Product Overview

The DLW43MH201XK2L is a wire wound chip common mode choke coil designed for automotive electronics by Murata, compliant with AEC-Q200 standards. It offers excellent electromagnetic interference (EMI) suppression, ideal for harsh vehicle environments. With a high-reliability design, it operates stably across a wide temperature range, enhancing circuit signal integrity and serving as the perfect choice for power and signal line filtering in automotive electronic systems.

Key Features

• Wide Temperature Operation：Supports an operating temperature range of -40°C to +105°C, adapting to high-temperature and extreme scenarios like vehicle engine compartments.
• High Common Mode Inductance：200μH common mode inductance (tolerance -25%~+50%) ensures efficient EMI suppression at 0.1MHz.
• Low DC Resistance & High Rated Current：Maximum DC resistance of 4.5Ω and a rated current of 110mA minimize energy loss and support high-current circuits.
• Superior ESD Protection：ESD Rank 6 (25kV) effectively resists electrostatic interference, enhancing circuit stability.
• AEC-Q200 Compliance：Passes rigorous reliability tests (high-temperature exposure, thermal cycling, biased humidity, etc.), meeting the high-reliability demands of automotive electronics.
