Anti-Surge Resistors
(RCR)Introduction (RCR)
Thick-film anti-surge resistor handles large pulse loading.
A new range of anti-surge axial leaded power resistors, metal glaze resistive element on ceramic substrates, from Token Electronics.
A carbon film resistor replacement, the new RCR series thick-film style resistors offer numerous benefits over the previous style devices, namely reduced costs, excellent thermal compliance, optimised a variety of surge capabilities and better solder joint reliability against temperature cycles.
Token succeeded in commercialising the compact thick-film type leaded resistors with high power and high antisurge characteristics, meeting latest design engineer requirements and making the parts suitable for industrial, measurement and telecommunication applications as well as for automotive circuits, like Electrical Control Units (ECU) and Air-Bag Systems.
The antisurge characteristics of Token's latest metal glaze power film style resistors are superior to standard metal film resistors. The power film types of RCR resistors are available: 0.25W to 10W power rating, max working voltage up to 3000V and max overload voltage 5000V. The resistance range is 1Ω ~ 100MΩ at operating temperature range -20°C~+155°C.
All RCR series devices are RoHS-compliant, and compatible with high temperature soldering processes normally employed for lead free solders. Resistors are also available in various forming styles and different leads for different applications. Contact us with your specific needs.
