Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Atmospheric to 1.5 bar (typical for PCB mounting) |
| temperature: | -40°C to +125°C (operating), up to +155°C (storage) |
| current rating: | DC current rating (Irms) based on thermal limits |
| frequency range: | 10 kHz to 1 MHz (typical for switching applications) |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The inductance range is typically 1–100 mH with a tolerance of ±20%. The exact value depends on the application and must be confirmed with the manufacturer.
Common materials include a ferrite core, copper wire, and insulation material. These are standard for high-frequency low-loss operation.
The operating temperature range is -40 to 85°C. Above 85°C, derating is required. Verify the specific derating curve with the supplier.
The dielectric strength is specified as 500–2000 V AC for 1 minute. This is a reference range; the actual value for a specific model must be confirmed with the manufacturer.
