Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_name_48 (body_width_mm INTEGER, lead_pitch_mm VARCHAR, body_length_mm VARCHAR)

### Question ###
Which Body Width/mm has a Lead Pitch/mm smaller than 0.55, and a Body Length/mm larger than 18.4?

### Accurate SQL ###

SELECT MIN(body_width_mm) FROM table_name_48 WHERE lead_pitch_mm < 0.55 AND body_length_mm > 18.4
