Vishay Intertechnology SMD Inrush Current Limiting PTC Thermistors Increase Board-Level Efficiency to Lower Costs

Core Insights - Vishay Intertechnology has launched a new series of insulated, surface-mount inrush current limiting positive temperature coefficient (PTC) thermistors aimed at enhancing board-level efficiency and reducing costs in automotive and industrial applications [1][2]. Product Features - The PTCES series devices can handle maximum energy up to 340 J and support high maximum voltages of 1200 VDC, all within a compact package [1]. - Compared to competing devices, the PTC thermistors offer up to 260% higher energy handling capabilities and 20% higher maximum voltages, allowing for fewer components in circuits, thus saving board space and lowering costs [2]. - These thermistors provide current limitation and overload protection for various applications, including AC/DC and DC/DC converters, energy dump circuits, on-board chargers, and motor drives [3]. Technical Specifications - The PTCES series consists of barium titanate thermistors with a resistance range of 60 to 1000 Ω and a maximum AC voltage of 350 to 800 VRMS [5]. - The devices are AEC-Q200 qualified for shock and vibration, capable of withstanding over 100,000 inrush power cycles, and feature a low profile of 9.6 mm [3][4]. - The operating temperature range is from -40 to +105 °C, with heat capacities of 2.4 and 2.6 J/K [5]. Availability - Samples and production quantities of the PTCES series thermistors are currently available, with lead times of 10 weeks [7]. Company Overview - Vishay Intertechnology is a major manufacturer of discrete semiconductors and passive electronic components, serving various markets including automotive, industrial, and medical [8].
