Product Description
Compact SMD Common Mode Chokes for Power Supply Noise Suppression
Engineered for modern power electronics, the SQS1212A Series represents a line of high-performance SMD Inductors designed to effectively suppress electromagnetic interference (EMI). These Low DCR Chokes utilize a square core construction and high-permeability material to deliver high impedance at low frequencies with minimal DC power loss. Their compact SMD flat profile and superior attenuation characteristics make them an ideal, cost-effective solution for enhancing EMC performance in space-constrained applications.
Key Features
- Space-Efficient & Reliable: Compact SMD footprint with a square core design minimizes board space usage and reduces magnetic leakage.
- Superior EMI Suppression: High-permeability material combined with low stray capacitance ensures high impedance at low frequencies and provides excellent attenuation of common-mode noise.
- High Current Capability: The Low DCR Choke design minimizes voltage drop and power loss, supporting high rated currents up to 3.0A for robust power handling.
- Safety & Compliance: Construction features materials compliant with UL94V-0 flammability rating and offers high insulation resistance, meeting international safety standards. The series is also RoHS and REACH compliant.
- Automated Production: Manufactured with automated processes for high consistency, reliability, and cost-effectiveness.
