Film Capacitor for EV Chargers (OBC) - ECQUA Series
As environmental regulations compliance measures have been made stricter in each country, the demand for higher levels of durability and safety of individual components is increasing in the environmentally friendly vehicle market, which is expected to achieve substantial growth in future.
Our company's power source noise prevention capacitors ECQUA (automotive) series used in EV chargers (OBC) adopt a design that ensures high reliability and high end-of-life safety, thereby contributing to equipment reliability and safety.
Features of ECQUA (for automotive) series
High reliability: High humidity resistance conforming to AEC-Q200
The company's proprietary enclosure sealing technology and aluminum vapor deposition achieve high-dimensional humidity resistance along with compliance to AEC-Q200, thereby perfectly meeting automotive applications requiring high reliability.
(Al deposition + high humidity resistance enclosure)
Reduced tan δ deterioration by humidity resistance stress leads to a small temperature rise in the high-frequency loading
〇 Zn deposition and general-purpose packaging
Excessive tan δ deterioration caused by humidity resistance stress increases temperature rise in the high-frequency loading, thereby increasing the chance of short-circuit breakage.
High safety: The ECQUA series is provided with a security mechanism (fuse), which ensures the safety of the product (open failure mode).
Through a high-precision vapor deposition pattern technology, a fuse is properly placed on a deposit film so that the circuit is opened in its failure mode. This prevents a firing accident, fuming accident, etc., caused by short circuit, thereby keeping the product set sufficiently safe.
