1 mH wirewound, 15 mA — what the ratings mean for your BOM
The Taiyo Yuden LBC2518T102K is a 1 mH unshielded wirewound inductor in the LB series, packaged in the 1007 (2518 Metric) surface-mount footprint. The 15 mA current rating is the continuous DC limit at the rated ambient — exceeding it saturates the core and collapses the inductance, so the BOM engineer must budget the full-load current of the downstream circuit against this ceiling. Unshielded construction means the magnetic field radiates into the surrounding board area — adjacent traces carrying sensitive analog signals or high-speed clocks need keep-out spacing to avoid coupling. The ±10% tolerance is standard for power filtering but may require tighter binning for resonant tank circuits.
Obsolete — sourcing reality for the procurement desk
Taiyo Yuden lists the LBC2518T102K as obsolete. Sourcing is through independent distribution channels — each lot is confirmed for date-code authenticity and physical condition at RFQ.
Package and temperature envelope
Operating temperature spans -25°C to 105°C, which covers indoor and most industrial ambient ranges but does not reach full automotive under-hood temperatures.
