  • Telecom power supply filtering

The B82462-G4103-M from TDK/EPCOS is a 10mH surface-mount inductor specifically designed for EMI filtering in power electronics. The high 10mH inductance provides significant impedance to high-frequency conducted noise on power lines, helping equipment meet EMC standards (FCC, CISPR, EN). The G4 suffix indicates the specific package variant within the B82462 series, and 103 denotes the 10mH inductance value (10 x 10^3 µH). The M tolerance (±20%) is standard for high-inductance EMI filter inductors. The device is packaged in a surface-mount format compatible with automated PCB assembly, offering a space-efficient alternative to traditional through-hole EMI chokes. The -40°C to +125°C operating temperature range suits industrial and automotive applications.

The B82462-G4103-M operates through frequency-dependent impedance for EMI suppression:

1. Low-Frequency Operation: At DC and mains frequency (50/60Hz), the inductor presents only its DC resistance, allowing power current to flow with minimal voltage drop. The 10mH inductance presents negligible impedance at low frequencies (Z = 2πfL = 3.1Ω at 50Hz).

2. High-Frequency Noise Suppression: At EMI frequencies (150kHz to 30MHz for conducted emissions), the inductor’s impedance increases linearly with frequency. At 1MHz, the impedance is 62.8Ω, and at 10MHz it reaches 628Ω. This high impedance blocks conducted noise from propagating through the power line, forcing it to be dissipated or reflected.

3. EMI Filter Configuration: In a typical SMPS EMI filter, the inductor is combined with X-capacitors (across the line) and Y-capacitors (line to ground) to form a pi (π) or T filter network. The 10mH inductance provides the series impedance element, while the capacitors provide shunt paths for high-frequency noise. The combination achieves 40-60dB of conducted emission attenuation.

1 Terminal 1 Passive Inductor terminal (no polarity)
2 Terminal 2 Passive Inductor terminal (no polarity)
  • SMPS EMI filters: 10mH inductance in pi-filter configuration with X2 capacitors achieves CISPR 32 Class B conducted emission limits for offline switching power supplies
  • Industrial equipment: High inductance suppresses conducted noise from motor drives and inverters, meeting EN 55011 industrial EMC requirements
  • Consumer electronics: SMD package enables automated assembly of EMI filter stage in set-top boxes, LED drivers, and appliance controllers
  • Telecom power: -48V telecom power supply EMI filtering for NEBS-compliant equipment meeting GR-1089 conducted emission requirements
