Vishay has introduced a series of multi-turn, surface-mount cermet trimmers for industrial use over -55 to +140°C. The 4 x 4mm potentiometers, called the TSM41, are sealed to IP67. They are available in both top and side adjustment styles, and in 16 values between 10Ω and 1MΩ (in 1-2-5 spacing). Adjustment is nominally over 12 turns. Power rating is 250mW ...

Stable 200V 1206 SMD resistors meet AEC-Q200
Stackpole has improved the working voltage ratings of its RNCE series of SMD (surface-mount) thin film resistors to: RNCE0402 75V 63mW RNCE0603 100V 100mW RNCE0805 150V 125mW RNCE1206 200V 250mW. (Power rating is at 70°C. For lower resistances, √(PxR) will reduce max voltage.) “Many thin film resistors fail to maintain stability under harsh conditions and over extended periods,” according to ...
100A powdered iron automotive inductors stable at +180°C
Vishay is aiming at vehicles with a set of high-current through-hole powdered iron alloy inductors. “Compared to competing ferrite-based solutions, IHDM-1107BBEV-2A and IHDM-1107BBEV-3A offer 30% higher rated current and 30% higher saturation current levels at +125°C,” according to the company. “The inductors’ soft saturation provides a predictable inductance decrease with increasing current, independent of temperature.” They come in a 1107 ...
Knowles adds to safety-certified MLCCs
Knowles has brought out a range of X1/Y2 safety-certified surface-mount multilayer ceramic capacitors (MLCCs). The safety-certified MLCCs have a voltage rating between 310Vrms and 500Vrms, including the first class Y2 MLCC on the market to have a voltage rating as high as 500Vrms (Table 1). As a result, these MLCCs are suitable for ensuring safe operation of high-power AC/DC converters. ...
Automotive decline hits Europe component market, says DMASS
The European electronic components distribution market is suffering from a declining automotive sector, reports DMASS Europe. The electronic components distribution industry body represents approximately 85% of the European components DTAM. DMASS said that European semiconductor distribution sales in Q2 2025 fell 14% compared to Q2 2024. Austria experiencing the steepest drop (36.6%) followed by France (20%), Germany and Ireland both ...
Ferrite E cores up to 160mm
TDK has introduced ferrite ‘E’ cores up to 40 x 80 x 160mm for industrial applications such as motor drives. The largest one is made from N87 ferrite, while most of the rest also come in N88 or N97. One, measuring 80 x 40 x 38mm, comes in N97, or also N95. When even more magnetic mass is needed, the ...
9.5mm cermet trimmer potentiometers
Vishay has announced a series of industrial grade through-hole 3/8inch (~9.5mm) square single-turn cermet trimmer potentiometers. As well as flush slot operation, there are extended shaft and finger knob versions (see photo). The family is called M61, and it includes both top and side adjustment styles. Resistance options span 10Ω to 2MΩ (± 10 %) in a 1 – 2 ...
1kW planar transformers for demanding applications
Irncore has introduced a series of 49 x 40mm 1kW planar transformers, designed for military, aerospace, automotive and industrial applications. Called the PL105xx family, there are designed to run at between 100 and 700kHz, and are 19.5mm tall. Operation is over -55 to +130°C. For military and aerospace use there are space-qualified variants that meet Mil-Std 981 Class S, and for ...
2.8mm ceramic core inductors
Knowles is aiming 1008 size (2.8 x 2.6 x 2.3mm) ceramic core RF inductors at medical and defence markets. The CL1008-2 family have copper barrier plating for non-magnetic applications and come in nine values from 12nH (at 50MHz) to 10μH (2.5MHz). The company is emphasising high Q, which for those two parts is 50 at 500MHz, and 20 at 7.9MHz ...
Three-phase power filtering up to 32A
Rutronik is aiming at 3-phase industrial control cabinets with a DIN-rail mount mains filter series from Schurter. “The housing, with a width of just 44mm, requires extremely little space on the mounting rail,” said distributor Rutronik. “The single-stage filter is available as a standard version or with high attenuation. FPAC RAIL impresses above all with its leakage current of just ...
