LL1608-F33NK

Overview

The LL1608-F33NK is a fixed multilayer chip inductor manufactured by Toko America Inc. It features an unshielded design with a nominal inductance of 33 nH and a maximum DC resistance of 650 mΩ. The component supports a current rating of 300 mA and operates within the 800 MHz to 3,000 MHz frequency range. It utilizes a standard 0603 (1608 Metric) surface-mount package.

Feature Summary

• Unshielded multilayer construction for high-frequency applications
• Optimized performance for operation between 800 MHz and 3,000 MHz
• Standard 0603 footprint compatible with surface-mount assembly

Applications

• High-frequency circuit filtering
• RF signal processing components
• Microwave application modules

Procurement Notes

This component is classified as obsolete (EOL). Procurement verification must confirm availability through secondary market channels rather than direct manufacturer distribution. Sourcing requires careful validation of part authenticity and storage conditions due to end-of-life status. Buyers should verify lead times and minimum order quantities with authorized distributors handling surplus inventory.

Selection Notes

Selection requires matching the 33 nH inductance value against specific circuit impedance requirements. Designers must account for the 650 mΩ DC resistance impact on power efficiency. The unshielded nature necessitates layout considerations to prevent electromagnetic interference with adjacent components. Verify that the 300 mA current rating exceeds peak operational loads.

Part Context

The LL1608 series represents Toko's ultra-miniature laminated chip inductors designed for high-frequency markets. This specific model belongs to the F33 variant family, distinguished by its 33 nH nominal value. The series targets compact electronic devices requiring precise RF characteristics within a minimal physical footprint.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative sourcing from authorized distributors or cross-reference tools is recommended. Verify pin compatibility and electrical parameters before adopting any third-party equivalents.
