Dip / Radial power inductor (non shielded) RCB / RDR series
Cost-Effective Dip Power Inductor, THT Radial Choke (Unshielded), Axial Alternative
Coilmaster offers high-performance, cost-effective unshielded radial power inductors (Pin-Type Chokes, Vertical Mount). These robust components are optimized for minimal losses, delivering High Q, High SRF, and Low DCR across a wide inductance range (e.g., 0608 to 2825). They serve as the ideal low-cost alternative to shielded or SMD types for filtering applications where low flux requirements exist and budget is critical.
Why choose unshielded RDR/RCB? These are ideal drop-in solutions for VDR, LED Drivers, and Battery Chargers where simplicity and cost are prioritized over magnetic shielding. Best utilized in non-critical filtering stages or non-switching circuits where low EMI risk and low ripple current demands exist. Custom winding and pin layouts are available.
