SU9HF-07015

Overview

The KEMET SU9HF-07015 is a through-hole common mode choke designed for power line filtering applications. It features an inductance of 1.5 mH measured at 1 kHz and supports a maximum rated current of 700 mA. The component has a DC resistance (DCR) of 440 milliohms and operates within a temperature range of -25°C to 120°C. Rated for AC voltages up to 250 V, it utilizes a vertical package with four pins and measures 17.00 mm in length, 15.50 mm in width, and 12.00 mm in height.

Feature Summary

• Provides effective noise suppression for dual-line power circuits through common mode filtering capabilities
• Constructed with a robust bobbin design suitable for high-reliability through-hole mounting requirements
• Engineered to handle continuous currents up to 700 mA while maintaining low impedance characteristics

Applications

• Power supply input filtering for electronic equipment
• Noise reduction in AC mains connected devices
• EMI suppression in industrial control systems

Procurement Notes

Verify the specific suffix codes against official KEMET documentation to ensure correct pin configuration and tolerance levels. Confirm that the operating environment remains within the specified -25°C to 120°C thermal limits. Ensure PCB layout accommodates the vertical form factor dimensions of 17.00 mm by 15.50 mm. Cross-reference the 440 millohm DCR value with circuit requirements to prevent excessive voltage drop during operation.

Selection Notes

Select this component when designing circuits requiring through-hole common mode chokes for power lines. The 1.5 mH inductance at 1 kHz provides adequate attenuation for standard EMI frequencies. Consider the 700 mA current rating to ensure safe operation under peak load conditions. The vertical orientation facilitates compact board integration where space constraints exist alongside thermal management needs.
