Discover jb’s JEA & JEB polymer aluminum SMD capacitors. Compact, low ESR, and thermally stable for reliable power filtering.

In high-efficiency electronics, stability under stress isn’t optional—it’s expected. Whether it’s power supply filtering or circuit decoupling, engineers rely on components that can maintain performance over time, especially under elevated temperatures and compact board conditions.

That’s where jb’s polymer aluminum SMD solid capacitors step in, offering a powerful combination of low ESR, thermal stability, and form factor flexibility.

 Meet JEA and JEB – Two Designs, One Reliability Standard

The JEA and JEB series from jb are purpose-built to support designers working across a range of power-critical applications. Both series are:

• Rated for 2000 hours at 105°C

• Built with low ESR construction for smoother power delivery

• Available in SMD form factors that suit modern board layouts

But what sets them apart?

Polymer Aluminum Capacitor Selection Guide & Comparison

Selecting between the JEA and JEB series depends primarily on your PCB vertical clearance limitations and required ripple current capacity.

Series	Profile	Capacitance	Best Fit For
JEA	1.9mm	2.2µF–470µF	Compact spaces, slim modules
JEB	2.8mm	6.8µF–680µF	Higher ripple current needs

Detailed Application Scenarios

• Ultra-Slim Consumer Electronics & Displays: The low 1.9mm profile of the JEA series makes it ideal for thin LCD displays, wearable smart devices, and ultra-portable power modules.
