Product Attributes

Introduction

This product specification covers the 10D471K, detailing its dimensions, key electrical characteristics, operating and storage temperatures, primary composition, electrical performance test methods, key mechanical properties, and climate/endurance test methods. Key electrical characteristics include nominal varistor voltage, maximum continuous AC and DC operating voltage, leakage current, maximum clamping voltage, and surge current capacity. Mechanical performance tests cover tensile strength, bending, torsion, vibration, bump, shock, solderability, resistance to soldering heat, resistance of marking to solvents, resistance of component to solvents, and flammability. Climate and endurance tests include rapid temperature change, high-temperature storage, damp heat storage, low-temperature storage, damp heat load, upper category temperature endurance, and pulse current life testing.
