Overview
The NFM31KC223R1H3L is a feedthrough capacitor from the Murata EMIFIL NFM31 series, designed for surface mount installation in a 1206 (3216 Metric) package with three PCB pads. It features a capacitance of 0.022 µF with a ±20% tolerance and a rated voltage of 50V DC. The component supports a current rating of 10 A and has a maximum DC resistance of 1.5 mOhm. It operates within a temperature range of -55°C to 125°C and meets AEC-Q200 standards.
Feature Summary
- Provides electromagnetic interference suppression through a feedthrough capacitor architecture.
- Supports high current handling capabilities suitable for power line filtering applications.
- Complies with automotive reliability standards including AEC-Q200 qualification.
Applications
- Power supply input filtering
- DC-DC converter output noise reduction
- Automotive electronic system EMI suppression
Procurement Notes
Verify the specific suffix 'R1H3L' against official Murata documentation to confirm exact electrical tolerances and termination specifications. Ensure compatibility with standard 1206 footprint dimensions during layout. Confirm RoHS3 compliance status if required by project regulations. Cross-reference datasheet revision dates to ensure parameter accuracy.
Selection Notes
Select this component when high current capacity is required alongside compact surface mount integration. The 1206 package offers a balance between thermal performance and board space efficiency. Consider the 10 A rating for direct power rail connections where lower impedance is critical for effective noise attenuation.
Part Context
This part belongs to the Murata EMIFIL NFM31 series of feedthrough capacitors. These components are engineered for high-performance EMI suppression in compact form factors. The series is widely utilized in automotive and industrial electronics requiring robust filtering solutions that can withstand significant current loads without degradation.
Replacement Considerations
NFM31HK223R1H3L: Similar capacitance and voltage but rated for 6 A current instead of 10 A. Verify current requirements before substitution as the HK variant has lower current handling capability despite identical physical dimensions and capacitance values.
