MEM2012SC470

Overview

The MEM2012SC470 is a multilayer chip EMC filter manufactured by TDK Corporation. It features a monolithic structure and a closed magnetic circuit design, ensuring high reliability and enabling high-density mounting. The component operates with a rated voltage of 12V and utilizes an 0805 (2012 Metric) package with a 6 PC Pad configuration for surface mount applications. It functions as a third-order low-pass LC (T-Type) EMI filter with one channel. The capacitance value is specified at 47pF, and the device supports a current rating of 1A. It is compliant with RoHS3 standards.

Feature Summary

• Monolithic structure ensures high reliability
• Closed magnetic circuit enables high-density mounting
• Third-order low-pass LC (T-Type) filtering architecture

Applications

• EMI/RFI suppression in electronic circuits
• High-density surface mount assembly
• Low-pass filtering for signal integrity

Procurement Notes

Verify the specific ordering suffix to confirm exact packaging quantities and lead times, as these details are not provided in the general datasheet summary. Ensure compliance with RoHS3 requirements matches project specifications. Confirm the 0805 footprint compatibility with your PCB layout before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a compact, third-order low-pass filter is required for EMI suppression in space-constrained designs. The 12V rated voltage and 1A current handling capability suit low-power signal lines. The 47pF capacitance value defines the cutoff characteristics. Consider the 0805 package size for standard surface mount processes. Verify thermal performance if operating near maximum ratings.

Part Context

This component belongs to the TDK MEM series of multilayer chip EMC filters. The series is characterized by its use of closed magnetic circuit structures to minimize external interference and enhance performance. These filters are designed for modern electronics requiring effective noise suppression in small form factors. The MEM series represents TDK's approach to integrating passive filtering elements into reliable, mass-producible ceramic packages.

Replacement Considerations

Publicly confirmed substitute part numbers include MEM2012TC470T001. Verify electrical parameters such as capacitance, voltage rating, and package dimensions before substitution. Ensure the alternative maintains the same third-order low-pass LC topology and RoHS3 compliance status.
