Key Features
- 430 nH inductance with tight ±2% tolerance ensures precise RF filter and impedance-matching performance
- Ultra-low DCR of 15.5 mΩ minimizes power loss, supporting up to 4.3 A DC current without significant heating
- Air-core construction eliminates saturation effects, maintaining linear inductance at high current levels
- Compact 2929 (5230) rectangular package suits space-constrained RF and power-conditioning PCB layouts
Applications
The 2929SQ-431GEB is designed for RF filtering, impedance matching, and choke applications in wireless communication modules, power amplifiers, and high-frequency DC-DC converters. Its air-core construction and low DCR of 15.5 mΩ make it well-suited for high-current RF choke circuits operating from 1 MHz to several hundred MHz. The compact rectangular package also fits into noise-suppression networks on low-noise amplifier (LNA) input stages.

Frequently Asked Questions
What is the inductance, current rating, and DCR of the 2929SQ-431GEB?
The 2929SQ-431GEB provides 430 nH (0.43 µH) of inductance at ±2% tolerance, handles up to 4.3 A DC current, and has a DC resistance of just 15.5 mΩ (0.0155 Ω), making it a low-loss choice for RF choke and filter applications where both current capacity and high-frequency efficiency matter.
Why does the air-core construction of 2929SQ-431GEB matter for high-current RF applications?
Air-core inductors like the 2929SQ-431GEB exhibit no magnetic saturation since there is no ferrite or iron core to saturate, maintaining the full rated 430 nH inductance even at the maximum 4.3 A operating current, which is essential in power amplifiers and RF front-end circuits where inductance roll-off under load would degrade linearity and gain.
In which frequency range does 2929SQ-431GEB perform as an RF inductor, and what design scenarios benefit most?
Air-core inductors in the 430 nH range typically maintain useful Q factors from about 10 MHz to 500 MHz, making the 2929SQ-431GEB appropriate for VHF/UHF bandpass filters, impedance-matching networks in 100 MHz to 400 MHz transceivers, and RF chokes in power supplies serving wireless modules operating at 2.4 GHz or 5 GHz bands.
