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_65821 ( "Part Number" text, "Pins" text, "Body Width/mm" real, "Body Length/mm" real, "Lead Pitch/mm" real )

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

### Accurate SQL ###

SELECT MIN("Body Width/mm") FROM table_65821 WHERE "Lead Pitch/mm" < '0.55' AND "Part Number" = 'tsop48'
