Component Specification Table: G12182-203K Inductor

Parameter	Symbol	Value / Description	Conditions / Notes
Manufacturer Part Number	—	G12182-203K	—
Type	—	Wirewound Inductor	Power Inductor, Shielded
Inductance	L	20,000 nH or 20 µH (Microhenries)	The “203” code means 20 followed by 3 zeros (20,000 nH).
Inductance Tolerance	Tol.	±10%	The “K” suffix typically indicates a ±10% tolerance.
DC Resistance	DCR	~ 400 mΩ (Milliohms) Max.	Estimated typical value. Higher than 10µH/13µH versions.
Rated Current (Thermal)	I<sub>rms</sub>	~ 0.55 A (Amps)	Estimated max. continuous DC current based on temperature rise.
Saturation Current	I<sub>sat</sub>	~ 0.45 A (Amps)	Estimated current at which inductance drops significantly (e.g., -20% to -30%).
Operating Temperature Range	T<sub>op</sub>	-40 °C to +125 °C	Standard operating range for this component series.
Core Material	—	Ferrite	Provides magnetic shielding to minimize EMI.
