KNF32050-W3

Overview

The KNF32050-W3 is a surface-mount LC EMI filter manufactured by KYOCERA AVX. It features a low-pass configuration with a capacitance of 130pF and a current rating of 200mA. The component utilizes a 1206 (3216 Metric) package size, measuring 3.2mm in length and 1.6mm in width. Designed for data line protection, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated LC topology for effective electromagnetic interference suppression
• Compact 1206 surface-mount form factor suitable for space-constrained designs
• Top-side adjustment capability for precise circuit tuning

Applications

• Data line filtering in high-frequency circuits
• EMI suppression in portable electronic devices
• Signal integrity protection in communication modules

Procurement Notes

Verify the specific suffix W3 against official datasheets to confirm package and tolerance specifications. Confirm availability status as components may be subject to end-of-life notices. Ensure compatibility with automated pick-and-place equipment regarding the 1206 footprint dimensions.

Selection Notes

Select this component when a compact LC filter is required for data lines with a maximum current of 200mA. The 130pF capacitance value is critical for specific cutoff frequencies. Evaluate thermal performance requirements against the -40°C to +85°C operating range before integration into the final assembly.

Part Context

This part belongs to the KNF series of EMI/RFI filters from KYOCERA AVX. These components are engineered to provide noise reduction in sensitive electronic applications. The series offers various capacitance values and package sizes to accommodate different circuit design constraints and filtering requirements.

Replacement Considerations

Consult official substitution guides for compatible parts. Verify that alternative components match the 1206 footprint, 130pF capacitance, and 200mA current rating to ensure functional equivalence without redesigning the PCB layout.
