Product catalog summary

Overview: This document outlines the technical specifications and performance characteristics of automotive-grade power inductors and power choke coils. These components are designed for high heat resistance and reliability, featuring a metal composite core (MC) and compliance with AEC-Q200 and RoHS standards.

Key Features:

High Heat Resistance: Operates up to 150°C, including self-heating.
High Reliability: Maintains inductance stability under high DC current and temperature conditions, with high vibration resistance.
High Bias Current: Utilizes ferrous alloy magnetic material for excellent inductance stability.
Temperature Stability: Stable inductance over a broad temperature range.
Low Audible Noise: Achieved through a gapless structure with a metal composite core.
High Efficiency: Features low DC resistance and low eddy-current loss.
Shielded Construction: Provides additional protection and performance stability.

Recommended Applications:

Noise filters for drive circuitry requiring high temperature operation and peak current handling.
Boost-Converter and Buck-Converter DC/DC applications.

Specifications:

Operating Temperature Range: -40°C to +150°C (including self-temperature rise).
Storage Conditions: -5°C to +35°C, 85% RH max.
Standard Packing Quantity: Varies by model, ranging from 1,000 to 2,000 pcs/box.

Performance Characteristics:

Inductance vs DC Current: Detailed graphs provided for various models, showing inductance stability under different DC bias conditions.
Case Temperature vs DC Current: Performance varies based on PWB conditions, with specific heat dissipation characteristics noted.

Important Notes:

Design and specifications are subject to change without notice; consult the factory for current specifications before purchase or use.
Solderability is guaranteed for one year; expired products should not be used.
For higher operating temperature conditions, contact a Panasonic representative.

Protective Functions: Emphasizes the importance of ensuring that the power choke coil does not pose risks such as smoking, fire, or dielectric failure under abnormal conditions like overload, short-circuit, and open-circuit. Protective devices or circuits should be integrated into the end product to mitigate these risks.

Temperature Rise: The temperature rise of the power choke coil should be monitored in the actual end product to ensure it remains within the specified temperature class limits.

Dielectric Strength: Conducting dielectric withstanding tests at higher voltages than specified can damage insulating materials and reduce their lifespan.

Water Exposure: The power choke coil should not be used in wet conditions as it significantly reduces insulation strength.

Potting: Potting the power choke coil in certain compounds may damage the magnet wire coating. Consultation is advised if potting is intended.

Model Usage: Using the power choke coil in different products or conditions may not meet specifications. Consultation is recommended for such applications.

Mechanical Stress: Mechanical stress, such as dropping, can degrade the coil's characteristics. Stressed coils should not be used.

Buzz Noise: Buzz noise may occur when the coil operates within the audible frequency range or in burst mode. This should be checked in advance based on the circuit and board installation environment.

Solvent Exposure: Exposure to cleaning agents or solvents like toluene and xylene can significantly degrade performance. Consultation is advised if exposure is expected.

Static Electricity Measures: ESD protection should be implemented in circuit design to prevent static electricity from affecting the choke coil. Voltage should be kept below 200 V.

Printed Circuit Board Design: Specific guidelines are provided for PCB design to maintain isolation and prevent interference from leakage magnetic flux.

Environmental Considerations: The power choke coil is not designed for environments with corrosive gases or direct outdoor exposure. Such conditions can degrade performance and soldering quality.

Core Chipping and Cracking: Mechanical stress can cause chipping or cracking in the core, which may not affect quality but should be monitored.

AEC-Q200 Compliance: The product is tested according to AEC-Q200 standards. Consultation with Panasonic is recommended for detailed specifications and test results.

Package Markings: Packages should include product number, quantity, and country of origin, indicated in English.
