Jianghai CD 296 Series Capacitor
105°C, High Ripple Current, Snap-in Aluminum ElectrolyticDistributor's Insight
FAE Review: The CD 296 is our go-to series when a customer's primary concern is managing high ripple current in a compact PCB footprint. Compared to general-purpose series, the CD 296 offers a significantly higher Irms rating for the same capacitance and voltage. This makes it invaluable for the output stages of hard-switching power supplies where ripple stress is the main cause of capacitor heating and failure.
Description & Specifications
The Jianghai CD 296 series is specifically engineered to handle high levels of ripple current, a critical requirement for modern power electronics. By using an advanced electrolyte and construction techniques, this series can dissipate heat more effectively, allowing it to operate reliably under heavy electrical stress. It's an ideal choice for high-frequency SMPS, industrial welding equipment, and inverter output stages.

Frequently Asked Questions (FAQ)
Q: If the CD 295 has a longer load life (5000h vs 3000h), why would I choose the CD 296?
A: It's a trade-off. The CD 296 is designed to handle significantly more ripple current. In an application where ripple current is high, a CD 295 might overheat and fail much faster than its rated life, whereas the CD 296 would operate within its safe limits. You choose the series based on the primary stress factor in your application: is it ambient temperature (favoring CD 295's longevity) or ripple current (favoring CD 296's robustness)?
Q: How does case size compare for the same CV rating?
A: Often, the CD 296 can achieve a higher ripple current rating in a smaller case size compared to a general-purpose capacitor of the same capacitance and voltage (CV). This is a key advantage for space-constrained designs.
