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 ###

### Question ###
Which Body Width/mm has a Lead Pitch/mm smaller than 0.55, and a Part Number of tsop48?

SELECT MIN(body_width_mm) FROM table_name_63 WHERE lead_pitch_mm < 0.55 AND part_number = "tsop48"
