| High Light | SMT conical inductor 470nH ultra-wideband ，RF choke conical inductor 40GHz+ ，flexible mounting conical inductor flying leads | ||
The HALT40012 brings the resonance-free performance of tapered conical winding to automated assembly lines. With flexible mounting options covering both SMT pads and flying leads, this 470nH broadband choke sustains continuous RF blocking from 50 MHz through 40 GHz while fitting into high-volume optical transceiver and microwave module production.
The tapered cone winding distributes turn-to-turn capacitance along a mechanical gradient rather than concentrating it at a single LC node. The result: no self-resonance notch, no mid-band S21 dip, and a self-resonant frequency beyond 40.0 GHz. VNA verification on TRL-calibrated microstrip fixtures confirms flat through-line insertion loss across the full 0.05-40.0 GHz rated span, with RF-DC isolation exceeding 1.5 kΩ throughout the band.
Every parameter can be tailored to your design. Customization options include:
Typical customization cycle: engineering review within 24 hours, prototype samples in 5-7 working days, production lots in 15-25 working days. Each custom variant is VNA-characterized and shipped with its own .s2p data file.
