Constant Current LED Drivers suit residential applications.
2015-11-11 14:31:06| Industrial Newsroom - All News for Today
Rated for 10 W output power, PDA010N Series provides flicker- and shimmer-free performance for broad range of residential LED fixtures. TRIAC-dimmable units are available with 3 constant current outputs of 350, 700, and 1,000 mA and are designed to operate using 108–132 Vac. Drivers require ≤ 0.25 A input power to deliver 78% efficiency at 120 Vac with power factor correction of ≥ 0.9 and THD of less than 20%. Measuring 3.14 x 3.07 x 0.992 in., IP67-rated units operate from 0–85°C.

SMT Current Sense Resistor has Kelvin 4-terminal connection.
2015-11-05 14:31:07| Industrial Newsroom - All News for Today
Offering resistance values from 0.01–0.05 Ω, Vishay Dale WSK1206 Power Metal Strip® current sense resistor reduces system errors while eliminating need for system calibration. Kelvin 4-terminal connection reduces TCR down to 35 ppm and enables tight tolerances of 0.1%, 0.5%, and 1.0% for optimized measurement accuracy. Solid metal nickel-chrome or manganese-copper resistive element with TCR <20 ppm/°C results in pulse tolerant, tight tolerance (0.1%) resistor in 1206 case size.

High Current Chokes mount on PCB.
2015-10-30 13:31:06| Industrial Newsroom - All News for Today
Available for single- and 3-phase applications with rated currents from 10–50 A, DKIH Series features open, lightweight design, suitable for suppressing EMI noise caused by power applications on PCB. Single-phase DKIH-1 Series offers voltage ratings of 300 Vac (IEC, UL), 250 Vac (CSA), and 425 Vdc, with inductance range of 0.30–0.90 mH. Three-phase DKIH-3 Series, rated to 600 Vac, offers inductance ratings from 0.08–1.10 mH. All common mode chokes operate from -40 to +100°C.
Brushed DC Motor Driver has integrated current sensing.

Available in 4.9 x 6.0 mm thermally enhanced small outline package, 8-pin DRV8871 brushed DC gate driver features integrated field-effect transistors (FETs) and suits space-constrained designs. Integrated current sensing enables designers using DRV8871 to avoid power loss and heat generation associated with external sense resistors. While DRV8870 features integrated regulation to limit current to external current-sense resistor, DRV8872 provides fault monitoring to increase system reliability.
