Custom Toroidal Inductors: Balanced Performance for Industrial Power

Sub-headline:

The versatile workhorse for noise suppression. Our Toroidal Inductor series (RPI Model) combines Sendust Core technology with a robust vertical structure, delivering the optimal balance of inductance, current handling, and cost for industrial power supplies.

Key Highlights:

Optimized Filtering: Delivers 330µH of inductance, specifically tuned for output ripple suppression in switching regulators.

Soft Saturation: Utilizes Sendust (KSN) magnetic cores to maintain inductance stability even under transient load conditions, preventing circuit instability.

Compact Integration: Features a Vertical Base Mount to minimize PCB footprint while ensuring mechanical vibration resistance.

Reference Case Study: Model RPI2714-330K

Note: The specifications below are from our production model RPI2714-330K. This demonstrates our manufacturing capability for Standard Toroidal Inductors.

Parameter	Specification (Reference Only)	Customization Range
Model P/N	RPI2714-330K	Custom P/N assignment available
Category	Toroidal Inductor	Output Choke / Buck Inductor
Inductance (L)	330 µH ± 10% (@1kHz)	10µH - 10mH (Optimized for Application)
DCR (Resistance)	130 mΩ Max	Minimized by wire gauge
Core Material	KSN90060A (Sendust)	Sendust / Iron Powder / High Flux
Structure	Vertical Base (2-Pin)	Horizontal / Flying Leads
Wire Specs	0.50mm UEW (Ref)	TIW / Multi-strand wire

Engineer's Insight: The RPI2714 utilizes a KSN90060A Sendust core. With 77 turns of 0.5mm wire, it achieves 330uH inductance with a DCR of just 130mΩ. This mid-range specification makes it an excellent all-rounder for 24V/48V industrial DC-DC converters.

Tailor This Inductor to Your Needs

We customize Toroidal Inductors to match your exact power topology.

Material & Winding Optimization

● Core Selection: We select from Sendust, Iron Powder, or High Flux cores based on your switching frequency. Sendust is the preferred choice for applications requiring low noise and high efficiency.

● Winding Tech: For higher currents, we can use Multi-strand Winding to reduce skin effect, or increase wire gauge to lower DCR.

Mechanical Customization

● Mounting: Available in Vertical (saving board space) or Horizontal (low profile) configurations.

● Stabilization: We apply Varnish Impregnation or Silicone Fixing to ensure the inductor survives drop tests and rigorous industrial vibration standards.
