Panasonic 1040 Shielded Surface Mount Inductor with Metal Composite Core 33 μH ±20% 3.9 A IDC ETQP4M

Panasonic ETQP4M 1040 Shielded Surface Mount Inductor features a metal composite core technology providing reliable power choke performance with 33 μH inductance and ±20% tolerance. Designed for high current handling up to 3.9 A IDC and low DC resistance, this inductor is suitable for automotive and industrial environments.

The low profile 1040 package measures 10.7 mm in length, 10 mm in depth, and 4 mm in height, making it ideal for compact surface mount applications. The metal composite core offers excellent heat resistance at temperatures up to 155°C, ensuring stability across a wide temperature range down to -55°C.

These shielded inductors minimize electromagnetic interference (EMI) and maintain inductance stability over temperature variations. Their robust construction meets AEC-Q200 automotive standards and provides high vibration resistance to withstand harsh operational conditions.

Typical applications for the ETQP4M series include DC/DC buck and boost converters, noise filtering in drive circuitry, and other automotive power management systems requiring high bias current capability and efficient power conversion.

Low profile surface mount design promotes compact PCB integration. Metal composite core improves heat tolerance and bias current. Shielded design ensures reduced EMI and stable inductance. AEC-Q200 qualification certifies automotive industry compliance.

Low DC resistance reduces power losses, improving efficiency. Wide operating temperature from -55°C to 155°C for demanding environments. Produces low audible (buzz) noise for quieter operation. High vibration resistance protects performance under mechanical stress.

This Panasonic ETQP4M inductor is molded and RoHS compliant, originating from Japan. It is a reliable passive component solution for electronics, power management, automotive, and industrial applications.
