mm tall. They offer a 1.9 cc volume. There are six models; samples are available. This one operates at 10.678 GHz. The 2nd covers 11.200 GHz, the 3rd works at 11.300 GHz and the 7th accommodates 10.750 GHz. The 8th works at 10.873 GHz, the 9th handles 10.990 GHz. The excellent performance eliminates the need to adjust the high frequency. As a whole, the modules make it possible to create a miniature outdoor unit for satellite broadcasting. They are suitable for converters in flat antennas, and mount easily on converters.

To protect an IC from static surge invasion, the Emi Guard electromagnetic interference (EMI) filter provides a surge-absorbing function. Use of a proprietary three-terminal capacitor structure for the varistor allows it to absorb the static surge that invades the I/O pins of a semiconductor IC; this prevents IC destruction. ICs that static surges of 1 kV normally destroy will withstand static surges of 15 kV. The filter provides a static capacity of 130 pF + 20 per cent (at 1 kHz), a DC resistance of 200 to 500, a rated voltage of dc 25 V, a rated current of DC 20 mA, a surge withstanding current of 15 A (twice in 8/20 µs) and operating temperature range of – 25 to 85˚C.

A phase monitoring relay which ignores momentary voltage or phase failure has been launched by Carlo Gavazzi Electromatic.
Designated the Electromatic S-System Type 5074, the relay was developed as a result of frustrations in the British water industry where monitoring relays had the costly and annoying feature of switching alarms or shutting down equipment when a mere momentary loss or reduction in voltage of a phase was detected. The Electromatic solution has been to build a delay on de-energise timer into the relay unit so that a 10 second delay is experienced before the relay points release.

For large-screen and wide-screen TVs, the sockets come with double-focus gaps. The socket works from 29.1 to 32.5 mm and base pin circles of 15.24 mm. To save time in connection, the sockets come with two high-voltage wires that offer a snap-in format. Engineers can remove these wires from the socket easily, for maintenance. At the same time, the compact design saves space in board mounting. With a DC 20 kV/min. withstanding voltage, the socket offers an insulation resistance greater than 10,000Ω at DC 1 kV. The spark discharge start voltage equals DC 14 to 17 kV for the number 1 and 2 pins, DC 1.2 to 2.4 kV for number 8 pin, and DC 1 to 2.2 kV for the number 6, 7, 9, 10, 11 and 12 pins.

Geotracer System is a complete GPS surveying system for all types’ applications.
Developed for surveyors by surveyors it’s system you can count when the highest accuracy is required, or in areas near buildings and trees, in tunnels and under bridges.
Rugged and ergonomic, with a user interface and method of working, it is designed to make you feel at home.
Initial results are presented within 3 seconds with updates 4 times a second. That means you can use GPS in setting out and collecting detail. Based on the same modular upgrade concept as geodimeter System 600, you decide when to move up and how far.
Surveying… is maximum productivity in every situation.
