Long profile female headers

Printed circuit boards are stacked to keep the overall design in electronics applications as compact as possible. Connectors also help to save space: An additional component is superfluous by using long profile female headers. They also protect the contacts from being touched, bridge different heights and provide additional space between the boards.

Diotec: Cost Effective Yet Powerful Load Dump Protection Diodes

Especially in applications without centralized load dump protection, such as several motorbikes, a powerful yet cost effective load dump protection of distributed board electronics is desirable. The typically used package outline DO-218AB is offering a high performance, but is limited to load dump TVS devices and runs therefore in lower volumes only, causing higher device costs. The D²PAK offers a similar case outline but is an absolute industry standard package, used for high volume devices like Rectifiers and Schottkys.

W+P: Rj45 network cable connections in many variants

Attributes such as stable, failure-free, secure, fast and low-loss optimally describe the advantages of wired network connections. They are indispensable in buildings, in private surroundings or in office environments.

With the Series 660, W+P is expanding its range of pre-assembled network cables with an extensive selection of models and lengths, in various colors upon request. This means, that long transmission paths can be overcome with low losses. 

W+P: Low component height in a small pitch

Connecting printed circuit boards in limited space is a challenge in electronic applications. This requires connectors in small pitches and low heights.

The new SMT female header series 6067 has exactly these characteristics. Additionally it is pluggable from above, with a 1.27mm pitch. The two selectable heights are specified as 3.60mm and 4.50mm.

New ROHM Building in Chikugo: Expanding Production Capacity of SiC Power Devices

ROHM has recently held an opening ceremony announcing the completion of a new building at ROHM Apollo's Chikugo plant to enhance the production capacity of SiC power devices. The new building is a state-of-the-art environmentally friendly factory that introduces a number of energy-saving technologies to its production facilities, with 100% of its electricity coming from renewable energy sources.

Diotec: SM3000 High Voltage SMD Diode

The latest development of Diotec addresses this requirement. The SM3000 in Plastic Melf offers the impressive repetitive reverse voltage of 3000V at 1A of average forward current. It allows design engineers to develop cost and space solutions by replacing the ususal series connection of two lower voltage types.

Central: 4.0A, 1000V Bridge Rectifier in BR DFN-A package

Central Semiconductor’s CBRDFA4-100 is a 4.0 amp full wave bridge rectifier mounted in a durable epoxy surface mount BR DFN-A case, utilizing glass passivated chips. Ideal for low profile power supplies and fast chargers in consumer, industrial, scientific, and medical applications.

W+P: Compact SMT B-t-B connector with 1.27mm pitch

Every millimeter inside electronic units is precious, because a compact interior must be functionally accommodated in the smallest of spaces. W+P delivers the intelligent answer for precisely these limited spatial conditions.

Variable PCB orientation

The Board-to-Board connector series 9025 and 9026 with 1.27mm pitch are characterised by compactness, flexibility and reliability. They represent an expansion of the W+P range of PCB-to-PCB interfaces, which meet the growing demand for a low number of contacts with a small pitch.

W+P: Stable hold thanks to locks on the housing

Connector housings essentially fulfil two functions: They ensure a reliable connection between plug and mating part and protect the connector and its inner-life from mechanical, electrical and thermal influences. 

Housings can do even more - thanks to their coded design, they guarantee reverse polarity protection and optional strain reliefs intercept e.g. high forces to protect the cables. In addition, housing locks provide components with a solid hold against unintentional disconnection - thus the most varied types with their interlocking mechanical fixtures ensure reliable fastening.

W+P: Connectors with circumferential housing shielding

W+P offers shielded connectors as protection against unwanted electromagnetic influences, in order to meet the interference-free signal and current supply requirements of the industry.

The shielding of the series 5692 is achieved by a circumferential metallic housing made of steel, which is connected with a clip to the insulator of the pin header. This shielding plate, which is already integrated, is soldered directly to the PCB and its design satisfies the requirement for the protection of surrounding areas. This means that sensitive signals can be transmitted with low interference and also received just as clearly.
