Overview
The Delevan 103R-182F is a surface-mount RF inductor with an inductance of 1.8 µH and a tolerance of 1%. It features a non-shielded construction suitable for PCB mounting. The component has a maximum DC resistance of 920 mOhms and a minimum Q factor of 25. Its self-resonant frequency is specified at 28 MHz, with a maximum DC current rating of 325 mA. The physical dimensions are 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height.
Feature Summary
- Non-shielded SMD design for RF applications
- High precision 1% inductance tolerance
- Standard two-terminal surface mount termination
Applications
- RF circuit filtering
- Impedance matching networks
- General radio frequency signal processing
Procurement Notes
Verify the specific manufacturer designation, as API Delevan assets may be held by different entities. Confirm RoHS compliance status directly with the supplier, as documentation varies across sources. Ensure the ordering suffix matches the required packaging quantity, typically supplied in reels or bulk depending on the distributor. Cross-reference the exact datasheet version to confirm electrical parameters before finalizing procurement orders.
Selection Notes
Select this component when a precise 1.8 µH value is required with tight 1% tolerance. The non-shielded design necessitates careful layout consideration to prevent magnetic interference with nearby components. Verify that the 325 mA current rating meets the application's peak current demands. The 28 MHz self-resonant frequency defines the upper operational limit for effective inductive behavior.
Part Context
This part belongs to the 103/R series of fixed RF inductors manufactured by Delevan. These components are designed for high-frequency applications requiring stable inductance values. The series offers various inductance options within a compact 1008 (2520 metric) package size, catering to space-constrained electronic designs.
Replacement Considerations
The 103R-182H serves as a functional substitute with identical 1.8 µH inductance but differs in having a 3% tolerance and a maximum DC resistance of 720 mOhms. Users must verify if the looser tolerance and lower resistance profile align with their specific circuit requirements.
