Low ESR, High Reliability – Two Compact Capacitor Solutions from jb

 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?

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

Why Low ESR Matters

Lower ESR means:

• Less heat under continuous current

• Improved filtering performance at high frequencies

• Better power efficiency across system load variations

This makes the JEA and JEB series ideal not just for space-constrained designs, but also for applications that demand stable ripple suppression and long-term thermal endurance.
