China Panasonic Surface mount power inductor ETQ-P8M/AM*J Series ETQPAMR68JFW Manufacturers, Products

Panasonic's ETQ-P8M/AM*J Series low-power choke coils are designed to withstand tough circumstances and are ideal for automotive applications due to their small size and excellent performance. These coils provide good thermal durability and 30G vibration resistance while supporting high current output (up to 53A for R33 versions). They fulfill RoHS environmental regulations and function steadily at 160°C, including self-heating, thanks to their dispersed air gap design rather than discrete gaps. Benefits include shock and vibration resistance, great inductance stability across a broad temperature range, strong end device reliability, and support for extremely tight design specifications. reduces humming sounds to guarantee smooth functioning in demanding settings.

Product Description

The Panasonic surface-mount power inductor ETQPAMR68JFW is an automotive-grade component with notable features, as follows:

Basic Specifications

It has an inductance of 0.68µH with a tolerance of ±15%, and the DC resistance at 20°C is typically 0.70mΩ, with a maximum of 0.77mΩ.

Size Dimensions

The size of the inductor is 17.2×15.6×10.5mm, which is relatively compact and can meet the space-saving requirements of automotive electronic control units and other applications.

Current-carrying Capacity

Its rated current is 65A under the condition that the overall temperature rise is 40K when installed on a high-heat-dissipation multi-layer substrate, and the saturation current is 53A.

Temperature Characteristics

The guaranteed operating temperature range is -40°C to +160°C, including its own temperature rise. It can also be used briefly at temperatures below 180°C.

Vibration Resistance Performance

The inductor has good vibration resistance with an amplitude of less than 5mm, a scanning speed of 1 oct/min, a frequency of 5-2000Hz, 2 hours in each of the three directions (total of 6 hours), and a vibration resistance of 71G.

Structural and Material Advantages

Made of metal-magnetic materials, silicone resin, and coil windings. The integrated-molding structure formed by the metal-composite magnetic core has no gaps, low leakage flux, which reduces noise interference and benefits high-density layouts.

Compliance Standards

It complies with the AEC-Q200 standard for automotive applications and also meets the requirements of the RoHS directive, providing high reliability and environmental friendliness.
