Lead-Free Common Mode Choke for LED Lighting Equipment

Product Overview

The UU16 Common Mode Line Choke is a high-performance miniaturized electromagnetic component engineered by INF, a professional manufacturer of power electronic components, optimized for B2B power electronics and telecommunication equipment applications. As a ferrite UU core common mode choke with F-class enamelled copper wire winding, this component integrates high reliability and excellent high saturation DC current performance, becoming a core selection for AC power supplies, DC-DC converters and high-end telecom devices. Adopting a halogen-free and lead-free eco-friendly design, this RoHS compliant common mode choke for AC power supplies features strong frequency adaptability to meet the diverse working frequency needs of industrial scenarios. With a compact weight of only 9.50 g, it achieves up to 70 dB of common-mode noise attenuation with just ~1% stray inductance, realizing efficient symmetric EMI suppression while ensuring outstanding winding insulation isolation. It holds a Moisture Sensitivity Level (MSL) of 1 and complies with UL 94 V-0 flammability standard, operating stably in complex industrial environments and meeting the strict electromagnetic compatibility (EMC) requirements of professional electronic equipment for B-end users.

Core Advantages

Superior EMI Suppression Capability

As a high attenuation common mode line choke, the UU16 series achieves up to 70 dB of common-mode noise attenuation with an ultra-low ~1% stray inductance, enabling precise and symmetric interference suppression for power transmission lines. Select models are equipped with a high Q factor (>100) and a wide self-resonant frequency, which can effectively block high-frequency common-mode noise while ensuring unimpeded DC and low-frequency AC signals, fully meeting the EMC requirements of high-end electronic devices.

Robust Electrical and Structural Reliability

The winding dielectric strength of the UU16 Common Mode Line Choke exceeds 1500 V, and the pin strength is not less than 1.0 kg, effectively avoiding mechanical damage and electrical failure during long-term industrial operation and assembly. The ferrite UU core structure ensures excellent high saturation DC current performance, and all electrical parameters remain stable in the standard 25℃ environment, meeting the long-term reliability requirements of B-end industrial equipment.

High Environmental Adaptability

This common mode choke has a standard operating temperature range of -25℃ to +85℃ (including temperature rise) and an extended operating range of -40℃ to +125℃, adapting to harsh industrial temperature conditions such as high-temperature workshops and low-temperature outdoor equipment. Compliant with climatic category 40/125/21 and MSL 1 rating, it has strong resistance to moisture and thermal aging, suitable for high-humidity and high-temperature industrial application scenarios.

High Compatibility with Industrial Production Processes

The UU16 Common Mode Line Choke is fully compatible with automated pick-and-place processes and features superior solderability, which can be seamlessly integrated into the mass production lines of electronic equipment. This design effectively improves the production efficiency of B-end manufacturers and reduces the assembly and production costs of electronic products.
