Unshielded DIP Power Inductor LanTu Micro SPK0608-152MB with UL Heat Shrink Tube and RoHS Compliance

Unshielded DIP Power Inductors - SPK Series

Product Overview

The LANTU SPK Series features unshielded DIP power inductors designed for spike suppression and general-purpose applications. These inductors offer a cost-effective solution with high power handling, high saturation, and low resistance. Encapsulated in UL heat shrink tubing for robust mechanical and environmental protection, they are available in various package sizes and inductance ranges. The SPK series is suitable for automatic insertion processes and complies with RoHS, Halogen-Free, and REACH standards, making them ideal for use in TV and audio equipment, telecommunication devices, noise filters, chargers, fast chargers, and DC/DC converters.

Technical Specifications

Inductance Tolerance Codes: J: 5%, K: 10%, L: 15%, M: 20%, P: 25%, N: 30%

Current Definitions:

• Saturation Current (Isat): DC current at which inductance drops 10% from its value without current.
• Temperature Rise Current (Irms): The actual value of DC current when the temperature rise is T 40 (Ta=25).
• Rated DC Current: The lesser of Isat or Irms.

Note: Part temperature should be verified in the end application due to factors like circuit design, component, PCB trace size and thickness, airflow, and other cooling provisions.

Reminders for Using These Products

• Storage: Store within 12 months under conditions of 5~40C and 35~65% RH. Soldering of terminal electrodes may deteriorate if storage period is exceeded.
• Environment: Do not use or store in environments with gas corrosion (salt, acid, alkali, etc.).
• Handling: Avoid touching electrodes directly with bare hands due to oil secretions. Handle products carefully to prevent damage from dropping or improper removal. Do not bend terminals excessively.
• Cleaning: Do not rinse coils. Contact the manufacturer if cleaning is necessary.
• Magnetic Fields: Do not expose products to magnets or magnetic fields.
• Soldering: Preheat components before soldering; ensure the temperature difference between solder and chip does not exceed 150C. Soldering corrections after mounting should be within specified conditions to avoid short circuits, performance degradation, or lifespan reduction.
• Thermal Design: Account for self-heating when power is applied; ensure sufficient thermal design margin.
• Layout: For non-magnetic shield types, carefully lay out coils on the circuit board to prevent malfunctions due to magnetic interference.
