15 µH wirewound inductor in 1210 footprint — NRND lifecycle
The Taiyo Yuden LBC3225T150KR is a 15 µH wirewound inductor from the LB, C Type series, housed in a 1210 (3225 Metric) surface-mount package. It is rated for 420 mA continuous current with a DC resistance of 195 mOhm, making it suitable for power-supply filtering and DC-DC converter output stages where moderate inductance and current are needed. Sourcing is confirmed per RFQ through independent distribution channels.
The 15 µH inductance is tested at 100 kHz and holds ±10% tolerance. The self-resonant frequency is 20 MHz, which sets the upper frequency limit for effective filtering — above this, the inductor behaves capacitively. Unshielded construction means the magnetic field is not contained within a ferrite shield. In dense PCB layouts, adjacent traces carrying high-frequency signals may couple noise through the inductor's stray field — placement away from sensitive analog or RF paths is advised. This is a standard-size power inductor package, compatible with reflow soldering profiles for lead-free assembly. The wirewound construction delivers higher Q and better current saturation characteristics than multilayer ferrite alternatives at this inductance value.
