Overview
The KEMET SSHB21HS-R05910 is a dual-mode common mode filter choke designed for AC line applications. It features an inductance of 91 mH at a test frequency of 10 kHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance of 1.88 Ohms and operates within a temperature range of -25°C to +120°C. Rated for 250 VAC, it utilizes through-hole mounting with dimensions of approximately 26 mm length, 23 mm width, and 15.5 mm height.
Feature Summary
- Dual-mode filtering capability combining common and differential mode suppression
- Compact hybrid coil construction for efficient space utilization
- Through-hole termination for secure PCB integration
Applications
- Utility metering systems for electricity, gas, and water
- AC line input filtering in residential and commercial equipment
- Power supply noise reduction in sensitive electronic devices
Procurement Notes
Verify the specific suffix R05910 against official KEMET documentation to confirm the 91 mH inductance and 500 mA rating. Ensure the procurement specification matches the required 250 VAC voltage rating and through-hole package type. Cross-reference the datasheet for exact dimensional tolerances and thermal characteristics before finalizing orders.
Selection Notes
Select this component when high impedance common mode attenuation is required alongside differential mode filtering in compact spaces. The dual-mode design simplifies circuit topology by reducing the need for separate filters. Consider the 500 mA current limit and 1.88 Ohm DCR for power loss calculations. Verify compatibility with the target operating temperature range of -25°C to +120°C.
Part Context
This part belongs to the KEMET SSHB21HS series of AC line filters. These coils are characterized as hybrid designs offering versatile filtering characteristics. The series is engineered for compact, low-profile applications requiring effective EMI suppression in AC power lines.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult KEMET technical support or authorized distributors for validated cross-references that match the 91 mH inductance, 500 mA current rating, and dual-mode specifications.
