Physical Characteristics
- Nominal OD (Outer Diameter): 1.95 mm (0.077 inches) — Extremely small.
- Bending Radius: 10 mm (0.4 inches) static; 20 mm (0.8 inches) dynamic.
- Flexibility: Exceptionally flexible due to its tiny profile, allowing routing through the tightest gaps inside devices.
Common Connector Types
- SMA (SubMiniature version A): Most common for wireless modules and GPS antennas.
- MCX / MMCX: Very small push-on connectors often used in cellular modems and GPS receivers.
- U.FL (IPEX): Ultra-miniature surface-mount connectors found on Wi-Fi and Bluetooth PCBs.
- SSMB: A microminiature connector used in some military and aerospace applications.
Key Features
- Ultra-Small Profile: One of the smallest standard 50-ohm cables available, making it ideal for internal wiring in compact devices.
- High-Temperature Resistance: The FEP jacket allows the cable to withstand extreme heat (up to 200°C) without melting or degrading, unlike PVC.
- Chemical Resistance: FEP is highly resistant to solvents, oils, and most chemicals, making it suitable for harsh industrial or aerospace environments.
- High-Frequency Performance: Utilizes PTFE dielectric, which has low loss at high frequencies (up to 18 GHz), making it suitable for GPS and microwave signals.
Applications
- GPS Antennas: Commonly used as the pigtail cable connecting the GPS patch antenna to the receiver module inside a device.
- Internal RF Interconnects: Used inside laptops, routers, and handheld radios to connect the main board to antennas.
- Test & Measurement: Used as "probes" or short jumpers inside high-frequency test equipment.
- Aerospace & Defense: Utilized in avionics and military radios where weight, size, and temperature resistance are critical.
