100 µH wirewound inductor for low-current filtering and DC-DC smoothing
The Taiyo Yuden LBC2518T101MV is a wirewound inductor in the LB, C Type series, offering 100 µH inductance with ±20% tolerance in an unshielded 1007 (2518 Metric) surface-mount package. Rated for 125 mA continuous current with a maximum DC resistance of 4.81 Ohm, this part is suited for low-power filtering, DC-DC converter output smoothing, and signal conditioning circuits where board space is constrained to a 2.50 mm × 1.80 mm footprint.
Self-resonant frequency and usable bandwidth
A self-resonant frequency of 9 MHz (tested at 796 kHz) defines the upper limit of the inductor's inductive behavior — above this frequency, parasitic capacitance dominates and the component behaves capacitively. For a 100 µH value, a 9 MHz SRF is typical of a wirewound construction that balances core losses and winding capacitance; the part remains inductive well into the low-MHz range, covering common switching frequencies for small buck converters and EMI filter networks.
NRND status — plan for a replacement in new designs
Taiyo Yuden lists this inductor as Not Recommended for New Designs (NRND) — existing BOM lines should be qualified for a successor part before the component enters end-of-life.
