Jianghai CD 297 Series Capacitor
105°C, Miniaturized, Long Life, Snap-inDistributor's Insight
FAE Review: The CD 297 strikes a fantastic balance. It provides the same long-life rating as the larger CD 295 but in a more compact package. We see this series used extensively in high-density power supplies and in the auxiliary power circuits of solar inverters, where board space is at an absolute premium but reliability cannot be compromised. If you need a long-life capacitor and are struggling with PCB layout, the CD 297 is your answer.
Description & Specifications
With the continuous trend of miniaturization in electronics, the CD 297 series was developed to meet the need for smaller, high-performance components. It delivers a useful life of 5000 hours at 105°C, making it suitable for professional and industrial equipment with long service life requirements but limited physical space. Typical applications include ballasts, LED drivers, and compact power modules.

Frequently Asked Questions (FAQ)
Q: What is the trade-off for the smaller size of the CD 297?
A: The primary trade-off for the reduced case size, when compared to a series like the CD 295 of the same CV rating, is typically a lower ripple current handling capability. The smaller can has less surface area to dissipate heat. Therefore, it's best for applications where long life is needed but ripple current stress is moderate.
