The KLF0735 Series is a wire-wound, magnetically shielded SMD Common Mode Choke (line filter). It is built with a ferrite drum core construction and is designed to provide high common mode impedance for filtering noise in power lines and signal lines.
This series is engineered for high reliability, featuring a robust 7.3 mm × 5.3 mm footprint and H-class enamelled copper wire. With a high rated current of 4.0A and 700Ω impedance at 100MHz, the KLF0735 is an excellent solution for suppressing EMI in demanding applications. Its shielded design and features make it a primary component for signal integrity. The KLF0735 is available for inductors for sale, offering robust performance for power filtering.

Notes:
Test Conditions: All test data is referenced to 25°C ambient.
Operating Temperature Range: -40°C to +125°C (ambient plus self-temperature rise).
Irms (Rated Current): DC current (A) that will cause an approximate ΔT of 40°C (reference ambient temperature is 25°C).
Temperature Limit: The part temperature (ambient + temp rise) should not exceed 125°C under worst-case operating conditions.
