FAQ
Sample Delivery Time
Regular models require 15 days, while some complex connectors require 25 days.
Sample Fee
Most RF connectors are CNC-machined parts and do not require mold-making.
However, each part needs to be fine-tuned on the CNC machine. Typically, a single sample costs $200.
This fee will be refunded after a 5K bulk order.
Guarantee
Brass RF connectors come with a one-year warranty.
Stainless steel connectors come with a three-year warranty.
The lifespan also depends on the contact material—beryllium contacts offer better durability.
ROHS & REACH Compliance
Our products fully comply with ROHS & REACH regulations.

Materials
Common materials include:
Body: Brass, stainless steel
Insulator: PTFE, PEEK
Contacts: Brass, phosphor bronze, beryllium copper
Other: Aluminum, titanium alloy
What is impedance, and why is 50 Ω or 75 Ω important?
Impedance matching prevents signal reflection and power loss. 50 Ω: Standard for RF communication, test equipment, aerospace, defense. 75 Ω: Standard for broadcast, video, and cable TV applications.
What materials are RF connectors made of?
Body: Brass, stainless steel, or beryllium copper (with nickel, gold, or silver plating). Insulator: PTFE, PE, or advanced low-loss dielectrics. Contacts: Gold-plated brass or beryllium copper for low resistance and durability.
