Unshielded DIP Power Inductors - SPK Series

Product Overview

The SPK Series Unshielded DIP Power Inductors from SHENZHEN LANTU MICRO ELECTRIC TECHNOLOGY CO., LTD. are designed for spike suppression and general power applications. These inductors offer a low-cost solution with high power handling, high saturation, and low resistance. Their unshielded construction, combined with a core encapsulated in UL heat shrink tubing, provides excellent mechanical and environmental protection. Available in various package sizes and a wide inductance range, they are suitable for automated insertion processes and meet RoHS, Halogen Free, and REACH compliance standards. Key applications include TVs, audio equipment, telecommunication devices, noise filters, chargers, fast charge circuits, and DC/DC converters.

Packaging Information:

Reminders for Using These Products:

• Storage: Within 12 months. Conditions: temperature 5~40C, humidity 35~65% RH or less.
• Environment: Do not use or store in gas corrosive environments (salt, acid, alkali, etc.).
• Handling: Avoid direct contact with terminals due to oil secretions. Handle with care to prevent damage. Do not bend terminals excessively.
• Cleaning: Do not rinse coils; contact SXN if cleaning is necessary.
• Magnetic Fields: Keep away from magnets or magnetic fields.
• Soldering: Preheat components before soldering. Temperature difference between solder and chip should not exceed 150C. Post-mounting soldering corrections must be within specified conditions to avoid overheating.
• Thermal Design: Account for self-heating when power is ON.
• Layout: For non-magnetic shield types, careful coil placement on the circuit board is required to prevent malfunctions due to magnetic interference.
