CKCS4030-221M Pinout

Package: SMD 4030 (4.0mm × 3.0mm × 4.0mm) — Two-terminal inductor

Notes

• CKCS4030-221M is a 220 μH ±20% inductor with SMD 4030 package.
• This is a two-terminal passive component (inductor); there are no logic pins, power pins, or ground pins in the traditional sense.
• Both terminals are bidirectional signal/power connections.
• Electrical characteristics for CKCS4030-221M:
  • Inductance: 220 μH (±20%)
  • DCR (Max): 3250 mΩ
  • DCR (Typ): 2500 mΩ
  • Isat (Max): 0.4 A
  • Irms (Max): 0.35 A
  • Test conditions: 100 kHz / 1V
  • Absolute maximum voltage: DC 50V
• Operating temperature: −40 °C to +125 °C
• The component uses ferrite cores with magnetic-resin shielded construction.
• No pin diagram with numbered terminals was provided in the source material. Pin numbering (1, 2) is conventional for a two-terminal SMD inductor and should be verified against the physical component or manufacturer's assembly drawing.
