TSM4 SMT Miniature Multi-Turn Trimmers Vishay/Sfernice TSM4 SMT Miniature Cermet Sealed Multi-Turn Trimmers are designed for surface mount applications and offer volumetric efficiency (5mm x 5mm x 3.7mm) with high performance and stability. The TSM4 design is suitable for both manual or automatic operation and can withstand vapor phase and reflow soldering techniques. The components are professional and industrial grade with a wide ohmic range (10Ω to 1MΩ). The TSM4 Trimmers feature 0.25W at 70°C, a low contact resistance variation of 2% or 3Ω, and are RoHS Compliant.
