Frequently Asked Questions
What is the body depth of the TMM-104-03-T-D and why does it matter for stacked PCB designs?
The TMM-104-03-T-D has a body depth of 0.059 inch (approximately 1.5 mm), making it one of the lowest-profile vertical headers in its class. This compact depth is critical for stacked PCB assemblies where total board-to-board clearance may be limited to 5 mm or less, allowing designers to maximize component density.
Which contact finish does the TMM-104-03-T-D use and how does it affect mating cycle life?
The TMM-104-03-T-D uses matte tin over nickel (50 microinch nickel barrier) on both mating and termination surfaces. This finish supports a minimum of 30 mating cycles under standard conditions and provides adequate corrosion resistance for indoor industrial environments at temperatures up to 85°C.
How quickly can the TMM-104-03-T-D be sourced and what is the typical lead time?
SAMTEC lists the TMM-104-03-T-D with a factory lead time of 1 week, and the part is stocked by major distributors worldwide. For volume orders, the 4-position dual-row configuration ships in tape-and-reel or bulk packaging with standard minimum order quantities of 100 pieces per order.
