940-99-052-24-000000 Description

Short technical summary and product information.

The Mill-Max 940-99-052-24-000000 is a standard PLCC socket from the Series 940 family, designed for through-board mounting. It accepts JEDEC PLCC packages conforming to MS-016 and MS-018 leaded plastic substrates. The socket provides 52 positions arranged in a 4 x 13 grid with a 2.54mm (0.100") pitch.

 

The insulator is made of glass reinforced PPS, and the contacts are beryllium copper plated with 150µ" tin/lead. The closed frame design includes standoffs that provide clearance for heat dissipation and cleaning, while internal standoffs ensure proper positioning of the chip carrier. The socket operates over a temperature range of -55°C to 125°C.

 

This socket is intended for through-hole soldering, with a PCB layout requiring 0.035" diameter holes and 0.062" diameter solder pads. The body dimensions are 1.013" length, 0.600" width, and 0.800" height, with a standoff height of 0.130". Contact resistance is rated at 23 mΩ.

 

The Series 940 sockets are not end stackable. Pre-lubricated versions are available for applications requiring enhanced reliability against fretting corrosion, particularly for long-life tin-tin interfaces.
