Procurement Notes

Verify the specific suffix against official TDK documentation, as variations may exist. Confirm availability status, as some listings indicate discontinued or limited stock. Ensure compatibility with automated pick-and-place equipment regarding the tape and reel packaging format. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and technical specifications before procurement.

Selection Notes

Select this component when filtering common mode interference on differential or dual signal lines requiring low insertion loss and moderate current handling. The 270 Ohm impedance at 100 MHz targets high-frequency noise suppression. Ensure the operating environment stays within the specified -25°C to 85°C range. Verify that the 300 mA current rating meets the circuit's peak requirements without causing excessive saturation or thermal issues.

Part Context

This component belongs to TDK's ACM series of common mode chokes, which are engineered for signal integrity in compact electronic systems. The 3225 package size allows for dense PCB layouts while maintaining adequate electrical performance for noise mitigation. These chokes are widely utilized in digital interfaces and communication circuits where electromagnetic interference must be minimized.
