The KEMET PMR209MC6220M220R30 is a first-order RC EMI/RFI filter designed for through-hole mounting. It features a capacitance of 220 nF and a resistance of 220 ohms with ±30% tolerance. Rated for 250 VAC and 630 VDC, the component utilizes metalized paper foil dielectric technology. The radial package measures 24.00 mm in length, 11.30 mm in width, and 16.50 mm in height. It operates within a temperature range of -40°C to +85°C and holds certifications including UL, VDE, and RoHS.
Verify the specific resistance value against design requirements, as the PMR209 series includes variants with different resistance ratings such as 22 ohms or 47 ohms. Confirm that the 220-ohm resistance aligns with the target impedance and current handling needs. Ensure the 250 VAC rating is sufficient for the intended line voltage. Check for required safety certifications like UL or VDE based on regional compliance standards before finalizing procurement.
Select this component when a combined RC network is preferred over discrete components to save space. The 220-ohm resistance provides significant damping compared to lower-resistance alternatives. Consider the physical dimensions of the radial package to ensure compatibility with the PCB footprint. Verify that the operating temperature range meets the environmental conditions of the application.
This part belongs to the KEMET PMR209 series of RC EMI filters. These components are distinct from standard film capacitors by integrating a resistive element directly in series with the capacitance. The series offers various combinations of capacitance and resistance values to tailor filtering characteristics for different noise profiles and load requirements.
Direct substitutes must match the 220 nF capacitance, 220 ohm resistance, and radial package dimensions. Other manufacturers may offer similar RC networks, but pin spacing and voltage ratings must be verified. Cross-referencing with other PMR209 variants requires checking if the resistance value difference impacts the circuit's cutoff frequency and damping factor.
