• Utilizes radial through-hole mounting for secure mechanical attachment
• Engineered for high impedance performance at specific frequencies

Applications

• DC power line filtering
• Signal line noise reduction
• Electronic equipment EMC mitigation

Procurement Notes

Verify the exact part number suffix and manufacturer specifications against official Taiyo Yuden documentation before procurement. Confirm that the component meets required RoHS compliance standards for your region. Ensure that the through-hole package dimensions and pin spacing are compatible with your PCB layout constraints. Check for any recent product discontinuance notifications or lifecycle status updates from the manufacturer to ensure long-term availability.

Selection Notes

Select this component when designing circuits requiring robust common mode noise attenuation on DC and signal lines. Consider the 300 mA current rating and 3 Ohm DC resistance to ensure minimal voltage drop and thermal issues under load. Verify that the 40 kOhm impedance at 700 kHz aligns with the noise frequencies present in your application. Ensure the operating temperature range of -25°C to +105°C covers the environmental conditions of the final device.
