Axial Lead Power Inductors (EOL Replacement, Horizontal / Vertical Packing)
Axial leaded power inductors are THT wire-wound components used for low-loss energy storage, current filtering, and surge handling in switching regulators and communication equipment. Constructed on ferrite drum cores and protected by epoxy, they deliver high SRF, excellent Q performance, and long service life. Coilmaster provides stable mass production and direct cross-reference replacements for EOL models from major brands such as TDK.
Available in both horizontal taped (water-flat type) and pre-formed vertical taped packaging, our axial inductors are compatible with automatic insertion/AI machines and selective wave soldering. This ensures high assembly efficiency and reliable sourcing for discontinued TDK series.
Two Packaging Options for Flexible Production
1: Flat Taping (Water Bottle Type) → Cost-friendly, allows customers to bend the lead angle themselves for custom installation.
2: Vertical Pre-Formed Taping (Stand-Up / K-bent) → Fully formed leads, AI-ready, suitable for high-throughput production lines, reducing labor cost and assembly time.
