Capacitor Products and Systems Certification Services

Purpose of capacitor certification

Capacitors are energy-storing devices that are widely used in electronic equipment. With the rising demand for electricity including electricity from renewable energy sources has placed a higher demand on the current power generation infrastructure and its manufacturers. Through capacitor certification services, we can help deliver the right capacitor solution for products and systems with options for distinct levels of certification. These options allow end-product manufacturers and integrators to strategically choose the most effective solution to meet the most demanding requirements for cost and performance to enter the markets.

A capacitor with UL Certification may allow for:

Reduction in product testing for the end-product manufacturer
Knowledge of end-product safety criteria
Reduction in product costs for end-product manufacturers
Increase in available capacitor options

Capacitor certification overview

Our capacitor certification services cover integral protection capacitors with either segmented film or expansion-type protection, which are intended for use with products such as:

Appliances
Lighting equipment
Air conditioning and refrigeration equipment
Motors
Electrolytic capacitors for motor start or similar applications
DC power capacitors with or without integral protection intended for use in DC power electronic applications such as switching circuits, DC filtering and renewable energy systems

Capacitor certification requirements for compliance

Capacitors are evaluated to the following Standards for compliance and safety:

U.S. — UL 810 the Standard for Capacitors
Canada — CSA C22.2 No. 190

We provide services for the capacitors described above, as well as extensive knowledge in the end-product requirements and help to market with a reduction in product testing for the end-product manufacturer.
