SMA Female Solder Attachment Bulkhead RF Connector – Solder Cup, 1.27mm Pin Diameter

SMA Female Solder Attachment Bulkhead RF Connector – Solder Cup, Model SMA-KFD100-A

The SMA female bulkhead RF connector with a 1.27 mm pin diameter and solder cup termination is engineered for panel-mounted RF applications requiring high reliability and low insertion loss. Designed for operation from DC to 18 GHz at a 50 Ω impedance, this connector ensures secure performance in test equipment, RF enclosures, and signal transmission modules.

Electrical Performance and Stability

Delivering VSWR ≤ 1.08 and insertion loss ≤ 0.06 √F(GHz) dB, the SMA-KFD100-A bulkhead connector offers excellent impedance matching and consistent performance under wideband conditions. Its precision-machined 1.27 mm center pin maintains stable electrical contact, even under mechanical stress or repeated mating cycles.

Material Quality and Construction

Manufactured from high-grade stainless steel with gold-plated beryllium copper inner conductors, the SMA female solder cup connector provides long-term durability and optimal signal integrity. Fully REACH and RoHS compliant, it guarantees both environmental safety and extended operational lifespan.

Mounting and Application Versatility

The bulkhead mount design enables easy integration through RF panels or housings while maintaining strong mechanical support. The solder cup termination simplifies cable-to-connector attachment, making it ideal for laboratory instrumentation, communication modules, and RF chassis systems.
