Through-hole solder termination on both the center pin and shield keeps the launch solid for board-edge or panel-mount RF paths. ## Key RF and Environmental Specs Rated insertion loss is 0.3 dB across the band — low enough for receiver front-end or antenna feed paths where every tenth of a dB matters. Voltage rating is 335 V.","metaTitle":"TE 221789-1 SMA Jack, 50 Ohm, 4 GHz, Through Hole, Obsolete","metaDescription":"TE 221789-1 SMA jack, 50 Ohm, 4 GHz max, through-hole solder termination, gold body.
