Mill-Max 107306518 High-Current Pin Receptacles

Introduction

The Mill-Max 107306518 is a high-current pin receptacle designed to create reliable, removable electrical connections in demanding electronic and power applications. Its robust contact design supports substantial current flow while maintaining low contact resistance and dependable mechanical performance.

Part Description

Mill-Max High-Current Pin Receptacles use beryllium copper contacts within brass alloy shells to provide strong spring contact force, conductivity, and mechanical durability. They are available in open-bottom and closed-bottom configurations, allowing designers to select the arrangement that best suits their assembly and circuit-board requirements.

Key characteristics include:

• Up to 42 A current capacity with a 30°C temperature rise
• Maximum contact resistance of 10 mΩ
• At least 1,000 mechanical mating cycles
• Operating temperature range of -55°C to +125°C
• Solder-mount and press-fit installation options
• Designed for installation into non-plated through holes
• RoHS-compliant construction

These receptacles are suited for accepting mating pins in applications where conventional low-current headers or socket contacts may not provide sufficient current-handling capability.

Applications

Potential applications for high-current pin receptacles include:

• Power distribution boards
• High-current PCB interconnects
• Removable power modules
• Battery connection systems
• Motor-control electronics
• DC power supplies and converters
