It carries a 50 Ohm characteristic impedance and is rated to 18 GHz maximum frequency, making it suitable for microwave signal chains up to the Ku band. The stainless steel body with silver finish provides corrosion resistance, while the PTFE dielectric ensures low loss and stable phase performance across the operating band. The center contact is beryllium copper with gold plating — a combination that delivers high mating cycle durability (500 cycles rated) and low contact resistance for consistent RF performance over repeated connects. The threaded fastening (SMA standard) provides vibration-resistant coupling, and the flange mount allows secure bulkhead installation. The extended insulation feature adds creepage distance, supporting the 335 V voltage rating in contaminated or high-altitude environments.
Comparison with 415420-1
Both are SMA receptacles in Bulk packaging with Active lifecycle status. The 415420-1 shares the same 50 Ohm impedance and panel-mount form factor, making it a direct cross-shop candidate for BOM positions where the 1052902-1 is specified. Verify the specific flange dimensions and solder tail length against your board layout before substituting.
Compliance and Environmental
The stainless steel body and gold-plated center contact resist corrosion in humid or salt-fog environments. The PTFE dielectric is rated for continuous use at these extremes without dielectric breakdown.
