Telecommunications
5G base stations, optical transport networks, and data center switching equipment rely on KEMET capacitors for power supply decoupling, signal filtering, and energy storage. Our C0G/NP0 ceramic capacitors maintain stable capacitance across the full operating temperature range critical for outdoor telecom installations.
Key Component Requirements
| Parameter | Requirement | KEMET Solution |
|---|---|---|
| Temperature Range | -40C to +125C | C0G/X7R ceramic series |
| ESR | Less than 10 milliohm | T520/T530 polymer tantalum |
| Ripple Current | Greater than 3A RMS | ALC70 screw terminal electrolytic |
Automotive
Every ADAS module, battery management unit, and infotainment system requires AEC-Q200 qualified passive components. KEMET supplies automotive-grade ceramic capacitors with flex termination to survive board-level thermal shock, and tantalum capacitors with controlled ESR for high-frequency power rail decoupling in 48V mild-hybrid architectures.
Material Comparison for Automotive Power Rails
| Technology | Advantage | Trade-Off |
|---|---|---|
| MLCC (X8R) | Highest volumetric efficiency | DC bias derating at rated voltage |
| Polymer Tantalum | Stable capacitance, benign failure | Higher cost per microfarad |
| Hybrid Aluminum | Best capacitance per dollar | Larger footprint, ESR drift over life |
Industrial
Motor drives, solar inverters, and programmable logic controllers demand capacitors that withstand high ripple currents and voltage transients. KEMET electrolytic capacitors with 10,000-hour life ratings at 105C provide the bulk energy storage these applications require, while our power inductors handle sustained current without saturation.
Medical
Implantable cardiac devices, patient monitoring equipment, and diagnostic imaging systems need components with ultra-low leakage current and guaranteed long-term stability. KEMET medical-grade tantalum capacitors offer sub-microampere DC leakage and are manufactured in ISO 13485 aligned processes.
Aerospace & Defense
Mission-critical avionics and space-qualified systems require MIL-PRF-55365 and MIL-PRF-123 rated capacitors. KEMET supplies established reliability (ER) tantalum capacitors with 1% failure rate levels for applications where replacement is impossible.
