Murata Launches World’s Smallest RF / Microwave Coaxial Connectors with a Switch, Cutting PCB Mounting Area by Approximately 40%

What happened

According to a product news release from Murata Manufacturing Co., Ltd. dated 10/29/2026, the company has begun mass production of the SWL series MM8330-2600RJ5 and MM8330-2600RK20, the world's smallest RF/microwave coaxial connectors with a switch (based on Murata research as of October 28, 2026). Measuring 1.0 mm × 1.0 mm × 0.55 mm, the connectors reduce PCB mounting area by approximately 40% compared with Murata's previous SWJ series (1.4 mm × 1.2 mm × 0.65 mm); when used with dedicated probes, the PCB footprint including the keep-out area is reduced by approximately 60% versus the SWJ series. The SWL series supports DC to 15 GHz with a nominal impedance of 50 Ω; the MM8330-2600RJ5 is supplied on reels of 5,000 pieces and the MM8330-2600RK20 on reels of 20,000 pieces. The dedicated probes are scheduled to enter mass production in December 2026.
