inductors hero

Voltage step-up coils

- Large inductance values; small and low profile
- Magnetic structure and narrow wire diameter using high speed winding technology to achieve 50mH
- High reliability (drop impact resistance)

Features

1. High inductance and space saving. 

  • Small and low profile (1.2mm max./1.4mm max.).
  • Short terminals (4.0mm max.~ 5.5mm max.).

2. High inductance ≤50mH. 

  • Optimized magnetic structure and winding technology.

3. High reliability with fully automated processes (high shock resistance).

  • Thin insert-molded terminal structure is robust against the wire-cut problem.

Structure

inductor consumer voltage-step-up-coil structure
  1. Ferrite core
  2. User terminal
  3. Maker terminal
  4. Coil
  5. Terminal board
  6. Ring

Element Technology

1. Winding and junction technology

  • High speed winding technology of extra-thin wire
  • High speed solder junction technology by YAG

2. Continuous hoop production by high speed winding machine

3. Wide range of inductance values available due to the combination of extra-thin wire coil forming and magnetic ring construction
