Import 5mm Round Red Led Diodes — Buy in Bulk from Supplier in China

These 5mm round red LED diodes are through-hole components with a 5mm diameter and red diffused lens for uniform light distribution. The source specifies long feet type for simplified soldering and installation onto PCBs or panel mounts. Operating voltage is low, which reduces power consumption in continuous-use applications. The red diffused lens scatters emitted light to reduce glare and provide consistent appearance across viewing angles, a typical approach for indicator and signage applications where point-source brightness is undesirable.

The semiconductor die for red emission at this wavelength is typically aluminium gallium indium phosphide (AlGaInP) on gallium arsenide substrate, though you should confirm the exact epitaxy with the supplier. Standard 5mm round epoxy packages use a domed lens to optimise forward-direction intensity, with the diffused variant trading peak intensity for angular uniformity. The long lead configuration suits hand soldering and through-hole auto-insertion equipment. Typical forward voltage for red LEDs in this class ranges from 1.8 to 2.2V at 20mA test current, with dominant wavelength from 620 to 630nm for saturated red appearance. The source does not state exact electrical or optical specifications, so buyers should request a full datasheet before committing to volume purchase.

Applications span automotive indicator lamps, consumer electronics status lights, electronic signage, and decorative lighting arrays. The round 5mm form factor is a commodity package with broad second-source availability, making it suitable for designs where supply chain continuity matters. Hobbyist and maker markets consume this package in large volumes alongside industrial OEMs. The source mentions ISO and CE certifications for the product line, though the scope and validity of these should be verified against the specific diode model. No minimum order quantity, price, or lead time is stated in the source data. Buyers should confirm packaging format (typically taped on reel or bulk bag), lead finish composition (tin, tin-copper, or tin-silver for RoHS compliance compliance), and whether the diffused lens is internally or externally treated.

Shenzhen Bolin Electronic Co., Ltd is based in Banan District, Shenzhen, Guangdong Province 518053, China. Shenzhen is the primary cluster for LED component manufacturing and electronics assembly globally, with extensive supply chain infrastructure including component markets, testing laboratories, and shipping logistics through Shenzhen Port and Hong Kong International Airport. The supplier holds a harbor trust tier and imported supplier tier classification. Response rate and average response hours are both at zero in the source data, which means no response metrics are available rather than zero percent response.

The supplier name indicates electronic component specialisation, and the district location (Banan) places it within Shenzhen's broader industrial basin rather than the central tech corridor of Nanshan or Bao'an. No factory size, year of establishment, employee count, revenue, or client list is stated in the source. Buyers should verify whether Shenzhen Bolin Electronic Co., Ltd is a manufacturer with in-house epitaxy and packaging capability, or a trading company that sources finished LEDs from upstream fabs. The source description contains platform-generated content that should be disregarded in favour of direct supplier communication for accurate capability assessment.
