Components Bureau's Precision Range Fulfils LED Driver Design Requirements

Components Bureau targets the LED lighting industry with its Precision range, which includes both high- and low-frequency transformers and inductors. The Precision range of products is designed to fulfil the lighting industry’s needs in terms of flexibility, quality and value, while meeting these short lead time requirements.

“Manufacturers of lighting solutions, such as LED lighting systems, require the appropriate converters for switching, protecting, and regulating. Therefore, considering the most common converter topology in LED markets, constant voltage or constant current power supplies, the components at the heart of the power converter systems need to be sourced easily and efficiently. Our specialisation is in wound components for SMPS (switch mode power supplies), LED drivers and electronic ballasts,” explains Ruggero Ravazzini, Precision range product manager at Components Bureau. “However, when you need a transformer or inductor urgently and lead times start from 6 weeks, it can cause major headaches. Increasingly long lead times are a common problem facing many at the moment.”

“We guarantee response times within 14 days from drawings to samples as standard and production volumes from as little as 3 weeks ex-factory,” adds Ravazzini.

Specific to LED driver designs, the Precision range includes PFC chokes, common mode chokes and switch mode transformers. In addition to wound component supply, Components Bureau offers supporting services in terms of materials sourcing, metalwork and some PCB assembly.

Both standard and fully-custom products are built at the company’s affiliated ISO9001:2008-certified plants in China and are fully designed and tested in accordance to International standards (UL (cURus) / CENELEC / IEC EN/ standards prior to dispatch. Custom marking and packaging options are available upon request.
