634108185421 Description

Short technical summary and product information.

The Würth Elektronik 634108185421 is a shielded surface-mount modular jack from the WR-MJ series, designed for 8P8C (RJ45) Ethernet applications. It features a right-angle (90°) orientation with a tab-down configuration, making it suitable for compact PCB layouts where space is constrained.

 

This connector is built with a copper alloy contact material and selective gold plating, ensuring reliable signal integrity over repeated mating cycles. The insulator is molded from PA9T material in black, with a UL94 V-0 flammability rating for safety compliance. The shield is made of brass with nickel plating, providing effective EMI protection.

 

Electrical ratings include a current capacity of 1.5 A per contact and a working voltage of 125 VAC. The connector can withstand 1000 VAC pin-to-pin and 1500 VAC from shield to pin for one minute. Contact resistance is a maximum of 35 mΩ, and insulation resistance is a minimum of 1000 MΩ. The operating temperature range is -40°C to +85°C.
