Advanced Analysis of the VCM-EE1-203-W1 Rev 4.0 Common Mode Inductor: Key Specifications and EMI Suppression

Common mode filters (CMFs), also known as common mode chokes (CMCs), are passive electronic components designed to suppress electromagnetic interference (EMI) by attenuating common mode noise in electronic circuits. These filters are essential in modern electronics where high-frequency noise can degrade signal integrity, cause malfunctions, or fail regulatory compliance (e.g., FCC, CE, CISPR). This product features precise physical dimensions with specified tolerances to ensure quality and compatibility. Key measurements include:

• Length: 5.0±0.5

• Width: 6.8±0.5

• Height: 3.8±1.5

Additional specifications:

• VIIP Metal Wall : A critical component ensuring durability.

• Maximum Thickness/Depth : 9.5 Max (with a tight tolerance of 9.5±0.2 in one section).

• Other Limits : 10.0 Max (unspecified dimension).

The design includes numerical markers (4, 3, 2), likely indicating assembly steps, component tiers, or reference points.

Note : All dimensions are in the same unit (assumed to be millimeters, unless stated otherwise). Tolerances and max values highlight the product’s focus on structural precision.
