Description:
These are **NOT diodes**—the multiple color bands and molded body indicate **axial molded inductors (RF chokes)**. Your band set **Black–Green–Brown–Yellow** most commonly decodes as an inductance value of approximately **50µH** (05 × 10 = 50µH) with a **tolerance band** (yellow commonly used as a tolerance code on molded inductors). Great for EMI/RFI suppression, signal/power filtering, and vintage radio/telecom/industrial board repairs. Lot includes 10 pieces as pictured.

Modern uses:
- EMI/RFI filtering and noise suppression on power rails
- Small LC filters, chokes in analog/signal paths
- Ripple reduction / decoupling networks (design-dependent)
- Repairs for vintage radios, test gear, telecom, industrial controls
- Prototyping inductive filters (verify value)

Compatibility note:
Inductors are application-specific—confirm **inductance (µH)**, **DC resistance (DCR)**, and **current rating** before use. Color codes can vary by manufacturer/series; if critical, **measure with an LCR meter** to confirm the ~50µH value and tolerance. Also verify physical size/lead spacing fit your PCB.
