Product Description

3mm Red Diffused LED Single Level Circuit Board Indicator

This circuit board indicator are acutally made by 3mm red through-hole LED inside and cover with a black case that can bent the LED pins as right angle. We finished the red LED lamps at first, and then we need to install this red LED(625nm LED) into the black plastic case. In this circuit board indicator, we produce this red through-hole LED inside as a red diffused lens, which can make this emitting light be more soft and easy to see directly. But if you don't want this red diffused lens, it's also available in clear lens, milky lens ect. On the other hand, this LED are also available in different colors, which is widely use in diagnostic, industrial equipement and data storage application. Less PC board space needed, height and spacing alignment saves assemnly cost. If you are interested in this 312URD-3.5HK right angle LED circuit board indicator, just feel free to contact us for more information~

This red through-hole LED are made with Gap material chip, which have high reliability, high radiant intensity;

With pure gole wilre, famous branded, high quality epoxy and high quality LED frame. This LED circuit board indicator will wor perfectly for your project!

Through-hole LED detail


1, A moisture barrier bag(MBB)containing LEDS shall be kept in an environment with temperature below40C and humidity below 90% RH. A MBB shall be kept sealed until the LEDS contained in that bag are to be used immediately.Storge in an environment with temperature 5-30 C and humidity below 60% RH

2. After a MBB has been opened, all LEDS contained in that bag shall complete soldering process withinaccording to the conditions listed on the Best LED MBB.

3. If the 10% spot of a Humidity Indicator Card (HIC)indicates wet, LEDS shall be baked according tothe conditions listed on the Best LED MBB.

4. During soldering, component covers and holders should leave clearance to avoid placing damagingstress on the LED during soldering.

Right Angle LED Circuit Board Indicator

5 . The tip of the soldering iron should never touch the lens epoxy

6 . After soldering , allow at least three minutes for the component to cool down to room temperature before further operations

7 . If the LED will undergo multiple soldering passes or face other processes where the part may be subjected to intense heat , please check with Best LED for compatibility

8 . Recommended Reflow Soldering Profiles For SMD Housing LEDS;

Single color right angle LEDs


1, We recommend the reflow temperature 245℃(±5℃). The maximum soldering temperature should be limited to 260℃.

2, Don't cause stress to the epoxy resin whilte it is expossed to high tempreature.

3, Recommended solder: Sn/Cu/Ag;

4, No more than once;
