CM453232-180KL

Fixed Inductors Overview

The CM453232-180KL is a fixed power inductor from Bourns Inc., designed for surface-mount technology (SMT) applications. It features an unshielded drum core with wirewound construction, housed in a standard 1812 (4532 metric) package measuring 4.5 mm x 3.2 mm x 3.2 mm. The component provides an inductance of 18 µH with a tolerance of ±10%. It supports a maximum DC current of 190 mA and exhibits a maximum DC resistance of 2.8 Ohms. The device operates within a temperature range of -40°C to +100°C and utilizes ferrite core material.

Fixed Inductors Procurement Notes

Verify the exact part number against official Bourns documentation to confirm the unshielded configuration and electrical parameters. Ensure that the 1812 package dimensions align with the PCB layout constraints. Confirm that the operating temperature range meets the environmental requirements of the target application. Cross-reference the datasheet for any recent updates regarding moisture sensitivity or soldering heat resistance specifications.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is required to minimize magnetic coupling issues in adjacent circuitry. The 18 µH value and 190 mA current rating suit low-power signal conditioning tasks. Consider the physical size and lead-free compliance if RoHS standards are mandatory. Evaluate the self-resonant frequency characteristics against the operational frequency of the circuit to ensure effective performance.

Fixed Inductors Part Context

This component belongs to the CM453232 series of chip inductors manufactured by Bourns. The series includes various inductance values within the same 1812 package form factor. These inductors are characterized by their encapsulated construction and suitability for automated surface-mount assembly processes. The series is widely used in consumer electronics and industrial equipment where space efficiency is critical.

Fixed Inductors Replacement Considerations

Compatible substitutes include other 18 µH unshielded wirewound inductors in the 1812 package from manufacturers such as Coilcraft or TDK. Verify that alternative parts match the 190 mA current rating and 2.8 Ohm resistance limits. Ensure the replacement maintains the same temperature range and mounting compatibility.
