15M623J

Overview

The 15M623J is a fixed inductor manufactured by Gowanda Electronics, classified as a molded unshielded RF coil with axial leads. It features an inductance of 620 µH and a maximum DC resistance of 25.9 Ohms. The component supports a maximum current rating of 55 mA. Designed for through-hole mounting, this axial leaded device is part of the ER15M series, offering non-shielded construction suitable for specific radio frequency applications requiring defined magnetic field characteristics.

Feature Summary

• Molded unshielded construction for controlled magnetic field distribution
• Axial lead configuration for through-hole PCB mounting
• Fixed inductance value optimized for RF circuit integration

Applications

• Radio frequency signal processing circuits
• Broadband power transformer biasing networks
• Industrial electronic filtering applications

Procurement Notes

Verify the exact suffix designation during procurement, as variants such as 15M623JLF may exist with different material compliance specifications. Confirm that the axial package dimensions align with the target board layout constraints. Ensure the 55 mA current rating meets the operational requirements of the specific circuit node to prevent saturation or thermal issues. Cross-reference the datasheet for self-resonant frequency limits if high-frequency performance is critical.

Selection Notes

Select this component when an unshielded axial inductor is required for RF applications to minimize capacitive coupling effects associated with shielding. The 620 µH value and 25.9 Ohm resistance define its impedance profile; ensure this matches the circuit design without excessive voltage drop. Consider the 55 mA limit carefully, as exceeding it may alter inductance values. This part is suitable where physical size allows for axial leads and where magnetic shielding is not mandated by surrounding sensitive components.

Part Context

The 15M623J belongs to Gowanda Electronics' ER15M series of molded RF inductors. This series provides various inductance values ranging from 0.15 to 240 µH in some configurations, though this specific model offers 620 µH. The manufacturer specializes in high-performance magnetic components for aerospace, defense, and medical sectors, often providing custom designs alongside standard parts like this axial coil.

Replacement Considerations

Direct substitutes within the same series include 15M683J (680 µH) and 15M753J (750 µH), which share similar physical and electrical characteristics but differ in inductance. Verify compatibility with adjacent circuit parameters before swapping. No other manufacturers are explicitly confirmed as direct replacements in public documentation.
