ECI designs and manufactures precision RF inductors engineered for demanding signal-chain and high-frequency applications. Our RF inductors support impedance matching, resonant and tuned circuits, RFI/EMI suppression, and filter choke designs across aerospace, defense, communications, data processing, and instrumentation systems.
We offer a broad range of wire-wound RF inductor configurations, including axial and radial leaded, toroidal, air-core, and surface-mount (SMT) designs. Custom constructions are available using semi-rigid or flexible coaxial cable to meet specialized electrical and mechanical requirements. Additional RF solutions include tuned notch filters and directional couplers for advanced signal control and filtering architectures.
Axial Leaded Precision RF Inductors (RFA1-XXX Series)
ECI’s RFA1-XXX family of axial leaded RF inductors is precision-tuned to an inductance tolerance of ±1%, making them ideal for tightly controlled resonant and frequency-selective circuits. These high-Q coils provide:
Tight inductance tolerances for stable tuned performance
Very high self-resonant frequencies
Excellent temperature stability
Reliable operation in high-frequency environments
Manufactured in accordance with MIL-C-15305, these precision RF coils are available in tape-and-reel packaging to support automated assembly processes.
Whether supporting impedance control, filtering, or frequency-selective designs, ECI delivers high-reliability RF inductors engineered for mission-critical performance.
