B3U-1100P
Overview
The B3U-1100P is an ultra-small, surface-mount tactile switch designed by Omron for space-constrained applications. Measuring just 3.00mm by 2.50mm with a low profile of 1.2mm, this SPST-NO switch includes a dedicated grounding pin to provide electrostatic discharge (ESD) protection. It features a top-actuated mechanism with a crisp tactile response and an operating force of 153gf.
Why Choose This Part
The B3U-1100P offers one of the smallest footprints in its class while maintaining a reliable dust-proof construction. The addition of a grounding terminal simplifies PCB layouts for ESD protection, and the 153gf operating force ensures a positive tactile click despite its diminutive size.

Key Specifications
Getting Started
When designing for the B3U-1100P, ensure your SMD land pattern accounts for the third grounding terminal to maximize ESD effectiveness. Follow the recommended reflow soldering profile carefully, as the ultra-small package has low thermal mass and is sensitive to excessive heat cycles.
