What's "COOL"

German Engineering

Why do many of the Tier 1 and Tier 2 European automotive suppliers prefer Vishay? In this new module, you will learn the unique advantages of German Engineered Vishay Draloric / Beyschlag resistors.

Vishay Automotive Grade

Designers often associate Vishay Automotive Grade with automotive (AEC-Q200) qualification. In this module, we will clear up this misconception.

AEC-Q200

Do you know who started it? What are the tests required? Does it mean that you could now go and look for the cheapest AEC-Q200 qualified products?

PPAP & PSW

What is PPAP? Who is it for and what does it do? Do you always need to go for the highest level of PPAP?

Basic Design Considerations

Having a good basic understanding will help you to choose the components needed to make sure your design has a good performance-to-cost ratio. In this module, we will discuss "Standard Power Ratings and Voltage Ratings vs. Component Sizes" and "New Power Ratings and Voltage Ratings" available to help improve your designs.

Current Sensing

Are you using a low error rate ADC (hence higher cost) to improve your current sensing accuracy? What if you could use a higher error rate (lower cost) ADC to achieve the same or better accuracy? In this module, we will show you how.

Resistors for Dummies

Not an engineer? No problem. We have a module for non-engineers, too! If you want to know about resistors and Vishay resistors, this is the module for you.

Sulfur Resistance

Sulfur is present in the air. Do you know there are certain types of resistors that can fail because of sulfur? In this module, we will discuss the problem as well as their solutions.

Thin Film vs. Thick Film Resistors: Materials and Properties

What is the difference between a thick film resistor and a thin film resistor? How will your selection impact your design? In this module, we will review the materials, manufacturing processes, and properties of these two types of resistors.

What's "HOT"

Vishay High Performance Solutions

When ordinary is not enough, environments are harsh, reliability is vital, and performance really matters, you should think about Vishay’s high performance solutions!

Focus Products for xEV

Using a Vishay resistor solution with a diagram, the module explains how to choose Vishay resistors for powerful designs in the xEV market. The module also reviews xEV market trends in terms of resistors.

EV / HEV and 48 V

We will see the end of fossil fuel vehicles in the foreseeable future. This module will highlight the use of Vishay resistors and inductors in the new energy vehicles set to replace them.

48 V System

Current 12V system is no longer enough to cater to many new features of today’s cars. Features like turbo charging, regenerative braking systems for EV/HEV etc.

Pulse Handling Capability

Class accuracy for energy meters, for example, cannot be met if you don't pay attention to the pulse handling capabilities of the resistors used. In the worst case, a design can fail completely. In this module, we will discuss in some detail the options available to you.

Failure Modes of Resistors

Say good-bye to failure! In this module, we will discuss the various failure modes of resistors and show you how to prevent them. This will help to increase your products' reliability.

High-Temperature Resistors

Operating resistors above their allowed temperatures can cause failures, or even fires! Stop being filled with fear! Learn about the various high-temperature resistors for your high- temperature applications.

Thermal Management

With more and more components on congested PCBs, thermal management has become increasingly important. In this module, we will discuss how different materials and sizes affect thermal management.

Thermocycling Stability

Expansions and contractions due to high temperature changes cause stress to components' joint and PCBs, which will in turn lead to failures. In this module, we will discuss how different resistors will behave under the same thermal stress and what options are available to improve thermocycling stability.

Thermistors (Non-Linear Resistors)

Is R-value tolerance the only consideration for sensing accuracy? In this module, we will discuss, in addition to R-value, the other factors that impact temperature sensing accuracy.
