## Description

The Bourns JW Miller 2124-H-RC is a high-current toroidal inductor from the 2100 series, engineered for demanding power conversion and electromagnetic interference (EMI) filtering applications. This component provides a nominal inductance of 1 mH with a tolerance of ±15% at 1 kHz. Designed for robust electrical performance, it features a maximum DC resistance (DCR) of 0.4 Ω and supports a continuous RMS current (Irms) of 1.3 A. The current rating is defined by the thermal limit required to induce a maximum temperature rise of 30 °C above ambient.

Constructed for reliability in industrial environments, the 2124-H-RC utilizes a toroidal core geometry that minimizes magnetic radiation and core losses. The device is rated for an operating temperature range of -55 °C to +105 °C, ensuring stability across diverse thermal profiles. This specific part number is configured for horizontal mounting, facilitating integration into through-hole PCB assemblies. The leads are tinned to within 0.062 inches of the mounting plane, supporting standard soldering processes. This inductor is fully RoHS compliant, meeting environmental standards for modern electronic hardware design.
