Overview
The Delevan 103R-682J is an unshielded surface-mount RF inductor with a nominal inductance of 6.8 µH and a tolerance of ±5%. It features a maximum DC resistance of 2.2 Ohms and a rated DC current of 210 mA. The component operates within a temperature range of -55°C to +125°C and has a minimum Q factor of 22 at its self-resonant frequency of 50 MHz. Its physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.
Feature Summary
- Unshielded construction for minimal magnetic interference
- Designed for high-frequency RF circuit applications
- Surface-mount technology for automated PCB assembly
Applications
- RF signal processing circuits
- High-frequency filtering networks
- Impedance matching stages in radio frequency systems
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with standard SMT reflow profiles and check for any recent product change notifications that may affect lead times or material composition prior to final procurement authorization.
Selection Notes
Select this component when an unshielded inductor is required for RF applications to prevent magnetic coupling issues. Confirm that the 210 mA current rating and 2.2 Ohm DC resistance align with the target circuit's power budget and signal integrity requirements. Validate that the 50 MHz self-resonant frequency suits the operational bandwidth.
Part Context
This part belongs to the 103/R series of fixed surface-mount inductors manufactured by Delevan. The series is characterized by compact footprints suitable for dense PCB layouts. The 103R-682J specifically utilizes an unshielded design, distinguishing it from shielded variants within the broader Delevan portfolio.
Replacement Considerations
Cross-reference with other 103R-series parts such as 103R-680MS for different inductance values. Verify mechanical footprint compatibility before substituting with generic equivalents.
