Overview
The KEMET SSHB21H-R051100 is a single-phase AC line filter designed for through-hole mounting. It features a high impedance common mode choke with an inductance of 110 mH at 10 kHz and a maximum DC resistance of 2.1 Ohms. Rated for a continuous current of 500 mA and a voltage of 250 VAC, this component operates within a temperature range of -25°C to +120°C. The physical dimensions are 23.0 mm x 23.0 mm x 14.5 mm, ensuring a compact footprint suitable for space-constrained electronic assemblies requiring EMI suppression.
Feature Summary
- High impedance common mode filtering for effective noise attenuation
- Dual-mode operation capability for enhanced signal integrity
- Through-hole construction for robust mechanical stability
Applications
- Single-phase AC power line filtering
- EMI suppression in compact electronic devices
- Power supply input stages
Procurement Notes
Verify the specific suffix R051100 matches the required 110 mH inductance and 500 mA rating. Confirm RoHS compliance status if restricted materials are prohibited. Ensure the through-hole package dimensions fit the target PCB layout. Check for any specific handling requirements regarding the operating temperature range up to 120°C during assembly and operation.
Selection Notes
Select this component when high inductance is required for significant common mode noise reduction in low-current applications. The 2.1 Ohm DC resistance must be evaluated against allowable voltage drop constraints. Consider the thermal performance given the 60 K temperature rise specification under rated load conditions compared to lower inductance alternatives.
Part Context
This part belongs to the KEMET SSHB21H series of high impedance AC line filters. These components are characterized by their compact size and lightweight design, making them suitable for modern electronics where space is limited. The series offers various inductance values tailored for different noise profiles while maintaining consistent physical footprints for design flexibility.
Replacement Considerations
The UALSB2R0511000 is identified as an alternative part number for this component. Verify electrical equivalence, specifically the 110 mH inductance and 500 mA current rating, before substitution. Ensure mechanical compatibility with existing through-hole mounting structures.
