105-152K

Overview

The Delevan 105-152K is a fixed surface-mount RF inductor with an inductance of 1.5 µH and a tolerance of ±10%. It features a maximum DC resistance of 1.2 Ohms and a rated current of 280 mA. The component exhibits a minimum Q factor of 25 and a self-resonant frequency of 100 MHz. It utilizes an unshielded design with standard SMD/SMT termination style, housed in a nonstandard package measuring 0.1 inches in length and width, and 0.075 inches in height.

Feature Summary

• Unshielded construction for specific RF circuit requirements
• Surface-mount technology compatible with automated PCB assembly
• Standard termination style for reliable soldering

Applications

• RF signal processing circuits
• Impedance matching networks
• Filter applications in radio frequency systems

Procurement Notes

Verify the exact manufacturer designation as API Delevan or Delevan when sourcing. Confirm RoHS compliance status, as documentation indicates non-compliance. Ensure the unshielded variant matches the schematic requirements, as shielded versions exist within the same series. Validate the 1.2 Ohm DCR specification against the specific application load to prevent excessive voltage drop.

Selection Notes

Select this component for applications requiring a 1.5 µH value with moderate current handling up to 280 mA. The unshielded design may introduce electromagnetic interference; ensure layout spacing accounts for this. Compare the 100 MHz self-resonant frequency against the operating bandwidth to maintain inductive behavior. Consider the physical dimensions for tight PCB real estate constraints.

Part Context

This part belongs to the 105/R series of fixed inductors manufactured by Delevan. It serves as a passive component for filtering and tuning in electronic circuits. The series includes various inductance values and shielding options, with the 105-152K representing the unshielded, 1.5 µH configuration designed for general RF use.

Replacement Considerations

Direct substitutes include the 105R-152K and 105-152KS from the same manufacturer family. Verify that alternative sources provide identical electrical parameters, specifically the 1.2 Ohm DCR and 280 mA rating, to ensure circuit compatibility.
