Thick Film Resistors For Specialist Applications
TSEC specialises in the design and manufacture of thick-film resistors for specialised applications.
We work closely with customers to fully understand their application requirements and environmental conditions before embarking on the Thick film resistor design and manufacturing process.
We specialise in medium to low-volume design and manufacture of application-specific Thick film power resistors and high-voltage resistors. We also deliver heater resistors for medical applications, precision resistor networks, and obsolete resistor replacements.
Low to Medium Volume Resistor Manufacture
Low-volume custom resistor requirements are often of little interest to major resistor manufacturers. In contrast, TSEC’s manufacturing process is optimised to support thick film resistor manufacture in the low to medium volume usually required for specialised applications. Prototype Thick film resistors for analysis and approval can be delivered before committing to production.
Thick film resistor materials and processes are tailored to meet demanding performance requirements. TSEC has long-term experience in the best combination of materials and manufacturing processes to address a wide range of applications, combined with excellent relationships with many resistor material suppliers.
Specialist suppliers include Ferro, ESL, Heraeus, and Metech. New materials are regularly approved and added to the portfolio.
Why Thick Film?
Thick film resistors are robust and deliver excellent power-handling capabilities compared to other resistor technologies. The technology delivers high maximum voltage specifications in a compact form factor, with a wide range of resistance values available to meet diverse application needs.
Thick film substrate technology is easily customisable for specific applications. This includes substrates of unusual shapes or sizes to fit in difficult-to-access spaces in specialised equipment.
Thick Film Resistor Applications
Thick film resistors deliver resistance values from a few Ohms to GigaOhms, whilst handling significant power loads in a compact form factor. They deliver stable performance characteristics at a reasonable cost. Thick film resistor technology is widely regarded as the most cost-effective solution for high-voltage and high-power applications.
Thick film resistor technology excels in the following applications:
- High Power Handling: Power supplies, LED drivers and motor drivers
- High Resistance: Leakage detection and high-impedance circuits
- Harsh Environmental Conditions: Automotive, industrial and military electronics
- High Voltage Applications: X-ray machines, CRT monitors, high-voltage power supplies and surge protection
- Where there are space constraints
- Where cost is a concern
Required Application Information
The materials used for both the resistance element and substrate, along with the resistor design and manufacturing process, all directly impact electrical performance. To design thick film resistors that meet specific application requirements, we need detailed information about both the application and its operating environment. Wherever possible, this should include:
- Resistance value.
- Tolerance.
- Dimensional constraints.
- Power/current rating.
- Operating frequency.
- Operating and maximum voltage.
- Pulse withstand requirements.
- Temperature Coefficient.
- Environmental conditions (temperature, moisture, chemicals).
- Termination (SMD/T.Hole).
- Number of terminals.
- Length of pin, plating or surface mount pad specification.
- Required date and quantity.
