Thick Film Resistor Network Manufacturer

We design and manufacture specific thick film resistor network components for specialist applications. We work with customers to design and manufacture a technical solution in space-saving single-in-line packages.

Custom Thick Film Resistor Networks

High-volume resistor network applications include pull-up/pull-down, level translator, line termination and pulse squaring applications.

TSEC deliver custom resistor network products for more specialised applications, including:
Precise value matching of resistors for

We manufacture a wide range of customer-specific configurations, with or without resistor matching. Resistance ranges from 1 Ohm to 100MOhms in block resistor designs to over 1,000MOHms in high voltage meander designs.

With an engineering heritage extending back over 30 years, we focus on specific customer requirements, delivering reliable resistor network products that continue to perform to specification in demanding applications.

Low To Medium Volume Manufacture

High-volume manufacturing excels at delivering consistent quality at low costs via standardised and highly automated processes.

In contrast, TSEC tailor materials and processes to meet stringent performance specifications. The manufacturing process is optimised to enable multiple sample runs, prototype deliveries for approval and manufacture in the low to medium volume usually required for specialised applications.

Resistor Network Application Information

To develop an application-specific thick film resistor network device, TSEC requires the following information:

  • Number of resistors and values.
  • Tolerance.
  • Dimensional constraints.
  • Power / current rating.
  • Operating frequency.
  • Operating and maximum voltage.
  • Pulse withstand requirements.
  • Temperature Co-efficient.
  • Termination (SMD/T.Hole).
  • Number of terminals.
  • Length of pin.
  • Required date and quantity required.

Armed with this information, TSEC will design and manufacture custom resistor networks for your specific application.

Resistor Network vs Discrete Devices

A resistor network offers several advantages over discrete resistors including:

  • Saving space on board.
  • Reduced resistor drift and significantly improved temperature tracking.
  • Reduced system board interconnect and higher reliability.
  • Value matching.

Space Saving

A resistor network has only one packaging overhead rather than two (or more) with discrete devices. This eliminates issues with closely packed discrete devices on a system board.

The system board layout is simplified, improving reliability and reducing both the design time and system board cost. Inventory and qualification costs are also reduced.

Resistor Network Thermal Performance

Thermal effects can cause a variation in resistance between two discrete resistors. Proximity of external heat sources may impact the resistance of one discrete resistor relative to another. Manufacturing variables in discrete resistors can result in differences in self-heating effects.

A resistor network device with resistors in close proximity on the same substrate, with the same manufacturing process, resolves these issues. TCR matching issues are reduced or eliminated.

Reduced Interconnect

A resistor network replaces the system board interconnect with an interconnect on a fully tested resistor component. This approach can improve the overall reliability of the system.

Resistor Value Matching

Many precision instrumentation and measurement applications require resistor pairs, closely matched in value. Resistor networks deliver excellent resistor-to-resistor matching.

Example: Application Specific Thick Film Resistor Network Product:

Thick Film Resistive bridge pressure sensors for racing car application. These are more stable over temperature and time than semiconductor pressure elements.
