SSHB21H-18054

Overview

The KEMET SSHB21H-18054 is a through-hole common mode choke from the SSHB21H series. It features an inductance of 5.4 mH at 10 kHz and supports a maximum DC current of 1.8 A. The component has a maximum DC resistance of 220 mOhm and operates within a temperature range of -40°C to 120°C. Rated for 250 V AC, it utilizes a hybrid coil design with a divided bobbin to achieve high impedance across a wide frequency range.

Feature Summary

• Dual-mode operation suppressing both common and normal mode noise
• Hybrid coil construction with divided bobbin for wide frequency impedance
• Through-hole mounting for robust mechanical integration

Applications

• Power supply line filtering
• Electromagnetic interference suppression in electronic circuits
• Noise reduction in AC/DC conversion stages

Procurement Notes

Verify the specific part number against official KEMET documentation to confirm electrical ratings and physical dimensions. Ensure compatibility with your circuit's current and voltage requirements before procurement. Cross-reference datasheets for accurate thermal and impedance characteristics.

Selection Notes

Select this component when dual-mode noise suppression is required in through-hole designs. Consider the 1.8 A current rating and 220 mOhm resistance for power loss calculations. Verify that the operating temperature range meets environmental conditions.

Part Context

This component belongs to the KEMET SSHB21H series of hybrid common mode chokes. These coils are engineered to provide effective noise cancellation by addressing both common and normal mode disturbances simultaneously, making them suitable for sensitive electronic applications requiring reliable EMI performance.

Replacement Considerations

Consult official KEMET substitution guides or equivalent manufacturer catalogs for verified alternatives. Ensure any replacement matches the 5.4 mH inductance, 1.8 A current rating, and through-hole package constraints.
