This document is a datasheet for 3M company's 070-inch DIP socket. The socket has the characteristics of glass filled polysulfone insulation material, UL 94V-0 flammability, green marking, beryllium copper contact material, gold flash nickel plating, 1 amp current rating, 1000 Vrms rated voltage, -55°C to +150°C environmental working temperature range, and 20000 actuation life.
The .070" DIP sockets are shrink‑type ZIF sockets designed for DIPs with .070" (1.78 mm) lead spacing and pin counts from 28 through 90 leads. They feature a lever‑actuated zero insertion force mechanism and a socket contact point .090" (2.29 mm) below the top surface.
The leaflet lists key specifications such as a 1 A current rating, >1 × 10⁹ Ω insulation resistance at 500 Vdc, and a 1000 Vrms withstanding voltage. Materials include glass‑filled polysulfone insulation and beryllium‑copper contacts with gold flash over nickel plating. Operating temperature ranges from –55 °C to +150 °C, and the socket is rated for about 20,000 actuations at room temperature. Ordering part numbers and dimensions for each pin count are also provided.
