Overview
The KEMET SSR21NHS-M06890 is a through-hole common mode filter choke designed for AC line applications. It features an inductance of 89 mH measured at a test frequency of 10 kHz and supports a maximum DC current rating of 0.6 A. The component has a maximum DC resistance of 1.35 ohms and is rated for 250 VAC. It operates within a temperature range of -40°C to +105°C. The physical dimensions are 23 mm in length, 23 mm in width, and 14.5 mm in height.
Feature Summary
- Provides high impedance filtering for single-phase AC lines to suppress electromagnetic interference.
- Constructed with a compact, low-profile design suitable for space-constrained PCB mounting.
- Utilizes through-hole termination for secure mechanical attachment.
Applications
- Filtering electromagnetic interference in two-line AC power applications
- AC line input stages in electronic equipment
- Common mode noise suppression in consumer electronics
Procurement Notes
Verify the specific suffix against official KEMET documentation to ensure correct inductance and current ratings. Confirm that the operating temperature range meets the environmental requirements of the target application. Check for RoHS compliance status as indicated in the manufacturer's datasheet. Ensure the through-hole footprint matches the PCB layout specifications before ordering.
Selection Notes
Select this component when a high inductance value of 89 mH is required for effective common mode noise attenuation at low currents up to 0.6 A. The 250 VAC rating makes it suitable for standard mains voltage applications. Consider the physical size constraints as the unit measures 23x23x14.5 mm. Ensure the circuit design can accommodate the 1.35 ohm DC resistance without affecting performance.
