MET-11 - Tamura

MET-11 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the MET-11?
  Tamura recommends a symmetrical PCB layout with the primary and secondary windings on opposite sides of the board, and the sense pins connected to a low-impedance path to minimize noise and ensure accurate current measurement.
• How do I ensure accurate current measurement with the MET-11 in high-frequency applications?
  To ensure accurate current measurement in high-frequency applications, use a low-pass filter or a shielding technique to minimize electromagnetic interference (EMI) and radio-frequency interference (RFI) effects on the sense pins.
• What is the maximum operating temperature range for the MET-11?
  The MET-11 has an operating temperature range of -40°C to 125°C, but derating is required above 85°C. Consult the datasheet for specific derating guidelines.
• Can I use the MET-11 in a high-voltage application?
  The MET-11 is designed for low-voltage applications up to 100V. For high-voltage applications, consider using a different current sense transformer or consult with Tamura's application engineers for custom solutions.
• How do I calculate the power loss in the MET-11?
  Power loss in the MET-11 can be calculated using the formula: P_loss = I_primary^2 * R_primary + I_secondary^2 * R_secondary, where I_primary and I_secondary are the primary and secondary currents, and R_primary and R_secondary are the primary and secondary resistances.
