Oxley Developments has launched a range of Press Fit EMI filters for applications in telecoms, microwave filters and amplifiers.

The filters are claimed to offer an advantage over solder-mounted filters, as by removing the need to solder they simplify and speed up assembly with no need to preheat or cool to ambient temperatures.

They also avoid the exposure of adjacent components to potentially stressful temperatures.

Our main business is in night-vision lighting systems, LED solutions, EMI filters and interconnect components. Robust, reliable and high in quality, we design our products with performance, specification and longevity in mind.

We are renowned for our innovative work in lighting and developed one of the earliest night-vision lighting systems when night-vision goggles (NVGs) were first adopted for use by the UK Ministry of Defence. The company has since become a world leader in the supply of night-vision lighting for military aircraft, vehicles, shelters and naval platforms.

With more than four decades' experience, Oxley is highly regarded in the development of LED solutions to replace traditional incandescent and fluorescent lighting. From miniature LED components to integrated lighting systems, Oxley is the supplier of choice for both off-the-shelf and customised solutions.
