The SQ series components stand out with an O-type SQ ferrite core design—delivering a compact footprint paired with low leakage flux. Their low stray capacitance enables broad-frequency noise attenuation, while the single-layer winding eliminates interlayer short-circuit risks. These parts also offer strong normal-mode noise suppression, cut winding time by up to 90%, and achieve high inductance via proprietary ferrite mixing and sintering technology.
Ideal for diverse scenarios, they’re widely used in switching power supplies, LED drivers, industrial automation equipment, communication devices, household appliances, and audio/medical equipment.
For flexibility, the series offers configurable options: choose between bulk or Tape & Reel packaging, customize inductance, wire gauge, and winding setups, select alternative ferrite materials for tailored performance, or request SMD versions as needed.
Technical specifications include a 250V AC/DC rated voltage, -40°C to +120°C operating temperature, and line-to-line withstanding voltage (AC 2000V for 60 sec or AC 2400V for 1–2 sec). They also meet ≥100 MΩ insulation resistance (at DC 500V) and maintain ≤40°C temperature rise at rated current.
