CM453232-221KL is a surface-mount chip inductor from the CM45 Series designed for automatic surface mounting in compact electronic assemblies. This inductor features a 220 µH inductance value with ±10% standard tolerance, a ferrite core with copper wire coil, and an epoxy resin enclosure with tin terminals. It operates across a wide temperature range from -40°C to +125°C, with a maximum ambient temperature of 100°C and temperature rise of 20°C maximum, ensuring stable performance in demanding environments. The device exhibits high resistance to heat, humidity, mechanical shock, and pressure, making it suitable for power supply filtering, signal coupling, and impedance matching in RF and mixed-signal circuits.
