Overview
The Murata NFE31ZT221D1E9L is a surface-mount LC (T-type) EMI filter capacitor from the NFE series. It features a capacitance of 220 pF and a rated DC voltage of 50 V. The component supports a maximum current of 6 A and operates within a temperature range of -40°C to +85°C. Housed in a 1206 (3216 metric) package with three PC pads, it utilizes a T-type circuit topology for effective noise suppression.
Feature Summary
- Utilizes a T-type circuit structure with low residual inductance for high-frequency noise suppression
- Integrates three-terminal design to achieve superior EMI filtering performance
- Suitable for dense mounting applications in digital I/O lines
Applications
- Digital input/output lines in notebook PCs
- General electronic equipment
- Communication devices
- Portable phones
Procurement Notes
Verify the specific suffix D1E9L against official Murata documentation to confirm the 50V rating and 220pF value. Ensure the 1206 footprint matches the PCB layout. Confirm RoHS compliance status if required by project specifications. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.
Selection Notes
Select this component when designing circuits requiring 50V DC rating and 6A current handling capability. The 1206 package size is appropriate for space-constrained layouts. Consider the T-type topology for applications needing effective high-frequency attenuation without excessive series resistance.
Part Context
This part belongs to the Murata NFE series of feed-through chip EMI filters. These components are designed using Murata's ceramic processing technology. The series targets EMI suppression in various electronic devices, offering integrated circuit solutions in compact surface-mount packages.
Replacement Considerations
Consult official Murata substitution guides for compatible parts within the NFE series. Verify that alternative components match the 1206 footprint, 50V rating, and 6A current capacity. Ensure electrical characteristics align with the original design requirements.
