PMR209ME6470M100R30

Overview

The KEMET PMR209ME6470M100R30 is a first-order RC EMI/RFI filter designed for through-hole mounting. It features a radial package with a 25.4 mm lead spacing. The component integrates a 470 nF capacitor and a 100 Ohm resistor, offering a capacitance tolerance of ±20% and a resistance tolerance of ±30%. Rated for 250 VAC and 630 VDC, it utilizes metalized paper dielectric technology. The unit operates within a temperature range of -40°C to +85°C and measures 30.5 mm in length, 15.3 mm in width, and 22 mm in height.

Feature Summary

• Integrates a 470 nF capacitor and 100 Ohm resistor into a single first-order low-pass network for effective EMI suppression.
• Constructed with metalized paper dielectric to ensure reliability under specified AC and DC voltage ratings.
• Designed for through-hole installation with radial leads spaced at 25.4 mm for standard PCB compatibility.

Applications

• General-purpose electromagnetic interference filtering in electronic circuits
• Power supply input stages requiring common-mode noise reduction
• Industrial equipment signal conditioning

Procurement Notes

Verify the specific suffix R30 against official KEMET documentation to confirm lead form and packaging configuration. Ensure the 25.4 mm lead spacing matches the target PCB footprint. Confirm that the 250 VAC rating aligns with the application's line voltage requirements. Check for RoHS compliance status if restricted substances are a constraint. Validate the operating temperature range against environmental conditions.

Selection Notes

Select this component when a discrete RC filter solution is preferred over integrated modules for cost or space optimization. The 470 nF value provides significant attenuation for high-frequency noise while the 100 Ohm resistor limits inrush current. Consider the physical dimensions of 30.5 x 15.3 mm for board layout constraints. The radial package simplifies manual assembly or wave soldering processes compared to surface mount alternatives.

Part Context

This part belongs to the KEMET PMR209 series of RC EMI filters. The series offers various combinations of capacitance and resistance values tailored for different noise profiles. Other variants in the family include different capacitor values such as 100 nF or 47 nF, paired with resistors like 47 Ohm or 330 Ohm, allowing designers to tune the cutoff frequency for specific applications.

Replacement Considerations

Direct substitutes within the PMR209 series include PMR209MC6100M100R30 (100 nF) or PMR209ME6470M220R30 (470 nF, 220 Ohm). Verify that any replacement maintains the same lead spacing and voltage ratings. Cross-reference datasheets to ensure identical physical dimensions and thermal characteristics before integration.
