TDK offers lead-free NTC thermistors for automotive

Japanese electronics company TDK Electronics has launched its L862 (B57862L) NTC thermistors with bendable wires and the L871 (B57871L) lead spacing NTC thermistors that can be used in automotive and industrial applications.

The thermistors can be used in automotive battery packs as well as power banks, energy storage and drones. They offer short response time and high measuring accuracy.

Both series are lead-free and can measure temperatures between -40° C and +155° C with a tolerance of ±1% and ±3% respectively. At room temperature, their maximum power dissipation is 60 mW. Both series are available with different rated resistances between 1 kΩ and 100 kΩ and different R/T characteristics. After 10,000 h at +70° C, the deviation of the resistance at room temperature R25 is less than 3%.

The sensor element of the L862, which is encapsulated with a black epoxy coating, is just 2.6 x 6.5 mm (D x H) in size and has insulated leads of silver-plated nickel wire (AWG 30, Ø 0.25 mm). The total length of the sensor including the wires is 50 mm, with 6 mm stripped. While the dissipation factor (δth) of the sensor is 1.4 mW/K, its thermal cooling time constant (τc) is 14 s.

The sensor element of the L871 is also encapsulated with a black epoxy coating. It is just 2.8 x 6.0 mm (D x H) in size and has copper-clad steel wires (Ø 0.4 mm) with a spacing of 2.5 mm. The dissipation factor of the sensor is 3 mW/K, and its thermal cooling time constant is 9 s.

Musk’s Government Role Is Costing Tesla—Literally

Tesla CEO Elon Musk is making headlines again—but this time, it’s not about a new product or big innovation. Instead, he’s calling his new government role “a very expensive job.”

Musk recently joined the Trump Administration’s Department of Government Efficiency (DOGE), and the move is stirring up backlash. Protesters across the U.S. and even parts of Europe are showing up at Tesla dealerships to express their anger over DOGE’s controversial actions—like cutting government programs and accessing personal data.

The backlash is hitting Tesla where it hurts. Since Trump’s election in November, Tesla stock surged to a high of $479 in December but has since dropped nearly 50%. “My Tesla stock and the stock of everyone who holds Tesla went roughly in half,” Musk said during a town hall in Wisconsin.

And it’s not just about stock prices. Sales in Europe fell 45% in January, and Tesla trade-ins are at an all-time high—many of them going toward non-Tesla vehicles. Former fans are ditching their Teslas in protest of Musk’s political activity.

With Q1 delivery numbers expected to be down 7% year-over-year, some investors and employees are urging Musk to rebalance his priorities. As analyst Dan Ives puts it, “Musk needs to better balance being CEO of Tesla and running DOGE.”

Whether this turns into a short-term dip or a long-term brand issue, one thing is clear: the pressure is on.
