What are the key features of 2929SQ-501JEB?
- 500 nH inductance with only 16.5 mΩ DCR enabling high-efficiency RF choke and power-filter stages with minimal resistive loss
- 4.3A current handling in a compact 5530 rectangular air-core construction for high-current RF and DC power line filtering
- RoHS-compliant Pb-free build with 5% inductance tolerance for consistent RF impedance performance across production batches
What is 2929SQ-501JEB used for?
The 2929SQ-501JEB is designed for RF filtering and impedance matching networks in wireless transceivers, where its 500 nH air-core inductance and low 16.5 mΩ DCR minimize insertion loss across RF signal paths. It is also suitable as an output inductor in high-current DC-DC converters and EMI suppression chokes on power supply rails that demand a 4.3A capable component with a compact 5530 footprint.

Frequently Asked Questions
What inductance value and DCR does the 2929SQ-501JEB offer for RF power filter design?
The 2929SQ-501JEB provides 500 nH nominal inductance with a ±5% tolerance and an extremely low DC resistance of only 16.5 mΩ, which minimizes I²R losses at full 4.3A load current, making it suitable for both RF choke duty and high-efficiency DC power rail filtering.
How much current can the 2929SQ-501JEB handle, and how does air-core construction benefit RF applications?
Rated at 4.3A saturation current, the 2929SQ-501JEB uses an air-core construction that eliminates magnetic saturation entirely, maintaining stable 500 nH inductance from milliamp signal levels up to multi-amp power currents, which is essential for linear RF performance in transmitter output matching networks.
Which RF or power-supply design scenarios favor the 2929SQ-501JEB over a shielded power inductor?
When board layout can tolerate minor electromagnetic emissions and maximum inductance linearity at 500 nH with 4.3A capability is needed at the lowest possible DCR of 16.5 mΩ, the unshielded air-core 2929SQ-501JEB outperforms shielded ferrite inductors that exhibit permeability roll-off and higher DCR in the same footprint.
What case size and footprint does the 2929SQ-501JEB occupy on a PCB?
The 2929SQ-501JEB uses the 5530 case code (approximately 5.5 mm × 3.0 mm rectangular SMD footprint), which provides a moderate component height and allows placement in tight RF board layouts where a conventional through-hole inductor would occupy significantly more area.
