Brass standoffs are essential components in electronic projects, particularly in applications where circuit boards need to be securely mounted within an enclosure or chassis.
Here's how they are typically used:
Board Mounting: Brass standoffs are used to elevate and secure printed circuit boards (PCBs) within an electronic enclosure or chassis. They provide a stable platform for the PCB, preventing it from coming into contact with conductive surfaces that could cause short circuits.
Mechanical Support: Standoffs act as spacers between the PCB and the mounting surface, ensuring proper ventilation and preventing heat buildup. This is crucial for maintaining the integrity of sensitive electronic components.
Isolation: Brass standoffs help to electrically isolate the PCB from the chassis or enclosure. This isolation is essential for preventing electrical interference, reducing the risk of noise and signal degradation, and enhancing overall circuit performance.
Easy Access: Standoffs facilitate easy access to the PCB for maintenance, repairs, or upgrades. By raising the board above the mounting surface, technicians can easily reach components and make necessary adjustments without disassembling the entire system.
Vibration Dampening: In applications where vibration is a concern, brass standoffs can help dampen vibrations transmitted to the PCB, thereby reducing the risk of component failure or solder joint fatigue over time.
Grounding: Depending on the design, brass standoffs can also be used as grounding points for the PCB. By connecting the standoffs to the ground plane on the PCB, they provide a convenient and reliable grounding solution.
Overall, brass standoffs play a crucial role in ensuring the structural integrity, electrical isolation, and proper functioning of electronic systems. Their versatility and reliability make them indispensable components in a wide range of electronic projects.

Q&A
1. Does the LED flexible filament need a heatsink?
The LED filament does not need a heatsink. The LED uses a current of ≤10mA, and does not require heat dissipation.
2. Can the LED flexible filament be powered with an 18650 battery (DC3.7V)?
No, the LED filament voltage is standard DC3V.
If you use DC3.7V, the voltage is too high and the filament temperature will be very high, which will burn out the lamp beads.
3. Where is the LED flexible filament used?
Generally used in light bulbs, DIY hand-made toys, DIY decoration designs and home projects.
4. Can the flexible LED filament bend 90 degrees?
No. Maximum bending angle of LED filament≥30°
5. Can the flexible LED filament be freely cut to length?
No. If it is cut, it will not light up.
6. Can the length of the LED flexible filament be customized according to customer requirements?
No. The length is fixed.
7. Can LED flexible filament work in water?
No. But you can DIY by yourself and put the LED filament in a sealed transparent plastic tube to make it work in water.
8. What is the CRI of the LED flexible filament?
CRI≥80
9.What is the maximum current of the 130mm and 300mm LED flexible filaments?
130mm and 300mm maximum current must be ≤100mA
10. How do I light up the LED flexible filament?
Connect two AA batteries in series = 3V to light up the filament. Or use a 3V button battery CR2032. You will find what you need in our battery and enclosure collections.
