Industry Snapshot
Key metrics for the electronic coil, transformer, and other inductor manufacturing industry.
Industry Definition & Overview
Capacitor, Resistor, Coil, Transformer, and Other Inductor Manufacturing (NAICS 334416) encompasses establishments primarily engaged in manufacturing electronic capacitors, resistors, and inductors used across virtually all electronic devices and systems. Fixed and variable capacitors, condensers, resistor networks, thermistors, varistors, coils, and small electronic transformers all fall under this classification. The U.S. Census Bureau[5] separates this code from electrical capacitor and transformer production classified under NAICS 335999 and 335311 respectively.
County Business Patterns data reports roughly 640 establishments operating in this industry across the United States, with total employment of approximately 17,400 workers according to Census data[6]. Production requires specialized clean room environments, precision winding equipment, and thin film deposition systems. Raw material inputs include ceramic powders, tantalum, aluminum foil, copper wire, and ferrite cores. Many domestic manufacturers focus on military specification and aerospace grade components where reliability testing adds substantial value.
Global trade volumes are considerable for this sector. U.S. imports reached $4.96 billion while exports totaled $4.58 billion, with China, Japan, and Mexico serving as the primary trading partners. Domestic producers compete by specializing in high-reliability, tight-tolerance components for defense, medical, and automotive applications rather than commodity passive components where Asian manufacturers hold cost advantages. Production lead times for military specification parts often exceed six months due to extensive qualification testing requirements.

Key Insight: The SBA[8] sets the size standard for NAICS 334416 at 500 employees, classifying it within the Semiconductor and Other Electronic Component Manufacturing subsector. Firms below this threshold qualify for small business set-aside contracts and SBA-backed lending programs. Federal procurement in this space includes military specification capacitors, resistors for defense electronics, and specialized inductors for government communication systems. The SBA's contracting programs[9] provide pathways for qualified small manufacturers to access Department of Defense and NASA supply chains. Eligible businesses can access SBA 7(a) loans[10] for working capital, equipment, and acquisition financing, while 504 loans[11] support major fixed-asset purchases including real estate and heavy machinery.

Frequently Asked Questions
Common questions about this industry.
What types of businesses are classified under NAICS 334416?
Businesses manufacturing electronic passive components fall under this code. This includes producers of fixed and variable capacitors, condensers, resistor networks, thermistors, varistors, electronic coils, and small transformers. Companies making surface mount components, through-hole capacitors, and toroidal inductors all classify here according to Census Bureau definitions[5].
How is NAICS 334416 structured by establishment size?
The industry includes roughly 640 establishments nationwide per County Business Patterns[12] data. Most firms employ fewer than 100 workers, though several large multinational manufacturers maintain domestic facilities. Production is concentrated among specialty manufacturers serving defense, automotive, and medical markets where domestic sourcing requirements apply.
What is the SBA size standard for capacitor and resistor manufacturing?
The SBA[8] sets the size standard at 500 employees for NAICS 334416. Businesses with fewer than 500 average employees over the prior 24 months qualify as small businesses for federal contracting preferences and SBA loan programs.
What NAICS codes are related to capacitor and inductor manufacturing?
Closely related codes include 334413 (Semiconductor Manufacturing), 334418 (Printed Circuit Assembly), 334419 (Other Electronic Component Manufacturing), 335311 (Power Transformer Manufacturing), and 335999 (Miscellaneous Electrical Equipment). The key distinction is that 334416 covers electronic passive components while 335311 and 335999 cover electrical power components.
What industries rely on capacitor and resistor manufacturers?
