From smartphones and electric vehicles to 5G infrastructure and aerospace systems, the demand for highly reliable and miniaturized electronic components is booming. At the core of this silent revolution lie interconnects and passive components—the unsung heroes that ensure signal integrity, power distribution, and overall circuit stability. The U.S. market for interconnects and passive components is experiencing steady growth as the country continues to invest in advanced electronics, digital transformation, and domestic semiconductor capabilities.
Market Overview
The U.S. Interconnects and Passive Components Market share was valued at approximately USD 33.5 billion in 2024 and is expected to reach around USD 52.7 billion by 2032, growing at a CAGR of 5.8% during the forecast period. This growth is underpinned by rapid developments in consumer electronics, EVs, 5G rollouts, industrial automation, and aerospace & defense systems.
Understanding the Components
● Interconnects: These include connectors, sockets, terminals, wire harnesses, PCB traces, and cables—used to electrically or mechanically join devices or systems.
● Passive Components: This category includes resistors, capacitors, inductors, transformers, filters, and RF components. They do not require a power supply to function and are vital for signal conditioning, energy storage, and electromagnetic shielding.
Key Market Drivers
1. Electrification of Transportation
The U.S. is investing heavily in electric vehicles (EVs) and EV charging infrastructure. EVs use significantly more passive components and connectors than traditional ICE vehicles due to their reliance on advanced electronics, battery management systems, and power conversion modules.
2. 5G and Telecommunications Expansion
Deployment of 5G infrastructure requires high-frequency components, precision connectors, and RF passive devices to handle increased bandwidth and signal fidelity. U.S. telecom operators are fueling demand across urban and rural networks.
3. Semiconductor Reshoring Initiatives
Under the CHIPS Act, the U.S. is reshoring semiconductor production. This is boosting demand for high-performance passives and interconnects used in chip packaging, testing, and supporting PCB infrastructure.
4. Aerospace and Defense Systems
Mission-critical defense applications require radiation-hardened, high-temperature tolerant, and military-grade passive components. The U.S. Department of Defense’s emphasis on secure supply chains supports domestic manufacturers of interconnects and passives.
5. Industrial Automation and IIoT
Factory modernization and the growth of Industry 4.0 technologies, such as predictive maintenance and robotics, are fueling demand for robust, long-life passive components and shielded, EMI-resistant interconnects.
Technology Trends
Miniaturization and High-Density Packaging: To fit into increasingly compact electronic devices, components are being reduced in size while maintaining or improving performance.
High-Reliability Components: Aerospace, defense, and medical applications require AEC-Q200, MIL-STD, and automotive-grade certified components for harsh environments.
Embedded Passive Technology: Passives embedded directly into PCBs are gaining traction to improve performance and save board space.
Smart Connectors and Modular Interconnects: These offer plug-and-play functionality, diagnostics, and are ideal for next-gen edge computing and AI applications.
