Resistor offers overload and pulse handling capabilities.
Press Release Summary:
Power Metal Strip® WSE805 resistor combines 0.25 W rating and resistance range of 10-10,000 ohms in 0.080 x 0.050 in. package with 0.025 in. max. height. Surface-mount component can replace low-power, leaded, wirewound resistors. It has low TCR of 15 ppm/°C, tight tolerance to 0.1%, low noise of less than -40 dB, and low inductance of less than 0.08 µH. Applications include voltage amplifier circuits, precision voltage divider circuits, and high-frequency circuits.
Original Press Release:
Vishay's New 0805-Size Surface-Mount Power Metal Strip® Resistor Matches 0.25-W Rating of 1206-Size Resistor, Enabling Significant Board-Space Reduction
MALVERN, PENNSYLVANIA - January 16, 2004 - Vishay Intertechnology, Inc. (NYSE: VSH) today announced the release of a new 0.25-W surface-mount Power Metal Strip® resistor with a power rating that matches that of larger 1206 size resistors while offering superior overload and pulse-handling capability.
The new WSE0805 resistor is the industry's first device to combine a 0.25-W rating and a resistance range of 10 Ù to 10,000 Ù in the very small 0805 package, which measures 0.080 in. by 0.050 in. [2.30 mm by 1.27 mm] with a maximum height of 0.025 in. [0.64 mm]. As a result, this surface-mount component may be used in lieu of larger components with equivalent power capability, thereby saving board space and enabling the design of smaller and lighter consumer products. With its high power rating, the WSE0805 is also suitable for replacing low-power leaded wirewound resistors.
Typical applications for the WSE0805 resistor include voltage amplifier circuits, precision voltage divider circuits, and high-frequency circuits in telecommunications, automotive, industrial instrumentation, consumer electronics, and computing systems.
The new resistor from Vishay Dale features a low TCR of 15 ppm/°C, a resistance range from 10 Ù to 10,000 Ù, and tight tolerance down to 0.1%, as well as low noise of <-40 dB, very low inductance of <0.08 µH, and a voltage coefficient of <0.00001%/V (<0.1 ppm/V). It is rated for an operating temperature range of -65 °C to +150 °C and provides resistance to thermal shock, moisture, and high-temperature bonding exposure.
Available in tape-and-reel packaging, samples and production quantities of the new WSE0805 0.025-W Power Metal Strip resistors are available now, with a lead time of six to eight weeks for larger orders. Pricing for U.S. delivery is $0.20 per piece.
