691321300020 Description

Short technical summary and product information.

The Würth Elektronik 691321300020 is a WR-TBL Series 321 vertical PCB header designed for reliable wire-to-board connections in terminal block applications. This shrouded header features 20 male pins arranged in a single level with a 3.81mm pitch, making it suitable for compact PCB layouts.

 

Electrical ratings include a current rating of 10A (cULus) and 10.5A (VDE) with a working voltage of 300VAC. The contact resistance is a maximum of 20 mOhm, and withstanding voltage is 1.6KV (cULus) / 2.5KV (VDE). The operating temperature range is -40°C to 105°C.

 

The insulator is made of green PA66 with a UL94-V0 flammability rating. Contact pins are brass with tin plating, and the solder tails are also tin-plated for compatibility with JEDEC lead-free wave soldering processes. Packaging is in boxes.
