Rutronik offers the DURIS E2835 from ams OSRAM

The products made of pre-moulded PPA with the standardized 2835 footprint (2.8 mm x 3.5 mm) combine good mechanical flexibility and a wide beam angle of 120° (Lambertian emitter) with the compact form factor and offer competitive value at both application and system level. The cost-effective components are available with different CRIs (Colour Rendering Indices), from 2,200 K to 6,500 K, ensuring good control of colour consistency. Their impressive mechanical strength and adaptability when mounted on flexible substrates make them the ideal light source for professional interior lighting, strip lighting or round ceiling luminaires. The DURIS E 2835 is a DLC premium product with an excellent service life.

The LEDs are installed in white SMT housings. Their ESD (electrostatic discharge) is a low 2 kV according to ANSI/ESDA/JEDEC JS-001 (HBM, class 2). Test results according to IESNA LM-80 for lumen maintenance are already available.

The DURIS E 2835 has a comprehensive reliability assessment prior to product release and covers three CRIs (GW JTLMS3.EM: CRI 80; GW JTLMS3.CM: CRI 90; GW JTLMS3.GM: CRI 97) to meet the diverse requirements of interior lighting designs. High CRIs, such as the GW JTLMS3.GM with a CRI of 97, are predestined for niche applications with high demands on the quality of colour rendering. The specially matched colour temperature (CCT) of 2400 K is particularly suitable for waterproof consumer applications. They deliver optimum results at an operating temperature range of -40 °C to +100 °C.
