Frequently Asked Questions

What is the current rating and contact material specification of the Winslow W30540SFTRC DIP40 socket?

The Winslow W30540SFTRC is rated for 3A continuous current with gold over nickel mating contacts (4 microinches gold over 98 microinches nickel) on beryllium copper springs. The pure tin termination with nickel barrier provides excellent long-term electrical stability and prevents contact corrosion in test fixtures operating at up to 125°C, making it suitable for 40-pin DIP through-hole device insertion across 100+ cycles without contact degradation.

For circuit board prototyping and IC burn-in testing, how does the 2.54mm DIP40 socket compare to soldered headers?

The Winslow W30540SFTRC socket eliminates permanent solder connections, enabling rapid IC swapping for 1000+ insertion-removal cycles on 2.54 mm 40-pin spacing without damaging component leads or board traces. Soldered headers require desoldering and cause cumulative pad wear, whereas this open-frame socket provides mechanical retention with 3A rating while keeping IC devices in reusable condition for multiple test and development phases in prototype and manufacturing environments.

What are the package dimensions and housing material of the W30540SFTRC IC socket?

The Winslow W30540SFTRC measures standard DIP40 footprint with 2.54 mm lead pitch and polybutylene terephthalate (PBT) polyester housing rated UL 94V-0 for flame retardant applications. The housing material provides dimensional stability from -40°C to 125°C operating range, UL safety certification for medical and aerospace systems, and pb-free RoHS compliance ensuring reliable socket performance across 10+ year production deployment cycles.

Is the Winslow W30540SFTRC suitable for aerospace and medical device manufacturing applications?

Yes, the Winslow W30540SFTRC features UL 94V-0 flame retardant polyester housing, gold over nickel contacts, and Pb-free construction making it ideal for aerospace, medical device, and industrial control system test fixtures. The beryllium copper spring contacts withstand thermal cycling from -40°C to 125°C with stable 3A current rating, supporting high-reliability burn-in procedures and qualification testing for AS9100 aerospace and ISO 13485 medical device manufacturing environments.
