Murata’s BNX Series Block Style EMI Filter

Excellent Noise Suppression On DC Powerlines The Murata Electronics BNX series of DC power line EMI filters offers wide frequency noise suppression in a compact, low profile SMD design suitable for industrial and commercial applications. Utilizing Murata’s unique ceramic and ferrite materials packaging technology, the BNX block style EMI filter is comprised of a network of capacitors and ferrite beads which offer significant Insertion Loss (I.L.) across a wide frequency range from 1 MHz to 1 GHz . The rated voltage is 50 VDC with up to a 15 A current rating over a temperature range up to -40 C° to +125 C°. Additional features of the BNX series block style EMI filter include:

Features:   • Broad noise suppression across a wide frequency range in a single package   • High insertion loss characteristic over a wide frequency range from 1 MHz to     1 GHz: 40dB minimum (BNX012)   • Large rated current:15A (BNX012)   • Low DC resistance: 0.43m ohm typical (BNX022)   • Effective for impulse noise such as electrostatic discharge or spike   • Unique construction ensures high performance and high reliability   • Low profile height: 8.0mm (BNX-012)   • RoHS compliant

Applications:   • Flat Panel Display (PDP/ LCD-TV)   • Digital AV equipment   • PC peripheral equipment   • Industrial equipment   • Measurement equipment   • Power Supplies
