3505-2 Description

Short technical summary and product information.

The 3M Electronic Solutions 3505-2 is a Four-Wall Header belonging to the 3000 Series. This header is designed with a 0.100" x 0.100" pitch, making it suitable for various interconnect applications.

Key electrical specifications include a current rating of 2A (EIA 364-70) and an insulation resistance greater than 1 x 10⁹ Ω at 500 VDC. The header can withstand voltages of 1,000 VRMS at sea level. The operating temperature range is from -55°C to +105°C, with a process rating of 260°C for high-temperature soldering operations.

The insulator material is Glass Filled Polyester (PBT) or Glass Filled Polyester (PCT) for high-temperature options, with a flammability rating of UL 94V-0. The contacts are made of Copper Alloy, with Nickel underplating and 30 µ” Gold for the wiping area. Solder tails are available in Tin Lead or Matte Tin.

This header supports military and centerbump polarization, with optional ejector latches and mounting holes for board security. It is suitable for "no lead" soldering operations and reflow soldering using "paste in hole" techniques.
