SMA connector PCB mount

SMA Coaxial Connector
This series of SMA coaxial connectors is designed for a wide range of wireless communication and high-frequency applications, including environments where waterproof performance is required. Supporting both standard and reverse polarity (RP) formats, these connectors offer excellent electrical performance, durability, and are ideal for PCB mount (through-hole) installations.

Mechanical Features:
Polarity Options: Standard / Reverse Polarity (RP-SMA)

Mounting Style: PCB mount, through-hole type

Materials:
Housing: Brass with gold plating

Contact Pin: Gold-plated brass (enhances conductivity and corrosion resistance)

Insulator: High-performance PTFE (Teflon) with excellent dielectric stability

⚡ Electrical Performance:
Frequency Range: 0 ~ 18 GHz

VSWR: Max. 1.3

Impedance: 50 Ω

Insulation Resistance: ≥ 5 GΩ

Dielectric Withstanding Voltage: ≥ 1000 V RMS

Contact Resistance:
・Center Contact: ≤ 3 mΩ
・Outer Contact: ≤ 2 mΩ

Operating Temperature: -65°C to +165°C

These connectors are widely used in RF modules, wireless communication devices, antenna interfaces, testing equipment, and IoT systems. Custom versions—such as vertical/horizontal configurations, SMT/THT mounting, varied dimensions, or waterproof designs—are available upon request.
