Fairview Microwave 3.5mm SM33x Adapters offer gold-over-nickel-plated beryllium-copper contacts, passivated stainless steel bodies, 50Ω impedance, 500 mating cycles, and a DC to 34GHz range. The SM3310 series is a straight in‑line adapter with ≤1.25 VSWR, ideal as a general‑purpose connector saver, while the SM3312 adds bulkhead mounting in the same form factor and VSWR, making it ideal for panel or enclosure feed‑throughs. The SM3313 utilizes a four-hole flange mount, accepts clearance-through panel configurations, with a slightly higher ≤1.3 VSWR, suited for rack-mounted and chassis applications. SM3315 and SM3320 adapters offer male-to-male and male-to-female configurations, ensuring the ideal fit is available for any project. Fairview Microwave 3.5mm SM33x Adapters are suitable for general-purpose test equipment.
