Assistance with Safety Agency Approvals

Coilcraft products are typically not certified by UL, CSA, TUV, CE or other agencies. However, we are ready to provide data necessary to help customers obtain approvals for their finished products.

Safety standard listings generally apply to complete electronic assemblies such as power supplies, computers, modems, televisions, etc. and not specifically to the high-frequency transformers or inductors that Coilcraft manufactures. In most cases, Coilcraft products are evaluated as part of the end equipment built by our customers; the inductors or transformers are not individually listed.

Many Coilcraft parts are designed to meet specific UL / CSA / IEC or other standards and this information is noted on the particular Coilcraft data sheet.

Coilcraft can also supply a variety of specific design details in order to help customers with the approval process. The following are examples of information that demonstrate to agency examiners that an inductor or transformer is suitable for the desired equipment certification:

• List of the insulating materials.

• Description of the transformer construction, including the number of insulation layers between windings, creepage and clearance distance between windings, and spacing between terminals.

• Safety related parameters such as Hi Pot voltage.

When required by a customer, Coilcraft can obtain specific transformer listings, for example, per UL / IEC 60950 Harmonized Standard for “Safety of Information Technology Equipment.” However, doing so will not automatically qualify the end equipment for agency approval. The manufacturer still has to submit the entire product to UL for approval.
