Voltage regulators. Reported by the company to be the world's smallest voltage regulators for use with ceramic capacitors, the S-814 and S-817 series are also capable of operating tantalum or electrolytic capacitors. Both series feature low Equivalent Series Resistance (ESR), low current consumption, high output current and high-precision output voltage. The S-814 also has a low dropout voltage. The two series have a built-in power-off circuit which ensures long battery life, and a built-in short current limit circuit. Due to the increase in the use of tantalum capacitors in cell phones, tantalum capacitors are back ordered for up to 8 months.

Transformer.This linear-lamination power transformer rated at
2 to 12VA provides low clearances, ranging from 0.0625- to 1.0625-in. Designed especially
for low-profile applications, the TSB Series' semi-toroidal, split bobbin construction
also reduces radiated magnetic fields and offers lower inter-winding capacitance than
conventional, concentrically-wound designs. Associated Components Technology, Inc,Garden
Grove, CA. 
Miniature resettable fuse.The surface mount PFMD series
expands this company's wide range of resettable fuses, offering a more cost-efficient,
polymer-based PTC fuse. It offers improved solderability over previous versions and
slightly wider end-caps, which increase the solder area, allowing for a stronger solder
connection. The flip chip design allows for mounting on either side. Maximum trip time is
only 20 milliseconds at 8 amps, and it measures 3.0 x 2.3mm. Schurter Inc,
Granada Hills, CA. 
Current level indicator.The CR2530 features a factory-adjusted
"turn-on" point for the attached snap-in panel-mount LED. The non-contact,
self-powered indicator monitors current flow by routing a current carrying wire through
the indicator window opening. CR Magnetics, Inc,Fenton, MO. 
Spill-proof battery. The YIX50L-BS sealed lead-acid
replacement battery uses gas recombinant technology. Acid is absorbed inside the battery
to prevent leaks. The lead-calcium plate design holds its charge longer. Yuasa, Inc,
Reading, PA. 
Power inductor. This family of high current surface mount
power inductors delivers high efficiency in a minimum amount of board space. The Power Pod
delivers up to six watts of power per cubic inch. The line is well suited for use in
microprocessor and distributed power applications including power supplies, power
regulators, and DC to DC converters -- especially in equipment for test & measurement,
medical diagnostics and industrial process control. Gowanda Electronics, Gowanda,
NY.
Lithium batteries. This company offers rechargeable lithium
ion polymer batteries featuring a building-block design that can be custom configured into
various voltages and capacities for military, aerospace, underwater research and other
applications. The building-block design consists of thin profile cells, about the size of
a credit card, which incorporate a patented lithium ion solid polymer rechargeable
technology. Battery Engineering, Inc, Canton, MA. 
Mountable power converter. The LF300RW Series is designed to
provide miniature size, a high performance envelope and the ease of automated assembly at
a low cost. Features include miniature SMT packaging, 3W of output power, 1500 VDC
input/output isolation and tight line/load regulation., Twenty-one single and dual output
models provide output combinations of 3.3, 5, 12, 15, ±5, ±12 or ±15 VDC, with 2:1
input ranges of 9 to 18 VDC, 18 to 36 VDC or 36 to 75 VDC. MicroPower Direct,
Stoughton, MA.
