# Industrial Specification: EMI Filter Panel

## 1. Technical Definition
A specialized panel component designed to suppress electromagnetic interference (EMI) within shielded enclosures.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **30-100 dB attenuation at 150 kHz-30 MHz, 85-264 VAC input, -40°C to +85°C ambient**. Failure boundary: **Attenuation drops below 20 dB at 1 MHz, leakage current exceeds 3.5 mA at 250 VAC, insulation resistance falls below 100 MΩ at 500 VDC**, Mechanism: **Dielectric breakdown in X/Y capacitors at &gt;275 VAC RMS, core saturation in common-mode chokes above 10 A RMS, thermal degradation of ferrite materials at &gt;125°C Curie point**.

### 2.1 Analytical Physics Model
Governed by the **EMI Shielding Effectiveness (SE)**:

> **Primary Equation**: $SE = 20 \log(\frac{E_{in}}{E_{out}})$  
> **Engineering Impact**: Ensures control stability in high-frequency inverter zones.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| E_{in} | Incident Field | Engineering Constant |
| E_{out} | Transmitted Field | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Transient voltage surge exceeding 6 kV/3 kA per IEC 61000-4-5 | 8 | Varistor degradation causing leakage current &gt;10 mA, capacitor dielectric puncture | Multi-stage protection with gas discharge tubes (GDTs) rated 8/20 μs, series impedance of 10 Ω minimum |
| High-frequency common-mode noise above 30 MHz bypassing filter cutoff | 8 | Radiated emissions exceed CISPR 32 Class B limits by 15 dBμV/m | Pi-filter topology with 2.2 μH differential chokes, shielded compartmentalization using Mu-metal ≥0.5 mm thickness |
