PMR210MB5220M100R30

Overview

The KEMET PMR210MB5220M100R30 is an RC EMI suppression capacitor from the PMR210 series. It features a capacitance of 22 nF with ±20% tolerance and a built-in 100 Ohm resistor. Rated for 250 V AC and 250 V DC, it utilizes metallized paper dielectric. The component supports through-hole mounting with a 15.2 mm lead pitch and 0.8 mm lead diameter. Physical dimensions are 18.5 mm length, 13 mm height, and 7.3 mm depth. It operates up to 115°C and holds IEC 60286-2 and UL certifications.

Feature Summary

• Integrates a 100 Ohm resistor within the X1 safety capacitor structure for combined filtering
• Utilizes metallized paper dielectric for reliable high-voltage suppression performance
• Designed for through-hole installation with standardized radial lead spacing

Applications

• First-order low-pass RC EMI filtering in electronic circuits
• Noise suppression in AC power line interfaces
• Component integration in devices requiring X1 class safety certification

Procurement Notes

Verify the complete part number PMR210MB5220M100R30 against official KEMET documentation to confirm specifications. Ensure compatibility with required voltage ratings and thermal limits. Check for specific ordering suffixes that may affect packaging or compliance status. Confirm lead pitch and physical dimensions match the target PCB layout requirements before procurement.

Selection Notes

Select this component when an integrated RC network is required for first-order low-pass filtering. The 100 Ohm internal resistance distinguishes it from standard capacitors. Verify that the 250 V AC rating meets the application's line voltage needs. Consider the 115°C maximum operating temperature for thermal management. Ensure the through-hole package fits the assembly process constraints.

Part Context

This component belongs to the KEMET PMR210 series of metallized paper RC suppression capacitors. These parts combine X1 safety capacitor functionality with a series resistor. The series is designed for general-purpose EMI suppression where both capacitance and resistive damping are necessary. It serves as a compact solution for noise reduction in AC-powered equipment.

Replacement Considerations

Cross-reference with other KEMET PMR210 variants sharing the same 22 nF capacitance and 100 Ohm resistance. Verify that substitute parts maintain the X1 suppression class and 250 V AC rating. Ensure physical dimensions and lead pitch compatibility for direct replacement.
