Continue reading to explore its technical advantages, selection criteria, and why it outperforms alternatives in critical applications.
The R413R36804000M is a radial-lead film capacitor designed for EMI suppression in harsh electrical environments. Key specifications include:
| Parameter | Value | Standard |
|---|---|---|
| Capacitance | 0.68µF ±20% | IEC 60384-14 |
| Voltage Rating | 1000VDC / 300VAC | UL 60384-14 |
| Dielectric Material | Polypropylene (PP) | KEMET DS-1001 |
| Suppression Class | X1/Y2 | IEC 60384-14 |
| Temperature Range | -40°C to +110°C | KEMET R41 Series Datasheet |
| Dimensions | 32 × 18 × 33mm | MIL-PRF-19978 |
When choosing EMI suppression capacitors, consider these factors:
Safety Standards: X1/Y2 rating ensures compliance with IEC 60384-14 for across-the-line applications.
Voltage Requirements: The 1000VDC rating provides margin for voltage spikes in 230VAC systems.
Size Constraints: Compact 32mm length suits space-limited PCB designs.
Temperature Stability: PP dielectric maintains performance up to 110°C.
Used in input filtering to suppress high-frequency noise while meeting safety standards for industrial PSUs.
Protects control circuits from transient voltages in IEC 61851-1 compliant chargers.
Mitigates EMI in 300VAC three-phase systems per IEEE 1547 standards.
According to Mordor Intelligence, the global EMI filter market will grow at 6.8% CAGR through 2028, driven by:
Stricter CISPR 32/EN 55032 regulations
Expansion of 5G infrastructure requiring robust filtering
Increased adoption of Class X/Y capacitors in consumer IoT
| Model | Capacitance | Voltage | Size | Advantage |
|---|---|---|---|---|
| R413R36804000M | 0.68µF | 1000VDC | 32×18×33mm | Higher voltage margin |
| Competitor A | 0.47µF | 760VDC | 30×15×27mm | Smaller footprint |
| Competitor B | 1.0µF | 630VDC | 35×20×35mm | Higher capacitance |
Key Takeaway: The R413R36804000M offers optimal balance between voltage rating and capacitance density for industrial applications.
Per IEC 60384-14, X1 indicates suitability for high impulse applications (≥4kV), while Y2 certification allows use between line and ground with 150VAC working voltage.
No. The 300VAC rating makes it suitable only for single-phase 230VAC or lower voltage applications.
Yes. KEMET's R41 series complies with RoHS 3 (2015/863/EU) per manufacturer documentation.
Typical MTBF exceeds 100,000 hours at 85°C when operated within rated parameters (per KEMET reliability reports).
No. This model isn't AEC-Q200 qualified. For automotive applications, consider KEMET's AY1 series.
Emerging developments in EMI suppression components include:
Higher Temperature Ratings: Demand for 125°C capable components grows with EV power electronics.
Miniaturization: Thinner PP films enabling higher capacitance in same footprint.
Smart Filtering: Integrated sensors for capacitor health monitoring (Industry 4.0).
The R413R36804000M represents KEMET's commitment to reliable EMI suppression in critical power applications. With its robust X1/Y2 safety rating, high-voltage tolerance, and stable PP dielectric, it addresses both current regulatory requirements and future design challenges.
