Enhancing Efficiency with Vishay's New PTC Thermistors

Introducing Vishay's Innovative PTC Thermistors

Vishay Intertechnology, Inc. (NYSE: VSH) has announced an exciting addition to its product lineup: a new series of insulated, surface-mount inrush current limiting positive temperature coefficient (PTC) thermistors. Aimed at boosting board-level efficiency and minimizing costs, these devices are set to make a strong impact in automotive and industrial markets.

Thermistors that Outperform Competitors

The newly launched PTCES series offers remarkable features, including energy handling capabilities up to 340 joules and maximum voltages reaching 1200 volts. This combination of attributes makes these thermistors particularly compelling for circuit designers. Compared to other options on the market, Vishay's devices stand out with energy handling capabilities that can be up to 260% higher, which means fewer components are required, ultimately saving board space and lowering costs.

Applications and Versatility

These thermistors are perfect for various applications, including AC/DC and DC/DC converters, energy dump circuits, motor drives, and on-board chargers for electric vehicles. As self-protecting components, they can endure over 100,000 inrush power cycles and have received AEC-Q200 qualification, ensuring robustness against shock and vibration. This quality eliminates the need for reinforced mounting adhesives, simplifying installation and enhancing reliability in critical applications.

Specifications of the PTCES Series

Vishay's PTCES series thermistors offer users a host of advantageous specifications:

• Series: PTCES
• Resistance (R25): 60 to 1000 ?
• Tolerance (R25): 30%
• Max. AC voltage: 350 to 800 VRMS
• Max. DC voltage: 500 to 1200 VDC
• Maximum energy: 240 to 340 J @ 25 °C
• Heat capacity: 2.4 to 2.6 J/K
• Operating temperature: -40 to +105 °C

Compact Design and Easy Integration

With a low profile of just 9.6 mm, these RoHS-compliant and halogen-free thermistors are designed for seamless integration into diverse systems. Their construction includes a solder-connected ceramic PTC encapsulated in an UL 94 V-0 compliant, self-extinguishing plastic housing, which also features insulation up to 3 kV AC. These qualities allow them to be automatically mounted by pick and place machinery, significantly reducing placement costs for manufacturers.

Availability and Further Information

Samples and production quantities of the PTCES series thermistors are currently available, with expected lead times of around 10 weeks. Vishay Intertechnology operates as a pivotal supplier in the electronic components market, recognized for its extensive portfolio comprising both discrete semiconductors and passive elements vital for innovative designs across multiple sectors, including automotive, aerospace, and telecommunications.
