The SMA female 4-hole flange mount RF connector<\/strong> with 1.23 mm pin and 8.65 mm hole spacing is engineered for solder attachment<\/strong> in high-frequency assemblies requiring excellent repeatability and robust mechanical support. Designed for 50 \u03a9 impedance<\/strong> operation from DC to 18 GHz, the SMA-KSS3 connector ensures high signal integrity and low reflection across broadband applications.<\/p>\n With VSWR \u2264 1.08<\/strong> and insertion loss \u2264 0.06 \u221aF(GHz) dB<\/strong>, the SMA-KSS3 RF connector<\/strong> provides efficient power transmission and minimal signal degradation. Its precision-machined 1.23 mm center pin guarantees stable mating and excellent contact reliability, even under repeated connection cycles.<\/p>\n Manufactured from passivated stainless steel with gold-plated beryllium copper contacts, the SMA-KSS3 connector<\/strong> offers exceptional corrosion resistance, electrical conductivity, and long-term durability. All materials conform to RoHS and REACH<\/strong> environmental compliance standards.<\/p>\n The 4-hole flange mount configuration<\/a> ensures precise alignment and firm attachment in RF enclosures, filters, and amplifiers. Its solder interface simplifies assembly, providing reliable strain relief for applications exposed to vibration or temperature variation.<\/p>\n Mechanc offers an extensive line of SMA connectors<\/a> for laboratory, aerospace, and communication systems.
