CREATE TABLE table_name_48 (body_width_mm INTEGER, lead_pitch_mm VARCHAR(255), body_length_mm VARCHAR(255))
Which Body Width/mm has a Lead Pitch/mm smaller than 0.55, and a Body Length/mm larger than 18.4?
    
SQL: SELECT MIN(body_width_mm) FROM table_name_48 WHERE lead_pitch_mm < 0.55 AND body_length_mm > 18.4
