Some design challenges involve multiple component types, cross-disciplinary constraints, or performance requirements that no standard product line addresses on its own. This is where Vishay's full engineering depth comes together. We work with you to understand the complete system requirement and scope a solution that draws on our capabilities across semiconductors, passives, magnetics, sensors, and hybrid assemblies.
This Path is the Right Fit if any of These Describe Your Situation
You are in the right place if:
- Your application requires components from more than one product category working together
- You have a system-level performance requirement, not a specific part number in mind
- Your application is highly specialized, such as aerospace, medical implant, or defense
- You have looked through Vishay's standard catalog and nothing comes close to your spec
- You need a single engineering team to own the full solution, not manage multiple vendors
A category-specific page may be a better fit if:
- You already know the component type you need and just need it modified or designed to a tighter spec
- Your challenge is confined to a single product family, such as a re-configured resistor or capacitor
- You have a part number or product family in mind and want to discuss re-configuration options
Custom Service designs developed through this program are created exclusively for you. We do not add customer-specific designs to our general product catalog or make them available to any other party. Your requirements, your specifications, and your intellectual property remain confidential throughout every stage of our engagement.
Before You Reach Out
You do not need a finished specification to start. Here is what helps.
A description of the application
What is the end product or system? What environment will it operate in? Industry context helps our engineers understand constraints you may not have fully specified yet.
The performance gap you are trying to close
What is the standard product or existing design failing to do? Temperature, tolerance, size, voltage, reliability: even a partial list helps scope the right approach quickly.
Volume and timeline expectations
Are you prototyping or designing for production? Do you have a program timeline? This helps us recommend the right engagement path from the first conversation.
What to Expect
A straightforward path from first contact to scoped solution.
You describe your challenge
A brief description of your application and the problem you are trying to solve. No formal spec required at this stage.

What We Have Delivered
Complex challenges solved across industries and component boundaries.
Avoiding a Complete Redesign After a Panel Potentiometer was Made Obsolete
Challenge
The customer approached Vishay when their existing panel potentiometer supplier discontinued production of a part used on an established and popular piece of equipment. To avoid a costly redesign, an existing panel potentiometer needed to be adapted to meet the customer’s electrical requirements. It would also have to fit the control panel insertion / retention envelope and existing markings, in addition to the PCB assembly attachment system.
DC-Link Capacitors With Tab Terminals For Harsh Vibration Profiles
Challenge
Our customer was evaluating a solution for power electronics equipment that required the use of several DC-Link capacitors on the same PCB, while ensuring that the devices would support critical vibration profiles. The products being considered for the application had a significantly high mass of around 100 g, and were attached to the PCB via four lead wires with 1.2 mm diameters. While testing these parts under severe vibration profiles, the customer reported broken lead wires. The challenge was clear: how can such high mass parts withstand severe vibration profiles, while maintaining a similar footprint on the PCB?
mmWave Loss and Unstable Performance in a Satellite Payload
Challenge
While developing a next‑generation Ka‑band and W‑band satellite payload for a low‑Earth‑orbit communications constellation, an RF systems engineer encountered an unexpected challenge. Although the team designed a GaN power amplifier and low‑noise receiver chain to operate above 80 GHz, system testing revealed significant performance degradation. The active devices met their specifications, but once the signal left the die, system performance collapsed: Insertion loss exceeded the link budget by 1.5 dB Parasitic inductance from wire bonds and interconnects distorted matching Board-to-board variation caused gain and phase inconsistencies across flight units Commercial passive components were too large and introduced resonances above 70 GHz The design relied on an advanced organic PCB with thick‑film passives and LTCC modules. Despite extensive tuning and redesign cycles, performance drifted from build to build, introducing unacceptable risk to schedule and qualification.
