| Brand Name: | Hoan |
| Model Number: | HALT60008 |
| MOQ: | 10 Pieces |
| Payment Terms: | L/C,D/A,D/P,T/T,Western Union |
| Supply Ability: | 50000 Pieces per Month |
The HALT60008 is a broadband conical inductor for production programs requiring consistent RF performance, configurable specifications, and predictable supply chain logistics. It delivers 1800 nH (1.8 µH) of nominal inductance with a ±20% tolerance at 10 MHz, wound with 0.08 mm (80 µm) oxygen-free copper wire in a continuously tapered air-core conical geometry.
The conical winding distributes parasitic turn-to-turn capacitance along the 3.0 mm winding length rather than concentrating it at a single LC product. This enables flat, resonance-free RF isolation from 10 MHz to 20 GHz in a single component—replacing the 3–5 cascaded inductors and their associated junction resonances that conventional broadband bias tee designs require.
Rated for 500 mA of continuous DC bias current (temperature rise limited to ΔT ≤ 15°C), the HALT60008 supports bias networks for GaN and GaAs power amplifiers, high-current optical transceiver laser drivers, and PIN diode switch DC return paths. The air-core architecture ensures inductance remains stable across the full 0–500 mA DC range with no magnetic saturation effects. Operating temperature spans -55°C to +125°C for industrial and defense applications.
The manufacturing process uses optically guided closed-loop winding with automated taper profile control, maintaining CpK values exceeding 1.67 for critical dimensions. Each production lot undergoes sample-based VNA acceptance testing on a characterized microstrip fixture with TRL de-embedding. A Certificate of Conformance (CoC) documenting lot number, date of manufacture, and test results ships with each order.
The HALT60008 supports custom configuration of inductance value (50–2000 nH), wire gauge (0.05–0.12 mm), lead finish (gold/tin, bare copper, enhanced gold), and packaging format (waffle pack, tape-and-reel, gel-pack). Quick-turn prototyping is available in 3–4 weeks for custom values with a 50-piece minimum. Standard production lead time is 15–25 working days. Full .s2p Touchstone data, 3D STEP models, and parameterized HFSS EM models are available for PCB co-simulation.

The conical inductor platform supports parameter adjustments for application-specific requirements. The following parameters are configurable for qualified production volumes.
Custom inductance values from 50 nH to 2000 nH are achievable by adjusting turn count and winding profile. Higher inductance values trade off upper frequency; lower inductance values trade off low-frequency isolation. Quick-turn prototyping (3–4 weeks) is available for custom values with a minimum order of 50 pieces.
| Option | Continuous DC Current | Upper Frequency Limit | Primary Use Case |
|---|---|---|---|
| 0.05 mm (ultra-fine) | 200 mA | 40 GHz | Maximum bandwidth, low-current bias |
| 0.08 mm (fine, standard) | 500 mA | 20 GHz | Balanced current and bandwidth |

Q: What is the minimum order for a custom inductance value?
A: Custom inductance prototyping requires a minimum of 50 pieces and typically ships within 3–4 weeks. Production volumes for custom values start at 500 pieces depending on winding profile complexity.
Q: Can Hoan support consigned inventory programs?
A: Yes. For annual volumes exceeding 100,000 pieces, Hoan offers consigned inventory with monthly call-off, buffer stock maintained at Hoan facility, and 72-hour emergency shipment upon request. Contact Hoan sales to discuss terms and forecast requirements.
Q: Are fully characterized samples available before committing to a production order?
A: Yes. Engineering sample quantities (10–50 pieces) can be ordered with complete .s2p characterization data. Each sample lot is measured on the same calibrated VNA microstrip fixture used for production acceptance testing, providing directly comparable data.
Q: What warranty coverage is provided?
A: Hoan warrants the HALT60008 series against defects in materials and workmanship for 12 months from the date of shipment when stored under recommended conditions (20–25°C, 40–60% RH) in original anti-static packaging.
Q: How does the HALT60008 differ from other HALT60008 variants?
A: All HALT60008-series inductors share identical core specifications (1800 nH, 0.08 mm wire, 10 MHz–20 GHz, 500 mA). The HALT60008 provides complete ordering, customization, and supply chain documentation—including wire gauge selection table, lead finish options, packaging configurations, quality documentation requirements, and payment/logistics terms. Other variants (A–G) provide application-specific technical and evaluation guidance.
