component
BLM21BD222TZ1D
Public Made by Adomby adom
Murata Electronics Ferrite Beads, 0805. Unpolarised two-terminal part: the datasheet prints no pin numbers, so pins 1 and 2 follow the library convention, KiCad symbol/footprint/3D.

Electrical characteristics
Limits as printed in the datasheet (page.json metadata.characteristics carries them as data).
| Parameter | Symbol | Min | Typ | Max | Unit | Conditions | Page |
|---|---|---|---|---|---|---|---|
| Impedance tolerance (at 100MHz) | -25 | 25 | % | At 100MHz; printed as ±25% for BLM21BD222TZ1D in the rating table | 2 | ||
| Impedance change after AEC-Q200 stress tests (at 100MHz) | -30 | 30 | % | At 100MHz, after AEC-Q200 tests (Table A/B); printed as within ±30% (±50% applies only to BLM21SN, not this part) | 3 | ||
| DC resistance (max, first value column) | 0.6 | Ω | Standard testing conditions (*1) | 2 | |||
| DC resistance (max, second value column) | 0.7 | Ω | Second DC resistance value column as printed; column header unclear in text extraction | 2 | |||
| Rated current | 200 | mA | Row is not marked *2, so no temperature derating footnote is printed for this part | 2 | |||
| Operating temperature | -55 | 125 | °C | Operating temperature range as printed for the chip ferrite bead series | 2 | ||
| Storage temperature | -55 | 125 | °C | Storage temperature as printed in the bullet list; this is not classified as an absolute maximum in the datasheet | 2 | ||
| Impedance (nominal, at 100MHz) | 2200 | Ω | At 100MHz, standard testing conditions (*1); tolerance ±25% listed separately | 2 |
