Description
SMA Termination Load Jack (Female) with Heatsink | DC to 18 GHz | 50 Ω | 25 W
The ROSNOL T-A25-18G25WA/9X is a high-power 50 Ω RF termination designed for DC to 18 GHz operation, supporting 25 W average power at 25 °C and up to 5 kW peak power (5 µs pulse width, 0.25% duty cycle). Mechanical integrity includes screw-lock coupling, ≥ 500 mating cycles, coupling test torque 1.70 Nm max, and recommended torque 0.9 Nm for secure and repeatable connections.Materials and Plating: centre contact—beryllium copper with gold plating (non-magnetic nickel–phosphorus underplating); body—stainless steel, passivated; insulator—PTFE; heatsink—black anodized aluminum. This termination is ideal for RF/microwave test systems, telecom infrastructure, and instrumentation requiring robust power handling and efficient thermal dissipation for extended high-power operation.
ROSNOL RF components are manufactured under ISO 9001-certified processes and fully comply with RoHS and REACH regulations. Combining high build quality with competitive pricing, ROSNOL products provide a reliable alternative to leading European and American brands, with full customization services for materials, plating, and mechanical design.
