8 4 7 4 Series M1330 QPL Inductors – M83446/23, M83446/24, and M83446/25

Category: API Delevan Inc, Electronics, Inductors

The provided datasheet describes the 8 4 7 4 Series M1330 QPL, which includes a range of Unshielded Surface Mount Inductors within the M83446/23, M83446/24, and M83446/25 series. These inductors are designed for surface mount applications and are specified under the military qualification program list (QPL). The datasheet provides detailed electrical and physical characteristics of each series, with three core material variants indicated—Phenolic, Iron, and Ferrite.

Electrical Specifications

Each inductor variant is characterized by part number, which specifies different inductance (µH), frequency (MHz), and current ratings (mA) parameters. The M83446/23 Phenolic Core series offers inductor values ranging from 94K µH to 20K µH, while the M83446/24 Iron Core series ranges from 22K µH to 30K µH, and the M83446/25 Ferrite Core series from 56K µH to 72K µH.

For instance, in the M83446/23 Phenolic Core series, the first part ’01F’ has an inductance of 0.10 µH with a maximum operating current of 1380 mA. Conversely, part ’13F’ from the same series indicates a higher inductance of 1.00 µH and correspondingly lower maximum operating current of 390 mA.

Similarly, values differ for the M83446/24 and M83446/25 series and are specified to allow for easy selection based on application requirements including operating current, inductance, and other electrical parameters.

Physical Characteristics

The datasheet includes the physical dimensions of the components, specified in both inches and millimeters. They mention the range for dimensions “A” & “C”, which cover the terminals and the weight maximum is provided (in grams).

Environmental and Operating Conditions

The operating temperature range for the Phenolic core inductors is from -55°C to +125°C, whereas the Iron and Ferrite core inductors operate within a temperature range of -55°C to +105°C. The datasheet defines the current rating at a 90°C ambient temperature with a rise of 35°C for the Phenolic core and 15°C for the Iron and Ferrite cores.

The maximum power dissipation at a 90°C ambient temperature is also detailed, with varying dissipation capacities for each core material: 0.210 W for Phenolic, 0.090 W for Iron, and 0.073 W for Ferrite.

Ordering and Marking

Parts are to be ordered according to the M83446/ part number and are marked with the Delevan brand, dash number, and date code followed by an ‘M’. Available packaging options include Tape & Reel with specified reel dimensions and quantity limits.
