Self-protecting units with built-in power dealing with ship 340 J, function R25 values as much as 1.5 kΩ, and help excessive voltages as much as 1200 VDC—decreasing part counts.
Vishay Intertechnology, Inc.has unveiled the PTCEL Excessive Vitality collection, a brand new line of inrush present limiting optimistic temperature coefficient (PTC) thermistors. Engineered to boost efficiency in energetic cost and discharge circuits for each automotive and industrial functions, these thermistors set a brand new commonplace with their superior power dealing with and versatile design.
The Excessive Vitality collection thermistors are able to managing power, which is 5 occasions higher than what competing units can deal with at elevated ambient temperatures. This substantial improve in power dealing with is complemented by a broad number of resistance at 25 °C (R25) values, starting from 150 Ω to 1.5 kΩ, and the flexibility to face up to excessive voltages as much as 1200 VDC. These options collectively contribute to greater effectivity and higher flexibility in circuit design.
The important thing options are:
- Vitality absorption ranges as much as 340 J
- Helps over 100,000 inrush energy cycles
- Excessive resistance to non-switching peak powers as much as 25 kW
One of many key benefits of the collection is its strong efficiency at excessive temperatures. The units keep their power dealing with capabilities with 180 J at 85 °C and 130 J at 105 °C, permitting engineers to cut back the variety of parts wanted of their designs, saving area and reducing prices. Moreover, the thermistors provide a excessive switching temperature and might function as much as +105 °C, offering a warmth capability of two.6 J/Ok throughout all resistance values.
The thermistors are AEC-Q200 certified and have a self-protecting design that eliminates the danger of overheating. This makes them excellent for functions requiring present limitation and overload safety, equivalent to AC/DC and DC/DC converters, DC-Hyperlink circuits, battery administration techniques, emergency discharge circuits, on-board chargers, house power storage techniques, warmth pumps, motor drives, and welding tools. The units are constructed to endure greater than 100,000 inrush energy cycles and might stand up to non-switching peak energy surges as much as 25 kW, guaranteeing excessive resilience and long-term reliability.
Constructed from barium titanate, every thermistor consists of a ceramic pellet soldered between two tinned CCS wires and coated with a high-temperature silicone lacquer that complies with UL 94 V-0 requirements. The thermistors can be found in tape-on-reel packaging, facilitating automated dealing with by pick-and-place tools, thus decreasing placement prices. They arrive with an ordinary leadwire pitch of 10 mm, with choices for five.0 mm and seven.5 mm pitches additionally out there. SPICE and 3D fashions are offered for these RoHS-compliant units. Samples and manufacturing portions of the PTCEL Excessive Vitality collection thermistors are actually out there, with a lead time of 10 weeks, prepared to satisfy the calls for of automotive and industrial functions.
