The SQ1212 is a high performance, vertical mount common mode current choke specifically engineered for applications demanding maximum space savings without compromising EMI/RFI filtering effectiveness. Its ultra-thin frame and compact vertical orientation make it the ideal solution for densely packed PCBs in modern electronics.

Features:

Vertical Ultra-Thin Design:

Space Optimized: Mounts vertically onto the PCB, utilizing minimal board surface area – perfect for tight layouts in power supplies, LED drivers, adapters, and IoT devices.

Profile: Significantly lower footprint compared to traditional horizontal chokes.

Effective Common Mode Noise Suppression:

Targets and attenuates unwanted high-frequency electromagnetic interference (EMI) and radio-frequency interference (RFI) traveling in-phase (common mode) along power or signal lines.

Crucial for meeting EMC compliance standards (FCC, CE, CISPR, etc.) and preventing circuit malfunction.

High Current Handling:

sq1212 common mode current chokes are designed to handle typical line currents found in compact power applications.

Wide Operating Frequency Range:

Effective filtering across a broad spectrum, ideal for suppressing noise generated by switching power supplies and digital circuits.

Robust Construction:

Features a durable vertical frame housing that protects the windings and ensures mechanical stability during assembly and operation.

Surface Mount (SMT) Compatibility:

sq1212 common mode current chokes are designed for easy integration into automated SMT assembly processes, reducing manufacturing costs and time.

Electrical characteristics: (at 25℃)

PCB board aperture Ø1.4mm
