Product Description
Panasonic ETQP4M Surface Mount Inductor is a low profile power choke coil featuring a 22 μH inductance with integral construction built around a metal composite core. This inductor is designed to handle a high DC current of up to 4.1 A, making it ideal for demanding automotive and industrial electronic circuits.
Its 0840 surface mount package allows compact PCB layout without compromising electrical performance. The use of metal composite core technology confers excellent heat resistance with operational temperatures ranging from -55°C to 155°C, and ensures mechanical robustness against vibration and thermal stresses commonly encountered in harsh environments.
With a tolerance of ±20 %, inductance stability is maintained over varying temperature ranges, supported by a low DC resistance of 78.4 mΩ which aids in minimizing energy losses and improving efficiency. This coil complies with the AEC-Q200 automotive standard, ensuring high reliability and longevity for automotive power supply filters and noise suppression applications.
The integral construction design results in very low audible noise, enhancing user experience in noise-sensitive environments. Panasonic ETQP4M series is widely applied in DC/DC buck and boost converters, as noise filters in drive circuitry, and in numerous other power management systems within automotive and industrial electronic modules.
The product comes packaged on embossed carrier tape for reliable automated handling during assembly and is manufactured in Japan, reflecting premium quality and stringent manufacturing standards.
