CDRH124 SMD PWR Fixed Inductors 22uH 2.9A ±20%
The CDRH124 is an elegantly compact surface-mount power inductor built around a ferrite drum core and finished with magnetic shielding to reduce EMI. Its low-profile, square footprint and molded exterior give it a robust, production-friendly presence on modern PCBs while helping keep stray fields contained and predictable during dense board layouts.
Designed for continuous operation across a wide ambient span, the component tolerates elevated self-heating and broad temperature swings without compromising winding integrity. The manufacturer calls out moisture-sensitivity level 1 and a conservative solder-reflow tolerance, making the part compatible with standard surface-mount assembly flows and minimizing handling constraints during manufacturing.
The CDRH124 is delivered in carrier tape and reel for automated placement and is documented with clear mechanical drawings, land-pattern recommendations and thermal/saturation graphs. The combination of concise datasheet guidance, tape-and-reel packaging and predictable electrical behaviour simplifies design verification and high-volume assembly.
Features:
- Ferrite drum-core construction with magnetic shielding.
- Compact SMD package optimized for automated placement.
- Low DC-resistance design for efficient current handling.
- Moisture Sensitivity Level 1 (MSL1) for straightforward assembly.
- Supplied in tape-and-reel to support production pick-and-place.
