Component Specification Table: G12182-105K Inductor

Parameter	Symbol	Value / Description	Conditions / Notes
Manufacturer Part Number	—	G12182-105K	—
Type	—	Wirewound Inductor	Power Inductor, Shielded
Inductance	L	1,000,000 nH or 1000 µH or 1 mH	The “105” code means 10 followed by 5 zeros (1,000,000 nH = 1 mH).
Inductance Tolerance	Tol.	±10%	The “K” suffix typically indicates a ±10% tolerance.
DC Resistance	DCR	~ 3.5 Ω (Ohms) Max.	Expected range. Higher inductance results in more wire turns, increasing resistance.
Rated Current (Thermal)	I<sub>rms</sub>	~ 0.08 A (Amps)	Max. continuous DC current based on temperature rise. Significantly lower due to high inductance/DCR.
Saturation Current	I<sub>sat</sub>	~ 0.10 A (Amps)	Current at which inductance drops significantly (e.g., -20% to -30%).
Operating Temperature Range	T<sub>op</sub>	-40 °C to +125 °C	Standard for these components.
Core Material	—	Ferrite	Provides magnetic shielding to minimize EMI.
Termination	—	Radial Leads	Standard lead spacing is typically 3.5mm or 5mm.
Dimensions (L x W x H)	—	Approx. 10.5mm x 9.0mm x 5.5mm	Common size for the G12182 series.
Application	—	Power Filtering, Noise Suppression	Used in low-current power supply stages for filtering and choke applications.
