Fixed Inductors datasheet and documents for LLST-500
Fixed Inductors Overview
The LLST-500 is a fixed surface-mount power toroidal inductor manufactured by API Delevan. It features an inductance of 500 µH with a maximum DC resistance of 1 Ohm and a rated current of 500 mA. The component utilizes a shielded toroidal core design to minimize electromagnetic interference. It is classified as a non-standard package size within the LLST series, intended for applications requiring low-loss performance in compact PCB layouts.
Fixed Inductors Feature Summary
- Shielded toroidal construction reduces magnetic field leakage
- Low loss characteristics suitable for power applications
- Surface mount technology for automated assembly
Fixed Inductors Applications
- Power supply filtering circuits
- DC-DC converter input/output stages
- Signal processing choke applications
Fixed Inductors Procurement Notes
Verify the manufacturer designation as API Delevan or Delevan on official datasheets. Confirm RoHS compliance status as sources indicate potential lead content variations. Ensure the specific package dimensions match the non-standard footprint requirements of the target PCB design before ordering.
Fixed Inductors Selection Notes
Select this component when a shielded toroidal inductor is required for high-current power paths. The 500 mA rating and 1 Ohm resistance define its operational limits. Consider the physical size constraints due to the non-standard SMD package compared to standard rectangular inductors.
Fixed Inductors Part Context
The LLST series represents API Delevan's line of low-loss surface mount power toroids. These components are designed to replace larger through-hole inductors in modern electronics. The LLST-500 specifically targets mid-range inductance needs in portable and industrial devices.
Fixed Inductors Replacement Considerations
Cross-reference with other API Delevan LLST series parts for similar inductance values. Verify that substitute components maintain the same shielded toroidal geometry and current handling capabilities to ensure circuit stability.
