BNX002-01

Overview

The Murata BNX002-01 is a block-type EMI suppression filter designed for through-hole mounting. It integrates feed-through capacitors, monolithic capacitors, and bead inductors to form a fifth-order low-pass LC network. The component operates within a voltage range of 50 VDC and supports a maximum DC current of 10 A. It provides an insertion loss of 40 dB across the 0.5 MHz to 1 GHz frequency spectrum. Physical dimensions are 12.0 mm x 11.0 mm x 13.0 mm with a 2.5 mm lead pitch.

Feature Summary

• Integrates feed-through capacitors, monolithic capacitors, and bead inductors into a single block structure
• Provides high insertion loss for effective electromagnetic interference suppression
• Offers protection against electrostatic discharge and spike noise events

Applications

• DC power supply circuits
• Display equipment
• Digital AV devices
• PC peripherals
• Industrial equipment

Procurement Notes

Verify the specific suffix code on the datasheet to confirm exact pin configuration and termination type. Ensure the selected variant matches the required operating temperature range and current rating for the target application. Cross-reference the manufacturer part number with official Murata documentation to avoid counterfeit components.

Selection Notes

Select this component when high current handling up to 10 A is required alongside significant EMI attenuation. The block-type construction allows for robust through-hole installation in space-constrained environments. Consider the 50 VDC rating and 40 dB insertion loss characteristics when designing filters for sensitive digital or analog power lines.

Part Context

This component belongs to the Murata BNX series of block-type EMIFIL products. These filters are engineered for general-purpose EMI/RFI suppression in electronic systems. The series utilizes combined LC filtering techniques to achieve broad-spectrum noise reduction while maintaining structural integrity under high current loads.

Replacement Considerations

Consult official Murata documentation for verified substitute part numbers within the BNX series. Ensure any replacement maintains identical electrical ratings, physical dimensions, and mounting specifications.
