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_65822 ( "Part Number" text, "Pins" text, "Body Width/mm" real, "Body Length/mm" real, "Lead Pitch/mm" real )

### Question ###
Which Lead Pitch/mm has a Part Number of tsop40, and a Body Length/mm larger than 18.4?

### Accurate SQL ###

SELECT MAX("Lead Pitch/mm") FROM table_65822 WHERE "Part Number" = 'tsop40' AND "Body Length/mm" > '18.4'
