9774040960R is a surface-mount round spacer manufactured by Würth Elektronik as part of the WA-SMST series. This steel spacer with a tin-plated surface is designed to create precise spacing between PCBs or between a PCB and housing. The component has an overall length of 4.00mm, an outer diameter of 6.00mm, and an inner diameter of 4.20mm, with a through hole diameter of 3.30mm for mounting.
The spacer is rated for operating temperatures from -55°C to +150°C and is supplied in tape and reel packaging for automated SMT assembly. The datasheet specifies a solder cream thickness of 150 µm and a moisture sensitivity level of 1 (unlimited floor life). The part is RoHS compliant (2011/65/EU and 2015/863), REACH conform, and halogen free per IEC 61249-2-21 and JEDEC JS709B.
In PCB design, this spacer is suitable for board-to-board and board-to-housing spacing applications. The through-hole construction provides strong holding forces and torques, while the instant-removable polyimide tape used in tape and reel packaging assists reliable pick-and-place operation. When placing multiple spacers, designers should account for the polyimide tape flap to avoid interference.
The WA-SMST family is intended for spacing distances from 1 mm to 16 mm, and this 4mm variant is a common choice for general electronic assemblies requiring a low-profile, surface-mountable standoff.
