That matters for a right-angle SMT part where the cable strain pulls on the solder joints. ## Electrical Ratings and Material Choices Operating temperature spans -25°C to 85°C.","metaTitle":"SM03B-NSHSS-TB JST NSH 3-Pin 1mm Pitch SMT Header","metaDescription":"JST NSH series 3-position male header, 1.00 mm pitch, SMT right-angle, latch holder, solder retention. 1 A, 50 V.
