From passives to power devices, component manufacturers continue to develop smaller devices as mobile device designers look to shrink the size and thickness of their products, and/or pack higher functionality into their devices. But it's not only consumer electronics OEMs looking for miniature components, designers of communications, military, industrial and medical products also need to address the portability, weight and size of their designs. Component manufacturers are up to the task and are helping their customers meet their goals by continuing to develop new materials, new manufacturing processes, and new packaging. In many cases, component makers also are able to improve the performance of the components as they continue to shrink their size. Here's my selection of 10 hot products that truly fall into the category of tiny components.

TI Delivers Single-Chip Battery Gauge with Protection
TI claims the first single-chip battery gauge with integrated protection designed to protect single-cell Li-Ion batteries in space-constrained designs. This device is housed in a 1.9- x 2.7- x 0.6-mm, 15-bump, CSP package.
Molex Audio Receivers Save Space
Aimed at hearing-aid and other small audio applications, Molex's balanced armature audio receivers, measuring 80-mm3, deliver up to a 20 percent space savings versus similar competitive products, and up to 75 percent savings compared to dynamic receivers.
Murata Claims Tiniest Ferrite Beads
Driven by industry demand for ultra-small components, Murata offers the smallest chip ferrite bead, packaged in a 008004 size (0.25 x 0.125 mm).
Omnetics Mini Connectors Target Rugged Apps
Delivering size and weight reduction, Omnetics' Nano miniature connectors provide up to 2 Gbits/s speed in extremely rugged environments.
Raltron Shrinks Clock Oscillator
Raltron is on a roll, packaging its frequency control devices in ever smaller packages. One example is the company's clock oscillator, which is housed in a 2.0- x 1.6- x 0.65 mm package size.
Raltron Claims Smallest Microprocessor Crystal
Raltron claims the industry’s smallest microprocessor crystal with the introduction of its Model R1612, housed in a 1.6 x 1.2 x 0.4 mm ceramic package.
TI MOSFETs Tout Lowest On-Resistance
Not only does TI's ultra-small FemtoFET MOSFETs tout the lowest on-resistance of below 100 milliohms, saving power and extending battery life of mobile devices, it also comes housed in a small 0.6- x 1.0- x 0.35-mm package.
Mtron Shrinks TCXOs
Another small frequency control device was developed by MtronPTI. It now houses its high stability, ultra-miniature TCXOs in package sizes as small as 2.5 x 2.0 mm, which is an area reduction of 7X compared to standard 5- x 7-mm packages.
Coilcraft Unveils Mini Flyback Transformer
Coilcraft's LPR6235 series of coupled inductors measure 6- x 6-mm with a 3.5-mm height. Energy harvesting is a target applications.
C&K Debuts Ultra-Mini Slide Switch
Last but not least, targeting applications with very tight board space and height requirements is C&K's PCM series of ultra-miniature, low-profile slide switches, which can be used in a variety of applications.
