Busbars are simple in principle, complicated in practice: part 2

1 week ago | connectortips.com | Bill Schweber

These substantial conductors serve a vital role and must meet many conflicting constraints. This part explores additional bus-bar considerations. Part 1 can be found here. While some busbars are single conductors and carry only one power rail, there’s an increasing trend towards using laminated busbars, seen in Figure 1. These multilayer units carry two, three, or more independent power rails in parallel.
Bus bars are simple in principle, complicated in practice: part 1

2 weeks ago | connectortips.com | Bill Schweber

Bus bars appear to be simple and low glamour in comparison to many other active and even passive components, and in some ways, they are. However, they are also sophisticated structures that require an understanding of voltage drop due to conductor resistance, materials science, thermal issues, mechanical joining, insulation, coating chemistry, and electrical safety and integrity tests.
USB-C connector conforms to automotive standards

2 weeks ago | connectortips.com | Redding Traiger

Hirose has launched a shielded USB Type-C connector that complies with USCAR-2 and USCAR-30 standards. The AU1 Series features a reinforced shell and housing that delivers superior vibration and heat resistance up to 105°C. Supporting USB 3.2 Gen2, DisplayPort 1.4, and HDMI transmission standards, the AU1 Series offers flexible connectivity across a range of in-vehicle systems.
What are the important standards for compliance with wire harness-to-PCB interfaces that engineers should know?

3 weeks ago | connectortips.com | Rakesh Kumar

When connecting cable assemblies to PCBs, you need more than just a physical connection. These interfaces must meet specific industry standards to deliver minimal performance across different applications. Understanding the right standards for your project is necessary when applying to both consumer electronics and aerospace systems. This FAQ discusses the most common standards for the wire harness-to-PCB interface. Q: What is the IPC/WHMA-A-620 standard, and how do its classes affect connections?
What are the different types of wearable military connectors?

1 month ago | connectortips.com | Aharon Etengoff

Many soldier-worn systems integrate advanced sensors and communications technologies into uniforms, helmets, and tactical vests. These technologies rely on rugged, lightweight connectors to link disparate systems, deliver power safely, and ensure reliable data transmission on the battlefield. This article explores the evolution of soldier-worn military technologies and the role of wearable connectors in enabling seamless coordination, real-time communications, and system interoperability.
SMD jumpers handle overload currents up to 158 A for power applicatio

1 month ago | connectortips.com | Redding Traiger

Electronic circuits use zero-ohm jumpers to simplify routing, manufacturability, testing, and enable various design options. Jumpers with higher current capability allow for a smaller jumper chip to be used, which can reduce the space needed for a design. Traditional thick film jumpers handle up to 3 amps, while high-current versions max out at 10 amps. Stackpole’s AEC-compliant HCJ series high-current SMD jumpers deliver up to 70.7 amps of continuous current and handle overloads up to 158 amps.
Automotive wire-to-board connector meets low-voltage standard

1 month ago | connectortips.com | Redding Traiger

Hirose has developed an automotive wire-to-board connector that meets the GMW3191 standard for low-voltage automotive applications and the ADM-F-0006 vibration test standard to ensure reliability and durability in harsh environments. Featuring a unique contact spring structure for vibration resistance and a rugged center lock that prevents mis-mating, the KM32A Series offers a tensile/pry strength of up to 75N. In addition, the KM32A Series provides heat resistance up to 125°C.
What is the role of interconnects in continuous glucose monitors (CGMs)?

1 month ago | connectortips.com | Aharon Etengoff

Continuous glucose monitors (CGMs) rely on precision electronic components — including specialized connectors and interconnects — to ensure accurate sensing, signal integrity, and reliable data transmission. This article reviews the core functionality of CGMs and highlights the key role of interconnects in these critical medical devices.
2 AWG twinax cable optimized for 224 Gbps PAM4 applications

1 month ago | connectortips.com | Emma Lutjen

A new twinaxial cable optimized for 224 Gbps PAM4 signaling has been released as part of an existing product family focused on high-speed data transmission. The product supports a 32 AWG conductor size for internal system cable assemblies. A 27 AWG version is under development to accommodate extended-reach cabled backplane use cases. In high-data-rate systems, skew between conductors in a differential pair becomes a limiting factor, particularly in 224 Gbps PAM4 signaling environments.
What type of interconnects and connectors link accelerator cards in AI data centers?

1 month ago | connectortips.com | Aharon Etengoff

Many data centers are packed with racks of high-performance graphics processing units (GPUs) and tensor processing units (TPUs). These accelerators process massive artificial intelligence (AI) and machine learning (ML) datasets, executing complex operations in parallel and exchanging data at high speed. This article explores the interconnects and connectors that link AI accelerator clusters together.
