Procurement Notes

Verify the specific suffix 'S' against official TDK documentation to confirm it denotes the standard unshielded variant, as some series use different letters for shielding or tolerance variations. Ensure the ordering part number matches the exact impedance and current ratings required for the target circuit design. Cross-reference the manufacturer's latest datasheet to confirm compliance with RoHS directives and lead-free soldering compatibility before finalizing procurement.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for signal lines carrying up to 500 mA DC. The 0603 package size is suitable for space-constrained PCB layouts. Consider the 25% impedance tolerance and 250 mOhms DC resistance when calculating signal loss and power dissipation. Ensure the operating environment stays within the specified -55°C to +125°C temperature range for reliable performance.
