3mm red diffused led with High brightness and quality, RoHs Standard;
This 304URD looks like the same as 304NRD, They are all with the same size, red diffused lens and they even got similar brightness when you light them up. Then what's the different between these Red Through-Hole LED?
First, for the cost, 304URD will got higher unit price than 304NRD.
For the warranty, 304URD got 5 years warranty. But for 304NRD, it's only got one years. And on the other hand, 304URD will got much better performance than 304NRD on the lighting.
In addition, if you need this 3mm 625nm LED to meet the RoHs standard in your project, 304URD will be better for your applications. We use the pure gold wire inside for connect and high quality epoxy, all this material will meet the high quality standard.
So, what's your choice, 304URD or 304NRD?

Product Details:
99.99% purity gold wire;
Silver plated LED frame;
Famous branded chips;
High quality epoxy;
Manufacturing progress of through-hole LED:
Compare with SMD LED, through-hole LED production will be more complicated. Which means it will take more production progress and production time:
First of all, we need to prepare the LED chip(this will be same as SMD LED production); Secondly, we will need to put the LED chip into the LED frame, and then we will need the pure gold wire to connect the cathode and anode of LED frame. There comes different, For SMD LED production, we need to put the epoxy to LED frame and wait until it dry by oven. However, for LED Lamps, we need to inject epoxy into the mold of lens and put all the things to oven for at least 8 hours until they dry. After that, we need to tae them from the oven and get the LED out of mold. And then we need to cut the pins of LED so that they can be easy to test.
Finally, we got the LED. In order to make sure the quality and the uniform as good as required. We also need to put all the LED to the separation machine and them we will got the LED with same bins.
Storage Conditions:
1. avoid continued exposure to the condensing moisture environment and keep the product away from rapid transitions in ambient temperature;
2. LEDs should be stored with temperature ≤30℃ and relative humidity<60%℃;
3. Product in the original sealed package is recommended to be assembled within 72 hours of opening;
4. Product in opened package for more than a week should be baked for 6-8 hours at 85-10℃;
LED MOUNTING METHOD
1, The lead pitch of the LED must match the pitch of the mounting holes on the PCB during component placement;
Lead-forming may be required to insure the lead pitch matches the hole pitch;
Refer to the figure below for proper lead forming procedures;
Do not route PCB trace in the contact area between the leadframe and the PCB to prevent short-circuits;
Noted:
○ Correct mounting method;
× Incorrect mounting method;
2. When soldering wires to the LED, each wire joint should be separately insulated with heat-shrink tube to prevent short-circuit contact.
Do not bundle both wires in one heat shrink tube to avoid pinching the LED leads;
Pinching stress on the led leads may damage the internal structures and cause failure;
Noted:
○ Correct mounting method;
× Incorrect mounting method;
3. Use stand-offs(Fig 3)or spacers(Fig 4)to securely position the LED above the PCB;
4. Maintain a minimum of 3mm clearance between the base of the LED lens and the first lead bend (Fig. 5. Fig. 6)
5. During lead forming, use tools or jigs to hold the leads securely so that the bending force will not be transmitted to the LED lens and its internal structures;
Do not perform lead forming once the component has been mounted onto the PCB;
Lead Forming Procedures
1. Lead Forming Procedures;
2. Do not bend the leads more than twice (Fig. 7);
3. During soldering, component covers and holders should leave clearance to avoid placing damaging stress on the LED during soldering(Fig 8);
4. The tip of the soldering iron should never touch the lens epoxy;
5. Through-hole LEDs are incompatible with reflow soldering;
6. 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;
