Wurth Elektronik WA-SMSR Series SMT Reverse Steel PCB Spacer with M3 Thread 9775086360R

Wurth Elektronik 9775086360R SMT Reverse Steel PCB Spacer is engineered from high-quality tin-plated steel, featuring an M3 thread suitable for precise PCB spacing applications. This spacer is designed to be soldered on the top surface of the PCB, effectively creating a defined gap underneath, which is essential for ensuring proper mechanical clearance and isolation in sensitive electronic assemblies.

Manufactured according to industry standards such as DIN EN 61760-2 for storage and IEC 60286-3:2013 for packaging, this component also fulfills requirements under IPC/JEDEC J-STD-020E and JEDEC JS709B for soldering reliability. Being halogen-free and compliant with RoHS and REACH directives guarantees minimal environmental impact and safe usage in contemporary electronic manufacturing processes.

The WA-SMSR series SMT reverse spacers offer compatibility with automated assembly lines due to their robust mechanical design, high tightening torque capacity, and resilience under operational stresses. With a recommended use on PCBs of standard 1.6 mm thickness, these spacers allow adjustable distances ranging effectively between 1 mm and 10 mm, accommodating diverse layout needs.

Typical applications include PCB prototyping, cleanroom electronic assembly, ESD-sensitive component protection, and industrial manufacturing environments requiring mechanical support and spacing. The steel construction ensures long-term durability and mechanical integrity in demanding operational conditions.
