The single contact keeps the footprint small: one pad for the signal, one for the ground or a dedicated return path, depending on the layout. The LCP housing holds up to reflow soldering without warping. ## Temperature Range and Environment Fit The LCP housing retains its mechanical properties across that span, so the contact beam doesn't relax at high temperature or get brittle in cold. If the assembly sees thermal cycling, the gold plating prevents fretting corrosion at the contact interface — a common failure in tin-plated signal connectors under vibration.","metaTitle":"JST 01R-LELSS-GA-TF(HF) LEL Series 1-Position Receptacle","metaDescription":"JST LEL series 1-position board-to-board receptacle, SMT right-angle, gold contacts, rated 1.6A at 100V.
