Overview
The Gowanda Electronics 10M821J is a fixed, unshielded wirewound inductor with an axial lead configuration. It features a nominal inductance of 8.2 µH and a maximum direct current resistance (DCR) of 2.7 Ω. The component has a self-resonant frequency (SRF) of 55 MHz and a DC current rating of 155 mA. Physical dimensions include a minimum overall length of 0.240 inches and a maximum of 0.260 inches.
Feature Summary
- Non-magnetic construction designed to prevent magnetic interference in sensitive circuits
- Unshielded wirewound design suitable for high-frequency RF applications
- Axial lead termination for through-hole mounting
Applications
- Sensitive high-frequency circuits requiring non-magnetic components
- RF coil applications
- Aerospace and defense electronic systems
Procurement Notes
Verify the specific suffix (e.g., J vs KLF) against official Gowanda documentation to confirm tolerance and packaging details. Confirm that the 155 mA rating aligns with your thermal management requirements. Ensure the unshielded nature does not cause EMI issues in your specific layout. Cross-reference the physical dimensions with your PCB footprint constraints before finalizing procurement.
Selection Notes
Select this component when non-magnetic properties are critical to avoid signal distortion in high-frequency environments. The 8.2 µH value and 55 MHz SRF make it suitable for specific RF tuning needs. Consider the axial package style for manual or standard automated assembly processes. Evaluate the 2.7 Ω DCR impact on circuit efficiency at the operating current level.
Part Context
Gowanda Electronics specializes in precision-engineered magnetic components for demanding industries. The 10M series represents their line of non-magnetic inductors, built to withstand harsh environments while maintaining electrical stability. These components are distinct from standard shielded inductors due to their specialized core materials and lack of magnetic shielding.
Replacement Considerations
Direct substitutes must match the 8.2 µH inductance, 155 mA current rating, and non-magnetic construction. Verify that any replacement maintains the 55 MHz self-resonant frequency and similar physical dimensions for axial mounting compatibility.
