Redesigning for Space? Try jb Small-Size SMD Capacitors with Stable Performance and Compact Fit
When PCB space is tight, component selection becomes more than just a size issue—it’s about performance, endurance, and thermal stability. jb capacitors offers a range of small-size SMD aluminum electrolytic capacitors that combine compact dimensions with application-specific strengths.
The JCG, JCX, and JCY series are all surface-mount electrolytic capacitors built for modern compact layouts. While their sizes may be similar, each is optimized for different technical priorities.
JCG Series – Long Life
- Endurance: 7000 hours at 105°C
- Voltage range: 6.3V ~ 50V
- Designed for extended product lifespans in dense circuit designs.
JCX Series – Wide Temperature
- Operating temp: -55°C to +105°C
- Endurance: 2000 hours at 105°C
- Suitable for products exposed to varying or extreme temperatures.
JCY Series – High Ripple Tolerance
- Ripple current optimized
- Operating temp: -55°C to +105°C
- Designed for circuits with high ripple stress, such as switching power supplies.
Key Features Shared by All Series
- Surface-mount (SMD) aluminum electrolytic construction
- Compact case sizes
- Reflow soldering compatibility
- RoHS compliant
Choosing the Right Model
While all three series are compact and SMD-compatible, the functional differences matter. Below is a summary to help guide selection:
| Series | Key Feature | Endurance @ 105°C | Temp Range | Ripple Current Tolerance | Recommended Use Case |
| JCG | Long lifespan | 7000 hours | -40°C to +105°C | Moderate | Applications needing long-term stability |
| JCX | Wide operating range | 2000 hours | -55°C to +105°C | Moderate | Harsh or varying thermal conditions |
| JCY | High ripple durability | 2000 hours | -55°C to +105°C | High | High-ripple environments (e.g. SMPS) |
For engineers and sourcing teams, understanding these differences enables better layout planning and long-term component reliability.
