Terms and conditions

Last updated: September 2026

These conditions apply to quotations, orders and deliveries between ConverNova and a business customer. They do not replace anything specifically agreed in writing for a particular project; where the two differ, what is written for the project wins.

1. Who these terms are between

"We" and "ConverNova" mean ConverNova SL. "You" means the company placing the enquiry or the order. These conditions are written for business customers; we do not sell to consumers.

2. Enquiries and quotations

Sending a specification places you under no obligation and costs nothing. An engineering review and a first design proposal are free.

A quotation is valid for 30 days from its date, unless it says otherwise. Prices depend on the raw material and core prices current at the time of quoting, and a quotation may be revised before acceptance if those move materially.

A quotation is an invitation to order, not an offer capable of acceptance. A contract exists when we confirm your order in writing.

Once we have confirmed an order, the specification it was confirmed against is the one we build. A change after that point is not an amendment, it is a new quotation: tell us what has moved and we will price it and date it again. That is not us refusing the change, it is the only way a delivery date stays worth anything.

3. The specification is yours, and we treat it as confidential

Everything you send us in order to obtain a design or a quotation, including waveforms, schematics, operating points and target costs, is treated as confidential. We use it to answer your enquiry, we do not disclose it to anyone outside ConverNova, and we do not use it as an example or a case study without your written agreement. This obligation continues after the enquiry ends.

You confirm in turn that you are entitled to share what you send us, and that doing so does not breach anyone else's rights.

4. The design we produce

Unless we agree otherwise in writing for a particular project, the magnetic design we develop and the know how behind it remain the property of ConverNova. You receive the component, its measured performance data, and the right to use it in your equipment without limit of quantity or of time.

Ownership of a design can be transferred to you, and often is where a project carries a separate development or tooling charge. That transfer has to be written into the quotation or the order confirmation to take effect. It is not implied by having paid for development work.

Independently of the above, the general engineering methods, calculation tools and accumulated experience that ConverNova uses remain ours, and nothing in a project transfers them.

5. Prices, taxes and payment

Prices are quoted in euros and exclude VAT, duties and transport unless the quotation states otherwise. Payment terms are those written on the quotation or the order confirmation. Late payment carries interest at the rate set by Spanish Law 3/2004 on late payment in commercial transactions.

6. Lead times

Lead times are given in good faith as estimates and are counted from the later of a confirmed order and an agreed design. Where the site says prototypes in four to eight weeks, that assumes the required cores, wire and insulation materials are available; magnetics lead times move with the core market, and we will tell you when they do.

Time is not of the essence unless we have agreed a fixed date in writing for that specific order.

7. Prototypes and samples

A prototype is built to answer an engineering question. It is representative of the design, and it is built the way the production part will be built, but it is not a qualified production part and should not be treated as one until the design is frozen and agreed.

8. Delivery, inspection and acceptance

Unless agreed otherwise, delivery is EXW our premises in Madrid, Incoterms 2020. Please inspect goods on arrival and tell us about any shortage, visible damage or obvious non conformity within 10 working days of receipt.

9. Warranty

We warrant that production parts conform to the agreed specification and are free from defects in materials and workmanship for 12 months from delivery.

Prototypes and samples are a different thing, for the reason clause 7 gives. On those our warranty is limited to replacing a unit that is defective against the specification we agreed. We do not warrant that a prototype will perform as intended inside your equipment, or that the design will scale to a production series, because those are the questions the prototype exists to answer.

Where a part is defective, we will repair it, replace it, or credit it, at our choice. The warranty does not cover a part that has been operated outside the agreed specification, modified, mechanically damaged, or subjected to conditions that were not part of the specification we designed to.

A magnetic component is designed to an operating point. If your operating point changes, tell us: the part that was right before may not be right afterwards, and that is a redesign rather than a warranty matter.

10. Liability

Our total liability arising out of an order is limited to the price paid for the goods giving rise to the claim. We are not liable for loss of profit, loss of production, loss of contracts or any indirect or consequential loss.

Nothing in these conditions limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be limited.

You remain responsible for the design of your own equipment and for qualifying the component within it. We are magnetics specialists, not the designer of your converter.

11. Compliance and export control

You are responsible for telling us if an application is subject to export control, defence or dual use restrictions, or to any sector specific approval regime, so that we can handle the enquiry accordingly.

12. Force majeure

Neither party is liable for a delay caused by something outside its reasonable control, including raw material shortages affecting cores or magnet wire. We will tell you promptly and agree a revised date.

13. Governing law and jurisdiction

These conditions are governed by Spanish law. Disputes are subject to the exclusive jurisdiction of the courts of Madrid.

14. Changes

We may update these conditions. The version that applies to an order is the one published when we confirmed that order.
