SR73 Current Sense Chip Resistor
 |
- 66% Smaller KOA Speer’s new thick film 0201-SR731H resistor has a power rating of 0.10 Watts, a T.C.R. of 0 ~ 500ppm/ºC and a low-Ohm resistance range of 0.18 – 10?. The new resistor size also has tolerances of +/-1 or +/-5%, with a maximum overload voltage of 2.5V and an absolute max. working voltage of 1.0V. The miniature size of the new 0201 device makes the chip ideal for applications such as computers, HDDs, cellular phones, power supplies and motor circuits. The SR73 current sense chip resistor is also available in the following sizes: 0402, 0603, 0802, 1206, 1210, 2010 and 2512.The new generation of compact fans are divided into five series with sizes ranging from 80 to 172 mm. Each series represents the benchmark in its class with respect to air performance and pressure build-up with optimum motor efficiency and long service life. These compact fans reach nominal speeds up to 14,000 rpm and operating values that had previously been attained only by large fans. To harness this much power in a minimal space requires outstanding strength. To equip the housing, stator, bearing system and rotor for high performance, a one-of-a-kind housing design was developed with mechanical precision down to the smallest of detail.

New Flat Chip Resistor
 |
- 55% Smaller KOA Speer Electronics, Inc. introduces a new smaller sized, precision surface mount resistor with 1% tolerance designed to meet the continuing demand for miniature components for portable devices. KOA Speer’s 01005-RK73H1F device, measuring 0.4 x 0.2 x 0.1 mm, is 55% smaller than an 0201 chip resistor. With more sensitivity to process and design variables, the new 01005(1F) size is suitable for a wide range of applications that require compact, reliable chip surface mount resistors. KOA Speer’s new thick film 01005-RK73H1F resistor has a power rating of 0.33 Watts, a resistance range of 10W ~ 1M, at ±1% tolerance and a T.C.R. of ±250 ~ ±300ppm/°C. The surface mount resistor is manufactured per KOA Speer’s high performance RK73H standards, and provides superior resistance over standard chip resistors in maximum working voltage. Additionally, the product is available with lead-free terminations to meet EU RoHS requirements. Used primarily on leading edge portable products where size and/or weight are key selling points, the 01005 size chip surface mount resistor is ideal for applications such as package-on-package (PoP) high density PCBA’s, mobile phones RF modules, micro drives, handheld memory products (SD cards), portable application-mobile phones and digital cameras.
