Part of a trio of devices, the MBR40250 silicon Schottky diode breaks the 200V barrier with a breakdown-voltage rating of 250V. It also features a lower forward voltage in the order of less than 1V. The 40A device comes in a T0-220 package/die and is suitable for use in plasma/LCD television, power supply, consumer, and automotive applications. Rounding out the group are the 4A MBRS4201 and 3A MBRS3201 Shottkys. Both devices specify a breakdown voltage of 200V and are available in SMC packages. Prices range from $0.30 to $1 each/10,000. ON SEMICONDUCTOR, Phoenix, AZ. (800) 282-9855. 
Supporting the migration from 8-bit to 32-bit microcontrollers, the LPC2130 series devices debut as cost-effective 32-bit MCUs that operate at twice the speed with up to four times the performance of existing 32-bit ARM MCUs. Five MCUs in the series, the LPC2131, LPC2132, LPC2134, LPC2136, and LPC2138 come with up to 512 KB of 128-bit wide flash memory. This allows access to 32-bit words in a single fetch, allowing the CPU to run at 60 MHz (54 MIPS) without wait-states. Each includes a real-time trace and debug capability that allows users to continuously debug a system under actual conditions. Other shared features include 3V operation, dual 8-channel a/d
converters and a 10-bit d/a converter, brownout detection, and power-on reset. The LPC2131, LPC2132 and LPC2138 are available now, priced at $3.20, $3.90, and $7 each/10,000, respectively. The LPC2134 and LPC2136 will be available in the first quarter of 2005. ROYAL PHILIPS ELECTRONICS, San Jose, CA. (408) 617-4700.
The WB5 series wedge-based, warm-white LEDs deliver a color output comparable to standard 5-mm, wedge-based incandescent bulbs. Specifying a color temperature of 3,500K, the components emit similar eye and atmosphere comforts as traditional incandescents. They employ a flat-face lens design with an internal reflector that exhibits a 180° viewing angle. Other features include voltage ratings
from 2.5V to 48V, operating currents from 10 mA to 30 mA, and a service life up to 100,000 hours. In a package measuring 20.37 mm in length and 5.842 mm in diameter, price is $0.64 each/10,000. BIVAR, INC., Irvine, CA. (800) 772-2377.
Reporting the industry's highest current density in the smallest package, the E70340-xxx series filter inductors
specify current ratings from 100A to 250A. At the top of the series, the 8-µH CWS E-70304-010 withstands up to 250A in a 1.75" x 1.75" x 1.25" package. The component exhibits a dc resistance of less than 0.7 mΩ. Measuring 1.7" x 1.7" x 1.25", the 20-µH E-70304-005 is rated at 150A. The inductors are wound using thick helical coils on a Sendust powder E-core construction with distributed air gaps using ceramic binders, allowing them to operate in temperatures from -55°C to +155°C. High-potential rating for winding-to core-isolation is 1 kVdc. Price is $7.50 each/10,000. CWS COIL WINDINGS SPECIALIST, Santa Ana, CA. (714) 547-4446.
The Model 6822 dual-channel, 6U VMEbus signal acquisition and processing board employs a VXS interface that provides two 1.25-GB/s switched serial fabric ports to the VME backplane. With the aid of 12-bit a/d converters, the board samples at rates up to 215 MHz, supported with several interface options. Up to four front panel data port (FPDP II) connectors deliver output data at speeds up to 320 MB/s each. The board couples its a/d converters to two Xilinx Virtex-II Pro FPGAs, each supported by 16 MB of flash memory and 128 MB of SDRAM. Additionally, it is available in commercial, air-cooled, and conduction-cooled versions. Price starts at $8,995. For more details, contact Mario Schiavone at PENTEK INC., Upper Saddle River, NJ. (201) 818-5900, ext. 760.
Addressing high-speed digital systems, the PN 701182-1 stand-alone bit-error rate tester (BERT) provides an unframed, serial binary output ranging from T1 to STM-1 rates. Outputs can be encoded with applicable zero suppression techniques. Signal levels include differential and single-ended AMI, CMI, ECL, PECL, RS422, and LVDS levels for copper and STM-1 (OC3) for fiber-optic interfaces. All I/O is accessible through rear-panel, concentric twin-axial connectors or industry standard BNCs. The SFP I/O can be electrical, if an Infiniband or Fiber Channel device is present. Single-unit pricing begins under $5,000. TECHNISYS, Woodbury, NJ. (856) 848-9001.
